RESUMO
Gas chromatographic analysis of extracts from Bacillus caldolyticus and Bacillus caldotenax grown at 60, 70, or 80 C showed that both contain branched-chain fatty acids as major constituents at all temperatures tested. With increasing temperature, a decrease of i-C15 and an increase of i-C17 fatty acids were observed in both strains, as well as a decrease of i-C16 fatty acids corresponding to an increase of n-C16 fatty acids. The most obvious difference was that the shifts observed with B. caldolyticus occurred mainly upon raising the temperature to 10 C above, and in B. caldotenax upon lowering the temperature to 20 C below, the optimal growth temperature.
