A white microbial culture refers to a population of microorganisms that appear white in color when grown on a culture medium. This culture may consist of a single species or a combination of different species of bacteria, fungi, or other microorganisms.
The white color of the microbial culture can be attributed to a variety of factors, such as the production of pigments, the presence of spores or mycelium, or the accumulation of extracellular substances. Some examples of white microbial cultures include lactobacillus, streptococcus thermophilus, and candida albicans.
