The Manufacture of Penicillin
The preferred mold is Penicillium chrysogenum and the first stage of the process is the transfer of the mold to the fermenter from the test tube where it has been stored The whole process is aerobic it requires air The fermentation is carried out over 4 or 5 days at 25-27 176 C This gives a yield of about 05 penicillin...
