The Journal of Bioscience and Bioengineering (JBB) aims to contribute to the advancement and dissemination of knowledge and technology in the fields of bioscience and biotechnology. JBB publishes papers on a broad range of topics in the areas of enzymology, physiology and biotechnology of microbes, plants, and animals; genetics, molecular biology, and gene engineering; brewing and food technology; environmental biotechnology; biochemical engineering; cell and tissue engineering; protein engineering; biomedical engineering; and bioinformatics. Genomics, systems biology, and structural biology, which hold much promise for the future, are also within the scope of JBB. The journal only considers submissions that report on the most significant and fundamental advances in the field of bioscience and bioengineering. Manuscripts that describe optimizations related to phenomena of narrow interest using conventional statistical approaches and/or describe exclusively computer simulation with conventional enzyme reaction models or molecular dynamics will be rejected without peer review. The brewing and food technology section welcomes researches that provide fundamental advances on fermentation, fermented foods and their process developments. Basic studies solely treating the chemical and/or medicinal aspects of food derivatives prepared by conventional pretreatment techniques are not appropriate for JBB. The cell and tissue engineering section covers research on cell culture engineering as it relates to regenerative medicine. Topics include the technologies for stem cell culture such as mass production, differentiation control, and tissue reconstruction. Studies in the field of pure cell biology and embryology are not appropriate for JBB. The biomedical engineering section covers topics related to bioprocess engineering in the field of medicine, including biomaterials, scaffolds, artificial organs, drug delivery systems, microfluidics, and micro-fabrication, but not deals with the topics mainly focusing on mechanical engineering. Studies in the field of basic medicine, pharmaceutical sciences, dentistry, and surgical technique are not suitable for JBB. The journal does not consider pathological, clinical, and epidemiological researches. Posting of preprints on preprint servers will not threaten the consideration of your manuscript for publication. However, the authors should carefully check and follow the Elsevier's guideline on preprint and show the DOI number in your cover letter if applicable. The journal accepts only those papers that are most significant to the field of bioscience and bioengineering. Thus, manuscripts focusing only on optimization of some objective function based on a conventional statistical approach will be rejected without peer review.
