Factors affecting the microbial production of ferrichrome.
The isolation and general properties of ferrichrome have been reported elsewhere (l-3). Studies on the fundamental biological mechanism of action of this compound may be directed into one or both of two channels. The substance may be examined for its mode of action by using an organism for which it shows growth factor activity, i.e. Pilobolus kleinii. Alternatively, it may be studied in an orga...
متن کاملMicrobial Degradation of the Ferrichrome Compounds.
An unidentified Pseudomonas capable of growth on ferrichromes as sole sources of carbon and nitrogen was isolated by enrichment culture on ferrichrome A. The spectral shifts observed for the culture supernatant fluids and the degradation products which accumulated in the culture media during growth on these compounds indicated that initially the cyclic peptide rings are broken to yield simpler ...

the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
15 صفحه اولFactors affecting the production of candicidin.
Factors affecting candicidin synthesis and mycelial growth of Streptomyces griseus IMRU 3570 were studied. Inorganic phosphate was found to inhibit candicidin synthesis but to stimulate mycelial growth. Zinc, iron, and magnesium ions stimulated candicidin synthesis at relatively high concentrations in a complex medium but not in a synthetic medium. No other factors studied, such as temperature,...
