Article types

Contributions falling into the following categories will be considered for publication: Original research papers, reviews and short communications. Please ensure that you select the appropriate article type from the list of options when making your submission. Authors contributing to special issues should ensure that they select the special issue article type from this list.

In the following paragraphs you will find a brief description of each contribution.

Research
These articles present original research and address a clearly stated specific hypothesis or question. Papers should provide novel approaches and new insights into the problem addressed. Manuscripts should be 3000 to 5000 words in length and they should have at least 15 references.
These articles should include:

  • Introduction: It should be brief and limited to the definition of the problem, the aims and purposes of the research and its relation with other studies in the field. Also the working hypothesis must be clearly stated.

  • Materials and methods: It should include relevant details on the experimental design and techniques so that the experiments can be repeated.

  • Results: Results should be clearly presented. Tables and figures should only be included if required to fully understand the data.

  • Discussion: The aim of this section is the interpretation of the results and their relation to the existing knowledge. The contribution to Biotechnology must be clearly stated. The information given in any part of the text may be cited but not repeated in the Discussion Section. Alternatively Results and Discussion can be presented in one section.

  • Acknowledgments: The acknowledgments of the contributions of colleagues can be stated in this section.

  • Financial support: The acknowledgments for financial support should be cited here.

For stylistics details, please refer to PREPARATION below.

Review
Review articles must be authored by experts in the field area. They are an attempt by one or more authors to sum up the current state of the knowledge on a particular topic. Ideally, the author searches for everything relevant to the topic, and then sorts it all out into a coherent view of the "state of the art" as it now stands and promotes a personal view on the subject. Review articles should have at least 80 references and they should have between 4000 and 6000 words in length.

Review articles should inform about: the main researchers working in the field; recent major advances and discoveries; significant gaps in the research; current debates; future directions. They include an abstract, an introduction that outlines the main theme, brief subheadings, and an outline of important unresolved questions.

For stylistics details, please refer to PREPARATION below.

Short communications
A short communication is a concise, but independent report representing a significant contribution to biotechnology.
Short communication is not intended to publish preliminary results. Only if these results are of exceptional interest and are particularly topical and relevant will be considered for publication. It should be 3000 words in length, and could include two figures or tables. It should have at least 8 references.

The text should be divided into the following sections: introduction, experimental (or theoretical), results, and discussion. Results and discussion sections may be combined.

Submission

Our online submission system guides you stepwise through the process of entering your article details and uploading your files. The system converts your article files to a single PDF file used in the peer-review process. Editable files (e.g., Word, LaTeX) are required to typeset your article for final publication. All correspondence, including notification of the Editor's decision and requests for revision, is sent by e-mail.

Submit your article
Please submit your article via http://ees.elsevier.com/ejbt.

Referees

Please suggest at least four internationally recognized researchers as referees with their full name, affiliation and email address. We recommend that at least one of them should be a member of the editorial board of the Electronic Journal of Biotechnology (for a list of board members see http://www.elsevier.com/locate/ejbt).

GenBank/DNA sequence linking

DNA sequences and GenBank Accession numbers: Many Elsevier journals cite "gene accession numbers" in their running text and footnotes. Gene accession numbers refer to genes or DNA sequences about which further information can be found in the database at the National Center for Biotechnical Information (NCBI) at the National Library of Medicine. Elsevier authors wishing to enable other scientists to use the accession numbers cited in their papers via links to these sources, should type this information in the following manner:

For each and every accession number cited in an article, authors should type the accession number in bold text. Letters in the accession number should always be capitalized. (See Example 1 below). This combination of letters and format will enable Elsevier's typesetters to recognize the relevant texts as accession numbers and add the required link to GenBank's sequences.

Example 1: "GenBank accession nos. AI631510, AI631511, AI632198, and BF223228, a B-cell tumor from a chronic lymphatic leukemia (GenBank accession no. BE675048), and a T-cell lymphoma (GenBank accession no. AA361117)".

Authors are encouraged to check accession numbers used very carefully. An error in a letter or number can result in a dead link. In the final version of the printed article, the accession number text will not appear bold or underlined (see Example 2 below).

Example 2: "GenBank accession nos. AI631510, AI631511, AI632198, and BF223228, a B-cell tumor from a chronic lymphatic leukemia (GenBank accession no. BE675048), and a T-cell lymphoma (GenBank accession no. AA361117)".

In the final version of the electronic copy, the accession number text will be linked to the appropriate source in the NCBI databases enabling readers to go directly to that source from the article.

Peer review

This journal operates a single blind review process. All contributions will be initially assessed by the editor for suitability for the journal. Papers deemed suitable are then typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor is responsible for the final decision regarding acceptance or rejection of articles. The Editor's decision is final. More information on types of peer review.

Use of word processing software
It is important that the file be saved in the native format of the word processor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier). Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. See also the section on Electronic artwork below.
To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your word processor.

LaTeX
You are recommended to use the Elsevier article class elsarticle.cls to prepare your manuscript and BibTeX to generate your bibliography.
Our LaTeX site has detailed submission instructions, templates and other information.

Subdivision - numbered sections
Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the text'. Any subsection may be given a brief heading. Each heading should appear on its own separate line.

For details on structure revise the section Article types above.

Essential title page information

Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
Author names and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and the e-mail address of each author.
Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, and also post-publication. If possible, indicate an alternative e-mail for contact. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding author.The Corresponding author is responsible that every coauthor has contributed to the ms and has accepted to publish the manuscript.
Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a "Present address" (or "Permanent address") may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.

