TL;DR: The use of low-cost substrates to produce Trichoderma spores was evaluated in this article, where Rice, corn bran, and wheat bran were used as a solid substrate to grow Trichodorma harzanium sp., Trichoderm viride sp, Tricho- derma koningii sp., and Trichodesporum polysporum sp.
Abstract: In the present work, the use of low-cost substrates to produce Trichoderma spores was evaluated. Rice, corn bran, and wheat bran were used as solid substrate to grow Trichoderma harzanium sp., Trichoderma viride sp., Tricho- derma koningii sp., and Trichoderma polysporum sp. No external nutrient sources were added to the solid substrate that was only moisturized with deonized water, sterilized, inoculated, and cultivated at 30 °C for 7 days. Wheat bran showed to be the most suitable substrate to produce Trichoderma spores for all strains that were evaluated. High spore counts were obtained for T. harzianum sp. (28.30×10 8 /gds) and T. viride sp. (24.10×10 8 spores/gds).

TL;DR: Recent advances in laccase production technology are reviewed, with focus on the following areas: characteristics and advantages of lignocellulosic agricultural wastes used as SSF substrates of lAccase production, and detailed suggestions for the selection of lignelectric agricultural wastes.
Abstract: Laccases are copper-containing oxidase enzymes found in many fungi. They have received increasing research attention because of their broad substrate specificity and applicability in industrial processes, such as pulp delignification, textile bleaching, phenolic removal, and biosensors. In comparison with traditional submerged fermentation (SF), solid-state fermentation (SSF) is a simpler technique for laccase production and has many advantages, including higher productivity, efficiency, and enzyme stability as well as reduced production costs and environmental pollution. Here, we review recent advances in laccase production technology, with focus on the following areas: (i) Characteristics and advantages of lignocellulosic agricultural wastes used as SSF substrates of laccase production, including detailed suggestions for the selection of lignocellulosic agricultural wastes; (ii) Comparison of fungal laccase production from lignocellulosic substrates by either SSF or SF; (iii) Fungal performance and strain screening in laccase production from lignocellulosic agricultural wastes by SSF; (iv) Applications of laccase production under SSF; and (v) Suggestions and avenues for future studies of laccase production by fungal SSF with lignocellulosic materials and its applications.

TL;DR: In this paper, the authors studied the production of extracellular lipases by solid state fermentation in soybean meal with different supplements and found that the medium with urea and soybean oil significantly increased enzyme production for all studied pH and microorganisms.
Abstract: The aim of this work was to study the production of extracellular lipases by solid state fermentation in soybean meal with different supplements. Lipase production by two microorganisms, screened by their potential for lipase production, was followed in terms of hydrolytic activity at different pH values(4, 7 and 9). The supplementation of the medium with urea and soybean oil significantly increased the enzyme production for all studied pH and microorganisms. Microorganism Penicillium P58 and P74 showed the possibility of production of different lipases with alkaline and acidic characteristics. In soybean meal supplemented with urea and soybean oil, this microorganism yielded 139.2 and 140.7U lipase/g of dry substrate in 48 h of fermentation, in alkaline and acidic conditions, respectively. Different behavior was observed when the enzyme extract was evaluated in neutral conditions, which yielded 180.0U lipase/g in 72 h. A new promising lipase producer strain was testedon soybean meal with different supplements. The strain produced a lipase with high activities by solid state fermentation of soybean meal supplemented with urea and soybean oil.

TL;DR: The highest milk-clotting activity (MCA) was at pH 5.7, at 70°C and in 0.04 M CaCl2; it was stable in the pH range 3.5-4.5 for 24h and up to 45°C for 1h as discussed by the authors.
