This book was released on 2006 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABST ACT The use of waste as raw material is important for government economy and natural balance. The purpose of this work is to study the production of xylanase and CMCase enzyme by Aspergillus niger in solid state fermentation (SSF) using agricultural residues sugar cane bagasse as substrates. The study is focus on the effect of substrate concentration which is 1 g/L, 3g/L and 5 g/L. All the enzymes were incubating in temperature 37 oC and pH 5.0 for 30 minutes. The reaction was quenched by cooling on ice and the amount of reducing sugar was measured by dinitrosalicyclic (DNS) acid procedure with slight modification (Miller, 1965). The mixture was then incubated at 100 oC for 5 minutes. Subsequently, the reaction was stopped by cooling on ice. Distilled water was added into the final volume of 16 ml and the color intensity was measured at wavelength of 575 nm. The concentration of SCB affected the xylanase and CMCase activity. Xylanase and carboxymethylcellulase activity was higher at lower concentration hen using 3 g of SCB.

This book was released on 2012-04 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microorganisms bring about most of the cellulose degradation occurring in nature. In the present study, optimization for cellulase production by Aspergillus niger was investigated by using paddy straw as substrate.Cellulase enzyme was produced by the fungus extracellularly. Optimization of cellulase production was done by using various physical (Temperature, pH, Salinity and Incubation time) and chemical parameters (Carbon sources and nitrogen sources) which could influence the enzyme activity. Cellulase production was maximum at the temperature 20°C and minimum at 40ºC. The optimal pH for the cellulase production was observed maximum in 6.0 and minimum in 7.0. Cellulase production was maximum at 48 hours and minimum at 24 hours. Cellulase production was maximum with when fructose was used as a carbon source and minimum with sucrose. Cellulase production was maximum when Malt extract was used as a nitrogen source and minimum with yeast extract. The cellulase enzyme extract was partially purified and its protein fraction was stained with its molecular weight determination by using SDS-PAGE. It revealed two protein bands with the molecular weights of about 83 kD and 50kD.

Available in PDF, EPUB and Kindle. Book excerpt: G.HAINNAUX Departement Milieu et Activites Agricoles, Centre ORSTOM, 911 Avenue d' Agropolis, B.P. 5045, 34032 Montpellier Cedex , France. Solid state fermentation, popularly abbreviated as SSF, is currently investigated by many groups throughout the world. The study of this technique was largely neglected in the past in European and Western countries and there is now a high demand for SSF, meaning in food, environment, agricultural, phannaceutical and many other biotechnological applications. It gives me satisfaction to note that the importance of this technique was realised at my department way back in 1975 since then, our team has put concentrated efforts on developing this technique. xvii Foreword Advances in Solid State Fermentation Foreword M. PUYGRENIER Agropolis Valorisation, Avenue d' Agropolis, 34394 Montpellier Cedex 5, France. On the name of the Scientific Community, I would like to express the wish that this International Symposium on SSF should be successful. Solid State Fermentation is part of biotechnology research. It consists on seeding solid culture medium with bacteria or fungi (filamentous or higher) and on producing, in this medium (solid components and exudates) metabolites and high value products. In fact, this process is very old. In older industries such the food and agricultural, this technique has been extensively used. An example of this is the production of pork sausages and Roquefort cheese. Pharmaceutical industry could make extensive use of SSF in the production of secondary metabolites of many kinds and development in this direction is soon expected.

Download or read book Solid State Fermentation of Rice Straw for Production of Cellulases by Selected Fungi written by Md. Munir Hayet Khan and published by . This book was released on 2007 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of cellulases from rice straw (RS) by four fungi: Trichoderma harzianum (ScahmT105), Trichoderma spp.(1) (STP101), Trichoderma spp.(3) (STP103) and Phanerochaete chrysosporium was investigated. The microbial treatment using solid state fermentation was conducted in 250 ml Erlenmeyer flasks considering ride straw as a major solid substrate. The highest cellulase activities such as 25.53 U/g rice straw due to filter paper activity and 42.86 U/g of rice straw due to carboxymethyl cellulose activity were obtained at day 4 of cultivation using Phanerochaete chrysosporium for the purpose of selecting the best fungus among these four strains. Glucusoamine for growth and reducing sugar as substrate utilization indicator were observed to evaluate the fermentation of rice straw in the experiment and pH values were recorded as well. Four process parameters of the solid state fermentation namely moisture content, mineral content, co-substrate and inoculum size with three levels of each parameter were used to optimize the production of cellulase by Plackett-Burman technique under factorial design. The results for first phase of optimization showed that the production of cellulase were higher i.e. 26.43 U/g of rice straw due to filter paper of activity and 46.25 U/g of rice straw due to carboxymethyl cellulose activity compared to the production obtained during the earlier study of selecting best strain among four fungi but the optimum regions of the surfaces was not found. Second phase of optimization was conducted to determine the actual optimum condition within the ranges of variables tested. The experimental data were used to develop second order polynomial models considering linear, quadratic and interaction effects of the variables (factors). The optimum values obtained at second phase of optimization for moisture content, inoculum size, co-substrate and mineral content were 50% (v/w), 10% (v/w), 1% (w/w) and 5% (v/w) respectively. Using the final model equations the process factors/variables were tested by increasing or decreasing the values within the ranges of parameters tested and optimum production of cellulase were obtained to be 30.18 U/g of rice straw (FPU) and 53.93 U/g of rice straw (CMCase) for Phanerochaete chrysosporium with the optimum process conditions. A final experiment with these optimum process conditions. A final experiment with these optimum process parameters of SSF was conducted to evaluate the production of cellulases as well as the validation of the models which indicated the production of 29.46 U/g of rice straw due to filter paper activity and 54.83 U/g of rice straw due to carboxymethyl cellulose activity in the laboratory which approved the optimum production obtained with 2.4% and 1.6% error, respectively.
