Optimum of Submerged Fermentation Parameters for Chromium-rich Mycelia of Coprinus comatus* / 微生物学通报

ABSTRACT

Submerged fermentation parameters for the chromium-rich mycel ia of Coprinus comatus was studied in optimal medium. According to the yield of organic Cr, the optimal fermentation parameters were obtained as follows the amount of CrCl_3 6H_2O in medium was 200mg/L; the inoculation volume was 8%~10%; the aeration ratio was 80250 (medium volume flask volume); the cul tural period was 5 days at 26℃ and at 100r/min. The highest yield of organic C r in mycelia of Coprinus comatus was 1597.88?g/100mL and the enrichment ra te of Cr was about 9.09%.
