Temperature Affects Fatty Acids In Methylococcus Capsulatus

Abstract

According to report, temperature of growth of thermotolerant, methane-oxidizing bacterium Methylococcus capsulatus (Bath) affects both proportion of monounsaturated fatty acids and cis/trans ratio of these acids in cell membrane. Because suboptimum growth temperature is potential stress factor, it may be possible to use such cis/trans ratios as indices of stresses upon methane-oxidizing microbial communities. Research in microbiology of methanotrophs increasing because of possible commercial exploitation of these organisms as biocatalysts or as sources of useful polymers; knowledge of effect of temperature on ability of methanotrophs to utilize methane useful in optimization of conditions of growth.
