M9 and M17 have been studied , and the culture conditions of the two strains using potato starch wastewater as nutrient medium are optimized .

研究了两株根霉M9和M17复配产生的复合型微生物絮凝剂的絮凝特性，并优化了马铃薯淀粉废水对该复合菌的培养条件。

The lactic acid bacteria were isolated by semi-selective medium , MRS and M17 culture , and were identified by sugar fermentation experiments , RAPD fingerprint and PCR . Three kinds of lactic acid bacteria from DVS were isolated .

本研究首先利用M17和MRS半选择性培养基对DVS乳酸菌种进行分离，并采用糖发酵实验、RAPD指纹图谱实验和特异性PCR实验对菌种进行鉴定；
