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...

production of thermostable alkaline protease in tray bioreactor for solid state fermentation is a unique process which may lead to an economical approach for production of enzyme from agricultural waste or low cost substrate. in solid state fermentation using tray bioreactor, several agricultural residues such as rice bran, sugarcane bagasse, wheat bran, barely bran, corn meal and corn husk wer...

optimization of the fermentation medium for maximum alkaline protease production was carried out. fifteen positive isolates were examined for their extent of alkaline protease production. the most potent producer was identified as bacillus sp. the solid substrate screening showed that the combination of wheat straw and bean husk was the best one. the initial screening by using plackett–burman’s...

context:in this review, we discuss empirical and stoichiometric models, which have been developed recently in ssf processes and the influence of environmental conditions on the variables of these models. additionally, new studies on modeling of product formation are also mentioned. evidence acquisition:solid-state fermentation (ssf) is recognized as a cheap process for producing many valuable p...

N.sitophila was grown under controlled conditions of solid state and submerged fermentation on Sago hampas. The optimum conditions of protein enrichment previously established for sugar beet pulp was used for this study. Under this condition the protein content of Sago hampas under solid state increased from 1.4 to 14.45% (W/W) whereas for Sago hampas and Sago starch, the protein content under ...

A soft-sphere discrete particle model was used to simulate mixing behavior of solid substrate particles in a slow rotating drum for solid-state fermentation. In this approach, forces acting on and subsequent motion of individual particles can be predicted. The (2D) simulations are qualitatively and quantitatively validated by mixing experiments using video and image analysis techniques. It was ...

a solid state fermentation method was used to utilize wheat straw as substrates for citric acid production by using aspergillus niger atcc 9142. the plackett burman design (pbd) of experiments was used to test the relative importance of the variables affecting production such as moisture content, age of spore, inoculum size, initial ph of substrate, methanol concentration, incubation temperatur...

Production of total ergot alkaloids by Claviceps fusiformis in solid state fermentation was 3.9 times higher compared to that in submerged fermentation. Production was equal in the case of Claviceps purpurea but the spectra of alkaloids were advantageous with the use of solid state fermentation. The data establish potential of solid state fermentation which was not explored earlier for producti...

Due to the numerous applications of lipases in industry, there is a need to study their characteristics, because lipases obtained from different sources may present different properties. The aim of this work was to accomplish the partial characterization of lipases obtained through submerged fermentation and solid-state fermentation by two species of Aspergillus. Fungal strains were isolated fr...

The effect of Solid State Fermentation (SSF) on Chitosan production by A. niger was investigated. A. niger BBRC 20004 from Biochemical and Bioenvironmental Research Centre of Sharif University of Technology (Tehran, Iran), was grown on corn residue. Chitosan was extracted from the fungal mycelia using hot alkaline and acid treatment. A. niger was incubated for 12 days on corn residue with moist...
