GENUS BACILLUS ENTHOMOPATHOGENIC STRAINS FATTY ACID LIPID COMPOSITIO

Abstract

Aim. To conduct a comparative analysis of cellular fatty acids composition of isolated bacterial strains belongs to the genus Bacillus, that have pathogenic for insects properties, and some typical representatives of this family. Methods. Fatty acid composition of cellular lipids established by chromatography, gas chromatography-mass spectrometry; calculating the mean, standard deviation and the confidence interval was performed using Microsoft Excel. Results. In the fatty acid composition of all studied strains revealed typical of the genus Bacillus set of fatty acids with carbon chain length from C10 to C18 atoms and particularly high content (more than 60–70% of the total peak area) of the branched (iso- and anteiso- forms) fatty acids has been found for the first time. Conclusions. Fatty acid profiles isolated strains Bacillus sp. significantly similar with collection and typical strains belonging to the species Bacillus thuringiensis.
