Microbial fermentation offers advantages in biomass production, such as rapid growth rates, scalability, and the ability to utilize diverse carbon sources. Additionally, the fermentation process can be optimized to enhance the yield and quality of the biomass or specific products derived from it. Microbial biomass can be further processed to extract specific components or convert it into other forms, such as biofuels, bioplastics, or biochemicals.
Soil quality is directly affected by alterations in its microbiological, biological, biochemical, physical, and chemical aspects. The microbiological activities of soil can affect soil fertility and plant growth. The diversity and biomass of soil microbial communities are the major regulators of fundamental ecosystem processes, such as organic matter decomposition, nutrient (e.g., enzymes and hormones) cycling, and gaseous fluxes.

Edible microbial biomass derived from bacteria, yeasts, filamentous fungi or microalgae is a promising alternative to conventional sources of food and feed. Microorganisms are a good source of protein, vitamins and, in some cases, also contain beneficial lipids. The ability of microorganisms to use simple organic substrates for growth permits industrial-scale cultivation of edible microbial biomass.

Cellular biomass of microorganisms can be effectively used in the treatment of waste from various branches of the agro-food industry. Microbial biomass offers an economical option for removing heavy metals from wastes by the phenomenon of biosorption. Further biosorption potential of the biomass can be improved by various physical and chemical treatments.
Biosorbent | Examples/species |
Algae | Fucus, Chlamydomonas, Cladophora, Spirogyra sp. |
Bacteria | Bacillus sp., Vibrio sp., Geobactor sp., Pseudomonas sp., Desulfovibrio sp. |
Fungi | Pleurotus sp., Aspergillus sp., Penicillium sp., Rhizopus sp., Saccharomyces sp. |
