Selection of the best performing strain, maintenance and stabilization of the isolate and development of a reliable bioassay procedure are necessary prerequisites to the development of small-scale production systems and scaling-up of the selected fermentation process to industrial level. Solid-state, submerged and diphasic fermentation technologies are the principal methods available for the production of fungal biomass. Optimization of fermentation systems depends on a multitude of factors such as growth medium, physico-chemical conditions and type of seed inoculum. Fermentation processes should be selected or manipulated to trigger the production of stable, durable and virulent propagules. Spores produced in submerged fermentation are known to be more sensitive, unstable and less virulent than propagules produced in an aerial environment. The production and formulation of mycelial biomass is often considered for fungi unable to sporulate in submerged fermentation. The composition and balance of the growth medium deserves great attention because it can markedly influence yield and the biological characteristics of fungi.
