A mutant of Bacillus subtilis synthesizes a variety of omega-alicyclic fatty acids when fed with the respective alicyclic carboxylic acids. These fatty acids are: omega-cyclopropane, omega-cyclobutane, omega-cyclopentane, omega-cyclohexane, and omega-cyclohexene fatty acids. These unusual fatty acids did not lead to an inhibition of growth at 37 degrees C and pH 7. The selective advantage of these fatty acids under extrene conditions was studied in comparison with the acidophilic, thermophilic bacterium B. acidocaldarius, which normally contains a high proportion of omega-cyclohexane fatty acids.
枯草芽孢杆菌的一个突变体在被投喂相应的脂环族羧酸时会合成多种ω-脂环族脂肪酸。这些脂肪酸包括:ω-环丙烷、ω-环丁烷、ω-环戊烷、ω-环己烷和ω-环己烯脂肪酸。这些不同寻常的脂肪酸在37摄氏度和pH值为7的条件下不会抑制生长。与通常含有高比例ω-环己烷脂肪酸的嗜酸嗜热菌嗜酸热硫化叶菌相比,研究了这些脂肪酸在极端条件下的选择优势。
