The fatty acid pattern in three hydrocarbon-utilizing bacteria during growth on various substrates was examined. The predominant fatty acids in acetate-grown cells were C(16), C(16:1), C(18:1), and Br-C(19) and the major fatty acids in propane-grown cells were C(15), C(17), C(17:1), C(18:1), and Br-C(18). When one organism (Mycobacterium sp. strain OFS) was grown on the n-alkanes from C(13) to C(17), the major fatty acid in the cells was of the same chain length as the substrate. Studies on the incorporation of acetate into the cellular fatty acids of microorganisms growing on C(15) and C(17)n-alkanes suggest that the oxidative products of the substrate are incorporated into the cellular fatty acids without degradation to acetate.
研究了三种利用碳氢化合物的细菌在不同底物上生长时的脂肪酸模式。在以乙酸盐为底物生长的细胞中,主要脂肪酸为C(16)、C(16:1)、C(18:1)和Br-C(19);在以丙烷为底物生长的细胞中,主要脂肪酸为C(15)、C(17)、C(17:1)、C(18:1)和Br-C(18)。当一种微生物(分枝杆菌属菌株OFS)在C(13)至C(17)的正构烷烃上生长时,细胞中的主要脂肪酸与底物具有相同的链长。关于乙酸盐掺入在C(15)和C(17)正构烷烃上生长的微生物细胞脂肪酸中的研究表明,底物的氧化产物在不降解为乙酸盐的情况下掺入细胞脂肪酸中。
