Featured article: Transcriptomic analysis of Aspergillus niger strains reveals the mechanism underlying high citric acid productivity

New Content Item Aspergillus niger has been paid much attention for its ability to produce fair amount of citric acid (CA). However, its metabolic regulation mechanisms are not much known. Dr. Xie and his co-workers investigated the transcriptional regulation mechanisms for three different types of A. niger strains, and found that many key genes in the carbohydrate hydrolysis and polypeptide degradation pathway were upregulated in the strain YX-1217 (possesing high CA production ability) as compared to other strains. Moreover, they also found that a relatively strong electron transport chain, a regeneration system for NAD+/NADP+ etc. have contributed to the high CA production rate. These findings are quite useful for further metabolic engineering towards higher CA production in practice.

Aims and scope

Bioresources and Bioprocessing (BIOB) is a peer-reviewed open access journal published under the brand SpringerOpen. BIOB aims at providing an international academic platform for exchanging views on and promoting research to support bioresource development, processing and utilization in a sustainable manner. As an application-oriented research journal, BIOB covers not only the application and management of bioresource technology but also the design and development of bioprocesses that will lead to new and sustainable production processes.

BIOB publishes original and review articles on most topics relating to bioresource and bioprocess engineering, including:

  • Biochemical and microbiological engineering
  • Biocatalysis and biotransformation
  • Biosynthesis and metabolic engineering
  • Bioprocess and biosystems engineering
  • Bioenergy and biorefinery
  • Cell culture and biomedical engineering
  • Food, agricultural and marine biotechnology
  • Bioseparation and biopurification engineering
  • Bioremediation and environmental biotechnology
