Penicillium chrysogenum 79-6-S5 is another high-yielding strain, following the 77-5-327, selectad by The Sichuan Institute of .Antibiotics We carried outthe investigation on the characteristics of this strain and improved the technology of penicillin fermentation according to its characteristics. As a result of these experiments, this strain has been emploied in penicillin production and the yield of the penicillin with this strain is higher 7-11% than with previous strain, 77-5-327.

Penicillium chrysogenum79-6-55菌株是四川抗菌素工业研究所继77-5-327以后选育得到的又一株高产菌株。我们对该菌株的特性进行了考察,并且根据菌种的特性改进了青霉素的发酵工艺,使该菌株全面推上生产,青霉素的发酵单位较原来77-5-327菌株提高了7~11%。
