Fermentation of agricultural wastes by yeast

Solid state fermentation of agricultural wastes for endoglucanase production

The lignocellulosic biomass (especially agricultural wastes) is known to be an excellent carbon source for microbial enzyme production. In this paper, the cellulase production from lignocellulosic materials under solid state fermentation (SSF) was investigated. The effects of fermentation conditions, such as moisture content, initial pH, temperature, and composition of mixed substrate (wheat st...

Pectinase Production by Penicillium Viridicatum Rfc3 by Solid State Fermentation Using Agricultural Wastes and Agro-industrial By-products

Pectin lyase and polygalacturonase production by newly isolated Penicillium viridicatum strain Rfc3 was carried out by means of solid state fermentation using orange bagasse, corn tegument, wheat bran and mango and banana peels as carbon sources. The maximal activity value of polygalacturonase (Pg) (30U.g) was obtained using wheat bran as carbon source while maximal pectin lyase (Pl) (2000 U.g)...

Solid-phase Methane Fermentation of Solid Wastes

Dr. Ghosh has presented a novel technique for the con­ version of Municipal Waste (MSW) to methane rich gas. Prior work has either permitted fermentation to proceed naturally (landfill gas extraction) or used conventional stirred reactors (DOE Ref COM facility). Proposed is to recycle leachate through a mass of solid waste to achieve volatile acids and then to convert the acids to methane in a ...

Windrow composting of agricultural and municipal wastes

Kuhlman, L.R., 1990. Window composting of agricultural and municipal wastes. Eur. Symp. on Integrated Resource Recovery from Municipal Solid Wastes. Resour. Conserv. Recycl., 4: 1 5 1 160. Many wastes are produced from agricultural and municipal facilities that are not suitable for direct land application. Composting these wastes converts them to a humus-containing organic material advantageous...
