Abstract

During the examinations we isolated bacteria from soil of some areas which are covered by litter and have previously been under crop. Our aim was to point out the possible differences in the lipid composition in case of bacterium strains of certain bacterium species which are living in the four different and diversely polluted ecological habitats. The environment can change and affect the bacterial lipid composition. The diversity of microorganism in soil is a critical factor, regarding the maintenance of good soil health. Changes in fatty acid composition of bacteria can indicate the environmental load on soils. According to our results, we can establish that different soil pollutions induce qualitative and quantitative changes in the lipid composition of microorganisms. FAME (fatty acid methyl-ester)-analysis can be effectively used for demodulation of environmental stress factors. According to our results, we can establish that different soil pollutions induce qualitative and quantitative changes in FAME composition of Bacillus brevis strains, among others:2-OH 10:0, C12:0, 2-OH 12:0, 3-OH 12:0, C14:1, C14:0 i-15:0, a-15:0 C15:1.
