The application of plant beneficial microorganisms has been widely accepted as an efficient
alternative to chemical fertilizers and pesticides. Isolation and selection of efficient microorganisms,
their characterization and testing in soil-plant systems are well studied. However, the production
stage and formulation of the final products are not in the focus of the research, which affects the
achievement of stable and consistent results in the field. Recent analysis of the field of plant beneficial
microorganisms suggests a more integrated view on soil inoculants with a special emphasis on
the inoculant production process, including fermentation, formulation, processes, and additives.
This mini-review describes the different groups of fermentation processes and their characteristics,
bearing in mind different factors, both nutritional and operational, which affect the biomass/spores
yield and microbial metabolite activity. The characteristics of the final products of fermentation
process optimization strategies determine further steps of development of the microbial inoculants.
Submerged liquid and solid-state fermentation processes, fed-batch operations, immobilized cell
systems, and production of arbuscular mycorrhiza are presented and their advantages and disadvantages
are discussed. Recommendations for further development of the fermentation strategies for
biofertilizer production are also considered.
