Direct Bio-Utilization of Untreated Rapeseed Meal for Effective Iturin A Production by Bacillus subtilis in Submerged Fermentation
The feasibility of using untreated rapeseed meal as a nitrogen source for iturin A production by Bacillus subtilis 3-10 in submerged fermentation was first evaluated by comparison with two different commercial nitrogen sources of peptone and ammonium nitrate. A significant promoting effect of rapeseed meal on iturin A production was observed and the maximum iturin A concentration of 0.60 g/L wa...
متن کاملENDOGLUCANASE PRODUCTION BY Bacillus amyloliquefaciens USING COFFEE PULP AS SUBSTRATE IN SOLID STATE FERMENTATION
In this study, endoglucanase was produced from coffee pulp waste by Bacillus amyloliquefaciens MTCC610. The effects of the fermentation parameters such as pH, temperature, and the carbon source sucrose with different percentages (2% -10%) were used in coffee pulp substrate. The endoglucanase production was assayed using carboxymethyl cellulose (CMC) as the carbon source. B. amyloliquefaciens MT...
متن کاملAmylase production from Aspergillus oryzae LS1 by solid-state fermentation and its use for the hydrolysis of wheat flour
Nine Aspergillus and three of Trichoderma strains were grown on wheat bran (WB) medium under solid state fermentation (SSF) for amylase production. Aspergillus oryzae LS1 produced the highest level of the enzyme. The thermal stability profile of its crude enzyme revealed the half-life time of more than 2 h at 50 and 60ºC. The enzyme production was affected by strain type, incubation periods, le...
متن کاملEvaluation of HPLC and MEKC methods for the analysis of lipopeptide antibiotic iturin A produced by Bacillus amyloliquefaciens
Two methods, high-performance liquid chromatography (HPLC) and micellar electrokinetic chromatography (MEKC), for analysis of multicomponent lipopeptide antibiotic iturin A are described. After conducting a series of optimizations, the HPLC separation of iturin A2, A3, A4, A5, A6, A7, and A8 isomers were achieved by a NPS RP-C18 column with an isocratic elution of acetonitrile/10 mM ammonium ac...
متن کاملProduction and biochemical characterization of a thermostable phytase from Bacillus amyloliquefaciens LOR10
Phytase can improve the nutritional value of plant-based foods by enhancing protein digestibility and mineral availability through phytate digestion in the stomach and the food processing industry. Microbial sources are more promising for the production of phytases on a commercial scale. The objectives of this exploration were to screening and isolation of phytase-producing bacteria from hot sp...
