Activated carbon was found effective for purifying crude glycerol, which can be used for succinate production by recombinant E. coli

New Content ItemCrude glycerol is the main by-product from biodiesel production, and its efficient utilization for biochemical and biofuel production is of primal interest from economic and environmental protection points of view. However, the complex composition of crude glycerol has prevented such utilization due to its inhibition to the cell growth with slow glycerol consumption. Dr. Qing Li and his colleagues in East China University of Science and Technology (ECUST) found that activated carbon was quite effective for the purification of crude glycerol, which could be used as the carbon source for succinate production using recombinant Escherichia coli MLB (ΔldhA, ΔpflB) over-expressing phosphoenolpyruvate carboxykinase gene (pck) from MG1655. The efficient succinate production could be attained by two-stage fermentation starting with aerobic condition to promote the cell growth, followed by the anaerobic condition for succinate production with a high yield of 97% (mol/mol).

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
