Longevity of a beneficial microbe or microbes in the soil or potting mix environment is a benefit for long-term crops. Bacteria tend to release their protective secondary metabolites for up to 4 weeks after application, even though they.may persist in the soil environment longer.ecause bacterial and fungal microorganisms (a.k.a. microbes) in soils and potting media are constantly vying for food, water, and space, soils are regarded as dynamic living environments.
Most commonly used microorganisms are yeast, bacteria, moulds, or a combination of these. A good example of microorganism usage in food production is the process of fermentation, which results in the production of organic acids, alcohols and esters. These help to either: 1  Preserve the food.athogenic microorganisms cause food-borne infections or intoxication, and include bacteria, viruses, parasites and moulds. It is important to note that pathogenic bacteria and viruses usually do not cause food spoilage, their contamination cannot be seen nor tasted.
