Abstract: | "The cytotoxicity of 13 microbial volatile organic compounds (MVOC) was studied using a human lung carcinoma epithelial cell line A549 in a colony formation assay and two colorimetric assays: the microculture tetrazolium assay (MTT assay) and the cellular protein assay (methylene blue-MB assay). For comparison, two known cytotoxic substances: the non-volatile mycotoxin gliotoxin and the mono-functional alkylating agent methyl methanesulfonate (MMS) were studied. Concentration-response curves for each agent were established and the IC50 value (concentration resulting in 50% inhibition of colony growth or absorbance) was estimated. There are differences in toxicity levels between the MVOC tested and gliotoxin and MMS. The most toxic MVOC was 1-decanol which was as effective as MMS in all test systems. 1-decanol was about 10-fold more toxic than the other MVOC. All MVOC tested were more than 1000-fold less toxic than gliotoxin" |
