One plant of 8157 microorganism of penicillium chrysogenum cubic centimetre

摘要

The penicillium chrysogenum CCM 8157 of the microorganism of the bacterial strain can produce ospen G in higher concentration than pervious strain. Concentration is higher, realizes mutant strain undertaking and is exposed to suitable mutagens, by passively selecting and selecting adjuster mutant. Penicillin fermentation production medium contains carbon source, nitrogen, sulphur, phosphorus, microelement, chalk, the side chain and defoaming agent of presoma. Optimum culturing temperature is 25 degrees Celsius. Under above-mentioned optimum condition, which is generated according under laboratory condition about 45,The every 1 milliliter of fermentation in 168 hours of the ospen of 000 unit.
