Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Sixteen different mould cultures viz. Aspergillus, Alternaria, Arthroderma, Trichoderma, Fusarium, Penicillium, Rhizopus and Chochliobolus were isolated from the soil samples collected from different localities of Doha (Qatar) by serial dilution method. The preliminary screening of isolates was done by selecting initial colonies showing relatively bigger zones of starch hydrolysis on nutrient agar medium by pour plate method. The isolates were then subjected to secondary screening by submerged fermentation. The product yield was analyzed in dependence of mycelial morphology, biomass level and protein contents. On the basis of kinetic variables, notably A. oryzae IIB-6 was found to be a hyper producer of GGH compared to A. kawachii IIB-2. A noticeable enhancement in enzyme activity of over 30% was observed when process parameters were further optimized using a 2-factorial Plackett-Burman design. The model terms were found to be highly significant (HS, p 0.05), indicating the potential utility of the culture (dof~3). 88 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Six different agro-industrial waste residues (rice straw, rice bran, corn flakes, wheat bran, wheat flakes, and grinded wheat kernel) were procured from the local market. These substrates (10 g) were moistened (1:1) with different moistening agents (distilled water, tap water, mineral salts solution (FeSO4.7H2O 0.02, MgSO4.7H2O 1.0, (NH4)2SO4 4.0, KH2PO4 0.6, K2HPO4 1.4 mg/gds at pH 5), 0.1 N HCl, sodium acetate buffer (pH 5.5), sodium phosphate buffer pH 7.5) and screened for the production of 1,4- - D-glucan glucohydrolase for 96 hours in static cultures. The substrate and moistening agent that gave maximum enzyme production were selected and their fermentation conditions were further optimized. The levels of selected solid substrate, moistening agent and fermentation conditions such as pH, temperature, time of incubation, inoculum size etc. were optimized by one variable at a time method. Aspergillus oryzae IIB-6 was found to be a good producer of 1,4- -D-glucan glucohydrolase in wheat bran medium containing mineral salts as an additional trace elements so that it can be used for biotechnological purposes. 92 pp. Englisch.
