Screening for optimal protease producing Bacillus licheniformis strains with polymer-based controlled-release fed-batch microtiter plates

open access: yesMicrobial Cell Factories, 2021
Background Substrate-limited fed-batch conditions have the favorable effect of preventing overflow metabolism, catabolite repression, oxygen limitation or inhibition caused by elevated substrate or osmotic concentrations.

Effects of batch and fed-batch cultures on biomass and exopolysaccharide production of Lachnum calyculiforme

open access: yes浙江大学学报. 农业与生命科学版, 2010
The effects of cultural conditions on the biomass and exopolysaccharide (EPS) production of Lachnum calyculiforme were studied by shake flask experiments. Batch and fed-batch cultures were held in 5 L stirred fermentor, and the effects of the two culture

The physiology of erythromycin biosynthesis in cyclic fed batch culture [PDF]

open access: yesMicrobiology, 1995
Antibiotic production in Saccharopolyspora erythraea was significantly enhanced in cyclic fed batch culture (c.f.b.c) compared to batch culture, whereas chemostat culture resulted in reduced production. C.f.b.c. allowed the specific growth rate to be varied, with time, according to an asymptotically decreasing trajectory without the necessity for ...
