Some microorganisms among the bacteria and fungi have the potential for converting organic wastes with a high C:N ratio into animal feed with a high protein content at a rapid rate. Recent advances in the knowledge of basic physiology of those organisms have led to optimization and control of the environmental conditions, resulting in increased productivity from fermentations. Carbohydrate wastes, especially of agricultural origin, provide a plentiful and renewable resource for the production of microbial protein. Most of the wastes require a physical or chemical pretreatment for making them suitable for microbial fermentation. Higher productivity of microbial biomass is generally obtained in submerged fermentation than in solid state fermentation because the environment can be easily controlled in submerged systems. Further studies on the modification of controlled instrumented fermenters to suit the appropriate technology and development of inexpensive techniques for immobilization of cells to inert materials, will make microbial proteins a highly desirable feed for intensive aquaculture.
