Measuring the Growth of Bacteria | Microbial Biotechnology
Article shared by :
In this article we will discuss about the principle, requirements and procedure for measuring the growth of bacteria by spectrophotometric method. Principle: This method relates cell number to turbidity of a broth culture. Turbidity or optical density (OD) is directly proportional to cell concentration. Requirements: 1. 10-12 hour E. coli broth culture maintained at lag […]

In this article we will discuss about the requirements and procedure for isolation of frankia. Frankia is an actinomycete which forms symbiotic association with non-leguminous plants and fix atmospheric nitrogen. There are over 24 genera from eight angiosperm families which have been reported to possess actinorhizal nodules on the root system. Abortive attempts to isolate […]
