What is the meaning of microbial activity?

What is the meaning of microbial activity?

Abstract. Soil microbial activity that reflects microbiological processes of soil microorganisms is the potential indicator of soil quality, as plants rely on soil microorganisms to mineralize organic nutrients for growth and development.

What is microbial action in food?

Microorganisms associated with foods can be categorized as spoilage, pathogenic, or useful. … Also bacterial enzymes may effect slow deterioration of frozen or dried foods during long-time storage. These changes diminish the quality characteristics of foods and may render them ultimately unfit for human consumption.
