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 کاملAssessing factors affecting results of APS implementations
Purpose The purpose is to find out which factors, during APS implementations, that affects the effects of the implementation. Methodology A multiple case study is conducted where Critical Success Factors (CSFs) from ERP literature and effects from APS implementations are studied. Findings Findings show that several ERP CSFs most likely are applicable in APS implementations. Practical implicatio...
متن کاملExperimental factors affecting the robustness of DNA methylation analysis
Diverging methylation frequencies are often reported for the same locus in the same disease, underscoring the need for limiting technical variability in DNA methylation analyses. We have investigated seven likely sources of variability at different steps of bisulfite PCR-based DNA methylation analyses using a fully automated quantitative methylation-specific PCR setup of six gene promoters acro...
