| pubmed-article:814067 | pubmed:abstractText | Addition of different concentrations of sodium arsenite to the fermentation medium used for the production of mitomycin antibiotics by Streptomyces caespitosus hindered the biosynthesis of mitomycins and led to the accumulation of 2-oxoglutarate, pyruvate and acetone. Mitomycin C isolated and purified using thin-layer chromatography in low concentration of about 0.1 mug/ml did not affect the RNA, DNA and protein biosynthesis of the growing Bacillus subtilis, while at 10 mug/ml mitomycin C markedly affected RNA, DNA and protein biosynthesis. | lld:pubmed |
