The aim of this work was to utilize Red gram husk as a substrate for tannase production and optimize the Temperature and incubation period of tannase production in solid state fermentation. The maximum production of tannase was found to be 43 U/g/min at 35°C, incubated for 96 h. The tannin content in the substrate was decreased during incubation period. The tannase prepared from Aspergillus nig...

Enzymes are the most efficient bio-catalysts which catalyze many biological reactions. Enzymes are the most important products obtained for human needs through microbial sources. Enzymes are first reported in the second half of the nineteenth century (Godfrey et al. 1996). Since then, its usage has increased manifolds in various industries. In the last three decades with rapid strides in the fi...

The feasibility of producing antibiotics by single-stage continuous fermentation was explored by means of a specially designed pilot plant. Both the chloramphenicol and penicillin processes appeared adaptable to such an operation. At dilution rates of 1.0 and 0.5 volume changes per day respectively, yields of from & to 4 of the maxima obtained in batch operation were maintained in the steady-st...

Saccharomyces cerevisiae is a glucophilic yeast, preferring glucose to fructose. During fermentation, glucose is consumed at a higher rate than fructose, and the proportion of fructose increases as fermentation progresses. This can lead to imbalances in the wines, and under the stressful conditions found at the end of fermentation, make it more difficult for wine yeast to utilize this nonprefer...

A fungal strain of Aspergillus oryzae was used for the production of alpha amylase by solid state fermentation from agro-industrial waste. Enzyme production was growth associated and maximum activity (8.23 U/ml) were obtained after 120h when incubated at 30°C on wheat bran with initial moisture content 60%; initial medium pH = 5 . Enzyme activity increased when the solid medium was supplemented...

Research was conducted to study the effects of biphasic anaerobic fermentation upon an organic fraction of municipal solid waste, and to observe the fate of heavy metals and pathogenic organisms in the acidogenic and methanogenic environments of the biphasic process. The high-solids (16 wt % solids) substrate was packed in a bench-scale, anaerobic, solid-state fermenter with amounts of lead nit...

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...

Production of cold active lipase by semisolid state fermentation involves the use of agroindustrial residues. In the present study, semisolid state fermentation was carried out for the production of cold active lipase using Micrococcus roseus, isolated from soil samples of Gangotri glaciers, Western Himalayas. Among various substrate tested, groundnut oil cake (GOC) favored maximal yield of lip...

Solid-state fermentation (SSF) processes involve the growth of microorganisms (typically fungi) on a solid material in the absence or near absence of free-flowing water. The wide range of solid materials used in SSF can be classified into two great categories: inert (synthetic materials) and non-inert (organic materials). The former only acts as an attachment place for the fungus, whereas the l...
