Gamma linolenic acid (GLA) is a member of polyunsaturated fatty acids (PUFAs), it can be transformed to PGs and LTs in human bodies, which exert important regulation function in the cardiac and brain blood vessel system, breath system, liver, diabetic neuropathy and genital system.
Fermentation conditions were studied in this thesis, pH5.5 was the optimized pH value, inoculum higher than 10~6spore/mL could enhance the GLA yield, and too low level of dissolved oxygen was an important reason of low ...
