TLDR
Solid state fermentation can be directly carried out with abundant low-cost biomaterials with minimal or no pretreatment, and thus is relatively simple, uses less energy than submerged fermentation (SmF), and can provide unique microenvironments conducive to microbial growth and metabolic activities.Abstract:
Publisher Summary This chapter reviews the recent advances in solid state fermentation (SSF) system research and development. SSF can be directly carried out with abundant low-cost biomaterials (starch, cellulose, lignin, hemicellulose, and chitin etc.) with minimal or no pretreatment, and thus is relatively simple, uses less energy than submerged fermentation (SmF), and can provide unique microenvironments conducive to microbial growth and metabolic activities. Organic acids and industrial enzymes are the two most common categories of products from SSF. With little or no free water in the fermentation bed, SSF generates higher volumetric productivity and less waste water. The extraction of products from the fermentation bed provides more concentrated solutions than submerged fermentation for the downstream processes. All the advantages of SSF suggest that SSF has a high potential as a much more economical industrial process. However, its industrial applications are very limited, especially in western countries. The main problem is that the development of a simple and practical automated fermenter for SSF processes has not yet been achieved. Traditionally, SSF is carried out in trays or packed-bed bioreactors. These conventional reactors are simple to construct and widely used, but cannot provide enough mass and heat transfer, which are very important for fermentation processes.read more

Agro-industrial wastes and their utilization using solid state fermentation: a review
TL;DR: The use of agro-industrial wastes as raw materials can help to reduce the production cost and also reduce the pollution load from the environment as mentioned in this paper, and these residues can be used as an alternate source for the production of different products like biogas, biofuel, mushroom, and tempeh as the raw material in various researches and industries.

Phytate and phytase: consequences for protein utilisation.
TL;DR: It appears that the relative solubilities of phytate salts and proteins from different feed ingredients and their effects on the extent of protein–phytate complex formation, coupled with variations in the effectiveness ofphytase in different dietary contexts, may be the major factors responsible.

TL;DR: A reaction–diffusion model is presented to try to explain why enzyme production in solid-state fermentation (SSF) is higher than in submerged fermentation (SmF) based on micrographic measurements of mycelial aggregates for each kind of fermentation system.
