巴西曲霉定量菌株

巴西曲霉定量菌株介绍：

产品中文名称：巴西曲霉定量菌株
产品英文名称：Quantitative strains of aspergillus brasiliensis Varga et al.
参考用途：《GB 4789.28 培养基和试剂的质量要求》
形态特性：蔓延生长，产黑色孢子，边缘不规则，不透明，正面黑色，表面粗糙，质地干燥
培养基：马铃薯浸粉：10.0g，葡萄糖：20.0g，KH2PO4：3.0g，MgSO4·7H2O：1.5g，硫胺素：0.008g，琼脂：15.0g，pH：6.0±0.2（25℃）
培养条件：28℃；5天；好氧
培养方法：①按照培养条件先将菌培养成菌悬液； ②测量菌悬液吸光度，按照标准公式计算出菌悬液初始浓度； ③初始浓度乘以存活率即为冻干后实际浓度； ④根据冻干后实际浓度对菌悬液进行稀释获得目标浓度，然后进行分装、冻干；
存储形式：-80℃
提供形式：西林瓶
