TL;DR: This work summarizes the diversity of applications of solid state fermentation to valorize biomass regarding alternative energy and environmental purposes and presents an exhaustive number of microorganisms able to grow in a solid matrix.
Abstract: Solid state fermentation is currently used in a range of applications including classical applications, such as enzyme or antibiotic production, recently developed products, such as bioactive compounds and organic acids, new trends regarding bioethanol and biodiesel as sources of alternative energy, and biosurfactant molecules with environmental purposes of valorising unexploited biomass. This work summarizes the diversity of applications of solid state fermentation to valorize biomass regarding alternative energy and environmental purposes. The success of applying solid state fermentation to a specific process is affected by the nature of specific microorganisms and substrates. An exhaustive number of microorganisms able to grow in a solid matrix are presented, including fungus such as Aspergillus or Penicillum for antibiotics, Rhizopus for bioactive compounds, Mortierella for biodiesel to bacteria, Bacillus for biosurfactant production, or yeast for bioethanol.

TL;DR: Solid state fermentation was employed using Rhizopus oligosporus to develop a fermented product from rapeseed meal (RSM) and may open a new prospective for a simple and cost effective technique for reduction of toxicants in RSM.

TL;DR: In this article, Aspergillus flavipes BICC 5174 was used for the production of lovastatin by solid state fermentation (SSF) using different solid substrates such as wheat bran, bagasse, barley, soybean meal, gram bran and fruits waste and some of their combinations were tested for Lovastatin production.

TL;DR: In this article, the production of laccase by an indigenous strain of Pleurotus ostreatus HP-1 on solid state fermentation was studied on a wheat straw substrate with five agar plugs as the inoculum.
Abstract: The production of laccase by an indigenous strain of Pleurotus ostreatus HP-1 was studied on solid state fermentation. Culture parameters such as type and concentration of substrate, inoculum size, moisture content, pH, surfactant presence, temperature, and nitrogen source were optimized by conventional “one factor at a time” methodology. A maximum laccase yield of 3952 U g-1 of dry substrate optimized was obtained with wheat straw as substrate with five agar plugs as the inoculum, 60% moisture content, pH 5.0, surfactant concentration 0.015 gl-1, and nitrogen source (combination of L-asparagine and NH4NO3 at 10 mM concentration each) at incubation temperature 28oC. Enhancement in laccase activity was achieved with the use of various aromatic inducers and copper sulphate. Highest laccase activity of 14189 U g-1 of dry substrate was achieved using 0.28 mM copper sulphate under optimized conditions. Thus, the indigenous isolate seems to be a potential producer of laccase using SSF and can be exploited for further biotechnological applications. The process also promises economic utilization and value addition of agro-residues.

TL;DR: In this paper, the authors investigated lipase production and partial characterization of the crude enzymatic extracts obtained by Penicillium verrucosum using soybean bran as substrate.
Abstract: Current studies about lipase production by solid-state fermentation involve the use of agro-industrial residues towards developing cost-effective systems directed to large-scale commercialization of enzyme-catalyzed processes. In this work, lipase production and partial characterization of the crude enzymatic extracts obtained by Penicillium verrucosum using soybean bran as substrate was investigated. Different inductors were evaluated and the results showed that there is no influence of this variable on the lipase production, while temperature and initial moisture were the main factors that affected enzyme production. The optimized cultivation temperature (27.5 °C) and initial moisture of substrate (55%) were determined using the response surface methodology. Kinetics of lipase production was followed at the optimized growth conditions. Optimum lipase yield was 40 U/g of dry bran. The crude enzymatic extract showed optimal activity in the range from 30 to 45 °C and in pH 7.0.
