Biosynthesis of Cephalosporin C: I. Factors Affecting the Fermentation.
A series of complex and synthetic media have been developed that are suitable for the production of cephalosporin C and cephalosporin N by a mutant strain of Cephalosporium (C.M.I. 49,137). dl-Methionine increased the yield of both antibiotics, with more effect on cephalosporin N. l-Cystine had a greater enhancing effect on formation of cephalosporin C than on formation of cephalosporin N in sy...
متن کاملFactors affecting fermentation reactions in the large bowel.
Quantitatively, the main sources of C and energy for bacteria growing in the human large intestine are starches and plant cell wall polysaccharides that escape digestion in the small bowel (Macfarlane & Cummings, 1991). These substances are depolymerized by hydrolytic enzymes produced by colonic bacteria, and their component sugars are fermented to a range of products, including organic acids, ...
متن کاملRecognizing Significant Human-Related Factors Affecting System Reliability
System reliability can be affected by many factors, some of which are not machine-related. An important category of these non-traditional factors are human-related (HR) factors, such as expertise, collaboration, and motivation. Operational systems consist of machinery as well as human operators and decision makers. Therefore, a risk analysis is incomplete if the probability of human error is no...
متن کاملFactors affecting alfa Amylase Production on Submerged Fermentation by Bacillus sp
The production of extracellular amylase by Bacillus spp was optimized in a submerged fermentation. The production of the enzyme was maximum at 10 h after inoculation. The effect of incubation period, pH of the medium and incubation temperature was optimized. The maximum productions of enzyme were obtained at 35°C and pH 7. Key-Words: alfa-Amylase production, Submerged fermentation Introduction ...
متن کاملPretreatments and Factors Affecting Saccharification and Fermentation for Lignocellulosic Ethanol Production
Lignocellulosic biomass can be utilized to produce ethanol, a promising alternative energy source for sustainable energy production and has the potential to be a valuable substitute. Various pretreatment techniques change the physical and chemical structures of the lignocellulosic biomass and improve the hydrolysis rate. The cost of ethanol production from lignocellulosic material is relatively...
