TL;DR: A Semimechanistic mathematical model is developed which describes the growth of Rhizopus oligosporus in a model solid‐state fermentation system and provides an insight into the possible rate‐limiting steps in solid‐ state fermentation—the generation of glucose within the substrate and the resulting availability of glucose at the surface.
Abstract: A Semimechanistic mathematical model is developed which describes the growth of Rhizopus oligosporus in a model solid-state fermentation system. Equations are presented for the release of glucoamylase, the diffusion of glucoamylase, the hydrolysis of starch, the generation and diffusion of glucose, and the uptake of glucose and conversion into new biomass. Good agreement of the model with the experimental data was obtained only after the glucoamylase diffusivity and the maximum specific glucose uptake rate were altered from their originally determined values. The model recognizes the distributed nature of the solid-state fermentation and therefore is able to predict the concentration profiles of the system components within the substrate. The model provides an insight into the possible rate-limiting steps in solid-state fermentation-the generation of glucose within the substrate and the resulting availability of glucose at the surface.

TL;DR: Tea waste, supplemented with minerals, was used as the solid substrate for the synthesis of glucoamylase by a strain of Aspergillus niger NCIM 1248 to choose among different carbon sources and malt extract gave the highest enzyme titre.

TL;DR: The supplementation of basal medium with enriched peptone, oliveoil, and Tween-80 positively influenced both enzyme production and fungal growth.
Abstract: Lipase, protease, and amylase production by Penicillium restrictum in solid-state fermentation was investigated. The basal medium was an industrial waste of babassu oil (Orbignya oleifera) production. It was enriched with peptone, olive oil, and Tween-80. The supplementation positively influenced both enzyme production and fungal growth. Media enriched with Tween-80 provided the highest protease activity (8.6 U/g), whereas those enriched with peptone and olive oil led to the highest lipase (27.8 U/g) and amylase (31.8 U/g) activities, respectively.

TL;DR: Aspergillus niger V 22 B 35, a wild strain, was found to produce 4 times more pectinase than the reference strain, and the screening involved three simple and rapid steps.
Abstract: Screening of 248 cultures, isolatcd from Mexico's coffee growing areas, was carried out to select potent culture for production of pectinase from coffee pulp by solid state fermentation. A pectolytic strain of Aspergillus mer CH 4 was used as reference to evaluate the potential of the wild strains. The screening involved three simple and rapid steps. The first step involved the qualitative evaluation of pectolytic activities of 248 fungal strains on a selective solid agar medium, while the second one consisted of the quanlification of the pectolytic activities of selected 13 isolates in a submerged fermentation medium, with pectin as the sole carbon source. The third step involved the assay of four selected fungal isolates for their capacity to produce pectinase from coffee pulp by solid state fermentation. Aspergillus niger V 22 B 35, a wild strain, was found to produce 4 times more pectinase than the reference strain.
