Journal of Bioscience and Bioengineering  cover

The Journal of Bioscience and Bioengineering (JBB) is an international journal devoted to the rapid publication of papers describing original research in the field of biotechnology. JBB encourages and publishes new concepts in technology/methodology that significantly advance the understanding of bioscience and bioengineering and contribute to the development of chemical, pharmaceutical, medical, food, and agricultural industries. The Editorial Committee makes its best efforts to provide expeditious, rigorous and fair peer-review, ensuring the high quality of articles published in JBB.

JBB is published monthly (2 vols. in 12 issues) by the Society for Biotechnology, Japan and distributed outside Japan by Elsevier. Online version is available in ScienceDirect. The journal was first published in 1923, originally being named Jyozogaku Zasshi (in Japanese) and then renamed Hakkokogaku Zasshi (in Japanese) (1944), Journal of Fermentation Technology (1973), and Journal of Fermentation and Bioengineering (1989). It was given the current name in 1999. JBB has established itself as one of the most influential biotechnology journals and is now highly appreciated by scientists throughout the world.

JBB is abstracted/indexed in BIOSIS, Chemical Abstracts, Current Contents, EMBASE/Excerpta Medica, Elsevier BIOBASE/Current Awareness in Biological Sciences, ISI Biotechnology Citation Index, and MEDLINE/PubMed.

Vol. 126 Cover Illustration

Streptomyces species are gram-positive filamentous soil bacteria that produce a wide variety of secondary metabolites including antibiotics. Genome sequencing projects of many Streptomyces species have revealed that they have a greater genetic potential to produce over 20 secondary metabolites. However, most of secondary metabolite biosynthetic gene clusters are poorly or not expressed under laboratory growth conditions. Kenji Arakawa’s research group focuses on unique biosynthetic machinery of secondary metabolites, their structural redesign, and genome mining for activating silent secondary metabolite biosynthetic genes. The photograph shows various mutants of Streptomyces rochei grown on yeast extract/malt extract/glucose agar medium for 7 days.
