Solid-state fermentation (SSF) of vinegar wastes saves environmental resources and helps to recover valuable material for lignocellulose purposes. The development of solid-state fermentation technology is very important for the production of cellulase and ultimately for utilization of natural cellulose. However, inadequate dissipation of heat generated by biological activities has prevented sol...

 Central composite orthogonal design was applied to quantify relations  of xylanase production, loss of dry matter and change of pH with four critical variables during solid state fermentation of a mixture of wheat bran and wheat straw on which Aspergillus niger CCUG 33991 was cultivated. The studied variables included the percentage of wheat straw, temperature, moisture content, and fermentati...

in this study the effect of different nitrogen source substrates on the amount of chitosan production by aspergillus niger was investigated. a. niger ptcc 5012 from the persian type culture collection (ptcc) was grown on soy bean, corn seed and canola residues at 30 °c for specified cultivation days under sterilized conditions. chitosan was extracted from the fungal mycelia using hot alkaline a...

sesame oil cake (ssc) was bio-processed through solid state fermentation (ssf) under optimized conditions by a phytase-producing fish gut bacterium, bacillus subtilis subsp. subtilis (jx292128). ssf significantly reduced anti-nutritional factors (e.g., phytic acid, tannins and trypsin inhibitor) and crude fibre, while enhanced free amino acids, fatty acids and different minerals. phytase product...

background and objective: glucoamylase is a potent starch degrading enzyme whose cheap production has been an area of research. its production by aspergillus niger in solid-state fermentation was studied using dried garden pea peel as a substrate, which enormously reduced the production cost. the current study intended to produce glucoamylase by a cost-effective strategy and exhaustively charac...

Production of different pectinolytic enzymes was attempted using the actinomycete strain Streptomyces lydicus in submerged fermentation. Polygalacturonase and pectin lyase activities were detected in the culture supernatant, but the strain was not able to produce pectin esterase. Polygalacturonase production was studied in submerged, slurry-state and solid-state fermentation systems. All the ex...

Solid state fermentation (SSF) is a bioconversion process by microorganism and enzymes. It effectively depolymerizes the cellulose, ligno cellulose present in the agricultural produces, cereals and biomas. It also enriches protein, colour, antioxidant activity, modification of functional properties of cereals. Solid state fermentation provides wide range of application in food and bio processin...

different control strategies of bed temperature and moisture were investigated using various inlet air temperatures and air fluxes in both the ordinary packed bed bioreactor (without cooling water in the jacket) and the bioreactor with cooling water in jacket. the experiments were carried out within a 1-l solid-state packed bed bioreactor in which aspergillus niger was cultivated on wheat bran....

Polyhydroxyalkanoates are biopolyesters stored as reserve source of energy by a great number of prokaryotes. It is stored as intracellular granules and during normal growth, its content in the cells usually does not reach high concentrations, usually in the range of 2–10 %, but the PHB contents can reach more than 80 % of the dry biomass if growth is limited by depletion of an essential nutriti...
