THE INFLUENCE OF SOME EXTERNAL FACTORS ON THE GROWTH OF HYPHAL BODY OF HYPSIZYGUS MARMOREUS / 微生物学通报

ABSTRACT

This paper is about the research on the growth of jyphal body of Hypsizygus marmoreus under the condition of different culture mediums, tempertures, pH, cardon and nitrogen sources. The result shows that Hypsizygus marmoreus can grow on various culture mediums. It grows best on the Culture medium of malt extract agar, but can not grow well on the PDA composite culture medium; the hyphal body can grow well at the temperture of 20—25℃, grows slowly at 10—30℃, but can not grow at 35℃; it can grow when pH is 5 to 8, but the best range of pH is 6.5—7.0; the nutriment assimilation is different with the different sources of carbon and nitrogen, the best carbon source is maltose, best nitrogen source is bacto-peptone.
