补充资料:细胞干重
分子式:
CAS号:

性质:细胞去除水分后的净重量,一般为湿重的10%~20%。在研究微生物的生长、发酵及其条件中,细胞干重是重要的测定参数。获得细胞干重的方法有二。(1)离心法:将待测培养液放入离心管中,反复作离心、清水洗涤三次后,进行干燥;干燥温度可采用105℃、100℃或红外线烘干,也可在80℃或40℃较低温度下进行真空干燥,然后称重。每个细菌细胞约重10-12~10-13g。(2)过滤法:尤其适用于丝状微生物如放线菌或真菌的干重测定,培养液用滤纸过滤后,留在纸上的菌丝体先用适量清水洗涤,再用上法烘干后称重,以最常见的大肠杆菌(Escherichia coli)为例,在液体培养物中,细胞的浓度一般为2×109个/ml,100ml培养液可得10~90mg干重细胞。
