大肠杆菌K-12的温度敏感突变体在42 ℃时不饱和脂肪酸的生物合成受损，在高渗透压的培养基中继续生长并保持活力。在这些生长条件下，亲本菌株的50%的脂肪酸和突变菌株的80%的脂肪酸饱和。
A temperature-sensitive mutant ofEscherichia coliK-12, which is impaired in the biosynthesis of the unsaturated fatty acids at 42 C, continues to grow and remains viable in a medium with a high osmotic pressure. Under these growth conditions, 50% of the fatty acids of the parental strain and 80% of the fatty acids of the mutant strain are saturated.
