The fatty acid content of C. michiganensis subsp. michiganensis cellular lipids in different culture conditions was investigated. It was established, that it lies in a narrow range C14-C18 and belongs to isoanteiso type. The species character is constant, independent of temperature, duration of cultivation and medium content dominance of saturated branched-chain fatty acids, among which the anteiso-acids dominate, generally a-C15. A response to the temperature modification of bacteria cultivation, medium and age of culture is expressed by relations between separate fatty acids. Thus the modifications of fatty acid content, connected with age of culture and temperature of cultivation, depend on a strain. The cultivation of bacteria on a rich medium in comparison with poor one enlarges the content of nonbranched-chain and anteiso-acids in lipids. |
