New extracellular fatty acids in culture filtrates of Sporothrix flocculosa and S . rugulosa

Two new and rare unsaturated, extracellular fatty acids were identified in the culture filtrates of the biocontrol fungi, Sporothrixflocculosa and S. rugulosa. 16-Methyl-9E-nonadecenoic acid (1) and (Z,Z)-10,14-eicosadienoic acid (2) were characterized on the basis of infrared (IR) and nuclear magne...

Description
Summary:Two new and rare unsaturated, extracellular fatty acids were identified in the culture filtrates of the biocontrol fungi, Sporothrixflocculosa and S. rugulosa. 16-Methyl-9E-nonadecenoic acid (1) and (Z,Z)-10,14-eicosadienoic acid (2) were characterized on the basis of infrared (IR) and nuclear magnetic resonance spectra ( 13 C and 1 N NMR), and gas chromatographic – mass spectrometric data (GC–MS). The structure of compounds 1 and 2 was confirmed by oxidative degradation to the known standards, dimethyl azelate, dimethyl succinate, dimethyl sebacate, and methyl caproate. Keywords: unsaturated fatty acids, fungi.
