TestingforBacteriaandFungi
AimIn cases of gross contamination the naked eye may identify the presence of bacteria and fungi. However, it is necessary to detect low-level infections by incubation of cell cultures and/or their products in microbiological broth. Equally these sterility tests can be used to confirm the absence of bacteria and fungi from the preparation which is important when preparing cell banks or cell culture products.Materials......阅读全文
