Overproduction of clavulanic acid by extractive fermentation [PDF]

Electronic Journal of Biotechnology, 2015
Background: Clavulanic acid is an important beta-lactamase inhibitor produced as a secondary metabolite by the actinomycete Streptomyces clavuligerus. Clavulanic acid is chemically unstable; therefore, it is degraded during bacterial cultivation. In this

Extractive Ethanol Fermentation with Ethanol Recovery by Absorption in Open and Closed Systems

Fermentation
Conventional ethanol production has limitations, including substrate and product inhibitions, which increase both energy requirements for ethanol recovery and vinasse generation. Extractive fermentation, which removes ethanol as it is produced within the

Intensification of β-glucosidase enzyme production from Aspergillus niger using extractive fermentation with an aqueous two-phase system

Green Processing and Synthesis, 2017
An extractive fermentation approach in an aqueous two-phase system (ATPS) with wheat bran as a main substrate was used in this study to intensify the production of β-glucosidase enzyme (EC 3.2.1.21) from Aspergillus niger NRRL 322.

Evaluation of Ionic Liquids as In Situ Extraction Agents during the Alcoholic Fermentation of Carob Pod Extracts [PDF]

Fermentation, 2019
Anhydrous ethanol is a promising alternative to gasoline in fuel engines. However, since ethanol forms an azeotrope with water, high-energy-consumption separation techniques such as azeotropic distillation, extractive distillation, and molecular sieves ...
