Production of volatile organic sulfur compounds (VOSCs) by basidiomycetous yeasts.
Thirty-seven basidiomycetous yeasts belonging to 30 species of seven genera were grown on media containing l-cysteine or l-methionine as sole nitrogen sources with the objective of evaluating volatile organic sulfur compound (VOSC) production. The headspace of yeast cultures was analyzed by the solid-phase microextraction (SPME) sampling method, and volatile compounds were quantified and identi...
متن کاملInfluence of menstrual cycle and salivary ß-estradiol on volatile sulfur compound
BACKGROUND: ß -estradiol is a steroid sex hormone that plays important role in oral physiology. The aim of this study was to determin the association of the menstrual cycle and salivary ß-estradiol with the production of volatile sulfur compounds (VSC).METHODS: In this cross-sectional study, twenty female dental students in good oral and general health were recruited for evaluation of VSC, sali...
متن کاملRoles of methanogens on volatile organic sulfur compound production in anaerobically digested wastewater biosolids.
Land application of wastewater biosolids is both economical and beneficial to resource recycling. However, this environmentally friendly practice can be at risk due to odor complaints. Volatile organic sulfur compounds (VOSCs) including methanethiol, dimethyl sulfide, and dimethyl disulfide, have been identified as major contributors to biosolids odor. In this study, methanogens were shown to p...
متن کاملVolatile-sulfur-compound profile distinguishes Burkholderia pseudomallei from Burkholderia thailandensis.
Solid-phase microextraction gas chromatography-mass spectrometry (SPME-GCMS) was used to show that dimethyl sulfide produced by Burkholderia pseudomallei is responsible for its unusual truffle-like smell and distinguishes the species from Burkholderia thailandensis. SPME-GCMS can be safely used to detect dimethyl sulfide produced by agar-grown B. pseudomallei.
متن کاملInhibitory Effect of Enterococcus faecium WB2000 on Volatile Sulfur Compound Production by Porphyromonas gingivalis
Volatile sulfur compounds (VSCs) produced by oral anaerobes are the major compounds responsible for oral malodor. Enterococcus faecium WB2000 is recognized as an antiplaque probiotic bacterium. In this study, the effect of E. faecium WB2000 on VSC production by Porphyromonas gingivalis was evaluated, and the mechanism of inhibition of oral malodor was investigated. P. gingivalis ATCC 33277 was ...
