Notes:
The production of L-glutamic acid from hydrocarbons by a newly isolated bacterium, which was identified as Corynebacterium, was investigated. The outstanding characteristic of this bacterium was found to be an accessory requirement of thiamine for growth. The optimum concentration of thiamine for growth was 50 μg./liter, while that for L-glutamic acid production was 3-5 μg./liter. n-Paraffins ranging from dodecane to heptadecane were best for L-glutamic acid production, and about 5 g. of L-glutamic acid were obtained from 30 g. of these individual n-paraffins. On the other hand, a tracer experiment using oxygen-18 revealed that molecular oxygen was incorporated into L-glutamic acid produced from dodecane. Based on the incorporation value of molecular oxygen in L-glutamic acid, a hypothetical pathway for the biosynthesis of L-glutamic acid from dodecane was discussed.
