After reading this article you will learn about the requirements and procedure of litmus milk reactions. Milk sugar lactose, the milk proteins casein, lacto-albumin and lacto-globulin are the milk substrates that can be transformed by microorganisms, bringing about changes in pH. In order to distinguish the metabolic changes, a pH indicator, the oxidation reduction indicator […]

Actinomycetes: Isolation and Identification | Microbial Biotechnology
In this article we will discuss about the isolation and identification of actinomycetes. Isolation of Actinomycetes: This group of prokaryotes are ubiquitious and are found in all ecosystems. Some genera like Actinomyces are anaerobic and others like Frankia (symbiotic) require specialised growth media and incubation condition. To isolate them from soil, special treatments are essential. […]