Abstract

The abstract of the manuscript should not exceed 250 words and must be structured into separate sections:

  • Background, the context and purpose of the study;
  • Results, the main findings;
  • Conclusions, brief summary and potential implications.

Please minimize the use of abbreviations and do not cite references in the abstract.

In the case of review articles, the abstract should be submitted as one section.

Keywords

Authors must provide between four and eleven keywords, which must not be part of the title of the paper. Also Keywords will be added in order to improve manuscript visibility.

Abbreviations
Define abbreviations that are not standard the first time they are mentioned. Abbreviations that are unavoidable in the abstract must be defined at their first mention there. Ensure consistency of abbreviations throughout the article.

Acknowledgements and financial support

Indicate Acknowledgments and Financial support in separate sections at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List in acknowledgments those individuals who provided help during the research (e.g., providing language or writing assistance, or proof reading the article, etc.).

Formating of funding sources
List funding sources in this standard way to facilitate compliance to funder's requirements:

Funding: This work was supported by the National Institutes of Health [grant numbers xxxx, yyyy]; the Bill & Melinda Gates Foundation, Seattle, WA [grant number zzzz]; and the United States Institutes of Peace [grant number aaaa].

It is not necessary to include detailed descriptions on the program or type of grants and awards. When funding is from a block grant or other resources available to a university, college, or other research institution, submit the name of the institute or organization that provided the funding.

If no funding has been provided for the research, please include the following sentence:

This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

Nomenclature and units

Follow internationally accepted rules and conventions: use the international system of units (SI) (http://physics.nist.gov/Pubs/SP330/sp330.pdf). If other quantities are mentioned, give their equivalent in SI.

Math formulae
Please submit math equations as editable text and not as images. Present simple formulae in line with normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).

References

For original articles (research, short communications), at least 75% of the references must be from the Web of Science Core Collection and at the same time from the last decade. Also the DOI number must be included at the end of each reference.

Citation in text
Please ensure that every reference cited in the text is also present in the reference list (and vice versa). References in abstract should be avoided. Unpublished results; personal communications and thesis are not allowed. Citation of a reference as "in press" implies that the item has been accepted for publication.

Web references
As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.

Reference management software
Most Elsevier journals have their reference template available in many of the most popular reference management software products. These include all products that support Citation Style Language styles, such as Mendeley and Zotero, as well as EndNote. Using the word processor plug-ins from these products, authors only need to select the appropriate journal template when preparing their article, after which citations and bibliographies will be automatically formatted in the journal's style. If no template is yet available for this journal, please follow the format of the sample references and citations as shown in this Guide.

Users of Mendeley Desktop can easily install the reference style for this journal by clicking the following link:
http://open.mendeley.com/use-citation-style/electronic-journal-of-biotechnology
When preparing your manuscript, you will then be able to select this style using the Mendeley plug-ins for Microsoft Word or LibreOffice.

Reference style
Text: Indicate references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s) must always be given.

Example: '… as demonstrated [3,6]. Barnaby and Jones [8] obtained a different result …'

Reference section: Number the references (numbers in square brackets) in the list in the order in which they appear in the text.

Examples:

Reference to a journal publication:

Artwork

Electronic artwork
General points
• Make sure you use uniform lettering and sizing of your original artwork.
• Embed the used fonts if the application provides that option.
• Aim to use the following fonts in your illustrations: Arial, Courier, Times New Roman, Symbol, or use fonts that look similar.
• Number the illustrations according to their sequence in the text.
• Use a logical naming convention for your artwork files.
• Provide captions to illustrations separately.
• Size the illustrations close to the desired dimensions of the published version.
Formats
If your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel) then please supply 'as is' in the native document format.
Regardless of the application used other than Microsoft Office, when your electronic artwork is finalized, please 'Save as' or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):
EPS (or PDF): Vector drawings, embed all used fonts.
TIFF (or JPEG): Color or grayscale photographs (halftones), keep to a minimum of 300 dpi.
TIFF (or JPEG): Bitmapped (pure black & white pixels) line drawings, keep to a minimum of 1000 dpi.
TIFF (or JPEG): Combinations bitmapped line/half-tone (color or grayscale), keep to a minimum of 500 dpi.
Please do not:
• Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); these typically have a low number of pixels and limited set of colors;
• Supply files that are too low in resolution;
• Submit graphics that are disproportionately large for the content.

Color artwork
Please make sure that artwork files are in an acceptable format (TIFF, EPS or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable color , then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., Science Direct and other sites) regardless of whether or not these illustrations are reproduced in color in the printed version.

Figure captions
Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

The figures (photographs, drawings) must be numbered with Arabic numerals. Footnotes can be included below the figure.

Figures that include more than one image should be labeled as a, b, c, etc. (lower case, use black or white bold according to the figure).

Example:

Graphs
Graphs should be cited as figures and must be numbered with Arabic numerals. Footnotes can be included below the figure.

Graphs that include more than one image should be labeled as a, b, c, etc. (Arial lower case). They must be in 2D and have a title. In case they have legend, it must be placed below the image. They should be built with Arial font and in the color palette called "Trek" (warm earth colours). See page layout in MS Office 2007. For the Spanish version the colour palette is called "Viajes". Graphs must be send in editable formats (MS excel if possible. We also accept Sigma plot and Origin) in order to make formal changes (colur, fonts, size, etc.).
