Journal of Bioscience and Bioengineering  coverThe 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. 134 Cover Illustration

The white koji fungus, Aspergillus luchuensis mut. kawachii, is an industrially important microorganism used in the production of shochu, a traditional distilled alcoholic beverage indigenous to Japan. It secretes large amounts of citric acid that can prevent the growth of contaminating microbes during the fermentation process. The citrate exporter CexA plays a key role in the overproduction of citric acid. The photograph shows the vegetative hyphae of A. luchuensis mut. kawachii.
