The production of extra cellular lipase in Solid State Fermentation (SSF) using Yarrowia lipolytica NCIM 3589 with Palm Kernal cake (Elaeis guineensis) has been studied. Different parameters such as incubation time, inoculum level, initial moisture content, carbon level and nitrogen level of the medium were optimized. Screening of various process variables has been accomplished with the help of...

L-asparaginase (L-asparagine amido hydrolase, E.C.3.5.1.1) is a promising chemotherapeutic agent which plays a vital role in treatment of a variety of lymphoproliferative disorders, lymphosarcoma and acute lymphoblastic leukemia in particular. An attempt is made in the present study to optimize the production of L-asparaginase by Fusarium equiseti using soya bean meal under solid state fermenta...

Animal fleshing, the major proteinaceous solid waste generated from leather industry, was used as substrate for the production of alkaline protease by Bacillus cereus 1173900 in solid-state fermentation (SSF). Maximum protease activity of 12,310 U/g was observed at 60 h in SSF crude extract. The extracted protease enzyme was purified by 53.64-fold through ammonium sulphate precipitation and chr...

Soybean meal (SBM) is an important protein source in animal feed. However, the levels of SBM inclusion are restricted in some animal species by the presence of antinutritional factors (ANFs), including non-starch polysaccharides (NSPs) and α-galactosides (GOSs). The aim of this study was to reduce the soybean meal NSPs and GOSs by solid-state fermentation (SSF) using a combination of cellulolyt...

Two agro-industrial coproducts, soybean cotyledon fiber and distiller's dried grains with solubles (DDGS), were used as substrates to evaluate the effect of coculturing three different fungi, Aspergillus oryzae, Trichoderma reesei, and Phanerochaete chrysosporium, on enzyme production by solid-state fermentation (SSF). When soybean fiber was used as the substrate, a maximum xylanase activity of...

Chemical composition of Larrea tridentata leaves was determined and elevated content of lignin (35.96 % w/w) was found. The present study was proposed in order to evaluate the extraction of bioactive compounds, particularly phenolic compounds, by solid-state fermentation (SSF) of L. tridentata leaves. The basidiomycete Phanerochaete chrysosporium was used in the experiments due to its ability t...

Pectate lyase (PL) was produced by the filamentous fungus Penicillium viridicatum RFC3 in solid-state cultures of a mixture of orange bagasse and wheat bran (1 : 1 w/w), or orange bagasse, wheat bran and sugarcane bagasse (1 : 1 : 0.5 w/w), and in a submerged liquid culture with orange bagasse and wheat bran (3%) as the carbon source. PL production was highest (1,500 U mL(-1) or 300 Ug(-1) of s...

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 ...

a solid state fermentation method was developed for the production of citric acid from date pulp (obtained of date syrup production from the process) by aspergillus niger ptcc 5010. poor yield was obtained when potassium ferrocyanide treated date pulp were used as substrate, but methanol at a 3-4% concentration markedly increased the forma-tion of citric acid from the waste. the optimum range o...

Simultaneous saccharification and fermentation (SSF) of solid biomass can reduce the complexity and improve the economics of lignocellulosic ethanol production by consolidating process steps and reducing end-product inhibition of enzymes compared with separate hydrolysis and fermentation (SHF). However, a long-standing limitation of SSF has been too low ethanol yields at the high-solids loading...
