In microbiology, streaking is a technique used to isolate a pure strain from a single species of microorganism, often bacteria. Samples can then be taken from the resulting colonies and a microbiological culture can be grown on a new plate so that the organism can be identified, studied, or tested.
Besides the aforementioned groups of techniques, biotechnology also includes plant tissue culture methods, animal cell culture methods, and microbial fermentation methods. Subcategories This category has the following 17 subcategories, out of 17 total.
The IMViC tests are a group of individual tests used in microbiology lab testing to identify an organism in the coliform group.
