The objectives of the present study were isolation, identification, and characterization of xylanase producing actinomycetes, optimization of medium composition and cultural conditions for xylanase production, production using cheaper sources and extraction of extra cellular xylanase from a potential strain. Streptomyces hygroscopicus was selected and optimized for xylanase production in solid ...

Fermentation is one of the industrially important processes for the development of microbial metabolites that has immense applications in various fields. This has prompted to employ fermentation as a major technique in the production of phytase from microbial source. In this study, a comparison was made between submerged (SmF) and solid-state fermentations (SSF) for the production of phytase fr...

Cellulase production was carried out in solid-state fermentation using the waste from the vinegar industry as the substrate for Trichoderma koningii AS3.4262. This waste is porous and easy to degrade by cellulolytic fungi. The effects of water content, initial pH value in solid substrate and culture temperature on cellulase synthesis were observed for optimal production in flask fermentors. An ...

In this study, Glucoamylase production by Aspergillus niger was investigated under solid state fermentation using low cost by-products of agricultural processes as substrate. Highest enzyme production was observed when a combination of wheat bran (WB) and corn flour (CF) was used as compared to WB+ rice bran, WB+ rice flour and WB alone. Several compositions of corn flours were experimented. Th...

Large amount of wastes is generated every year from the industrial processing of agricultural raw materials. Most of these wastes are used as animal feed or burned as alternative for elimination. However, such wastes usually have a composition rich in sugars, minerals and proteins, and therefore, they should not be considered “wastes” but raw materials for other industrial processes. The presen...

Laccases are oxidative enzymes related to the degradation of phenolic compounds, including lignin units, with concomitant reduction of oxygen to water. Delignification is a necessary pretreatment step in the process of converting plant biomass into fermentable sugars. The objective of this work was to optimize the production of laccases and to evaluate the delignification of sugarcane bagasse b...

Dietary fiber (DF) has attracted increasing interest from nutritionists. The yield of DF by traditional extraction methods, however, is very low. This paper aims to increase the yield of DF by solid state fermentation using the edible and medicinal fungus Schizophyllum commune. Sweet potato residue (SPR) was selected as raw material for producing DF. Results showed that SPR was a good feedstock...

Previously, we have reported a novel bioethanol production system based on solid-state fermentation (SSF) and forage rice, which is used in silage-making process. In this study, evaluated the productivity of valuable materials via SSF using various plant other than rice. Italian ryegrass, sorghum, cassava, are also promising for SSF. Laboratory-scale experiments raw ryegrass yielded maximum 99 ...
