Pseudomonas fluorescens, Proteus vulgaris, and Serratia marcescens, members of the microflora of soil and waste water, attacked methionine in the presence of glucose. The sulfur of methionine was released as methane thiol, dimethyl sulfide and dim ethyl disulfide. The volatile sulfur com pounds were qualitatively and quantitatively investigated by gas chromatography. Dimethyl disulfide was formed of methane thiol by various bacteria to a different extent. Growing in the presence of oxygen, S. marcescens oxidized most of the m ethane thiol to dim ethyl disulfide. In the presence of glucose. P. fluorescens dissimilated m ethionine with production of m ethane thiol and dimethyl disulfide. The dissimilation was stimulated with decreasing glucose concentration
A Journal of Biosciences: Zeitschrift für Naturforschung C (ZNC) is an international scientific journal for the emerging field of natural and natural-like products. ZNC publishes original research on the isolation, bio-chemical synthesis and bioactivities of natural products, their biochemistry, pharmacology, biotechnology, and biological activity and innovative developed computational methods for predicting their structure and/or function.
