Optimization of Extracellular Cellulase Production by Trichoderma harzianum
ABSTRACT Background and Objectives: Cellulose is a major component of plant biomass, which can be converted into biofuels and valuable chemicals. The key step in utilization of this organic material is its hydrolysis into soluble sugars. This study evaluated cellulase production by Trichoderma harzianum under different pH values, temperatures and incubation...
متن کاملTreatment of Dairy Wastewater Using Pilot Scale Tricking Filter
A pilot scale trickling filter and secondary sedimentation are used to evaluate the feasibility of this process for the treatment of raw dairy waste. The BOD in the raw waste of 252 to 1200 mg/l is reduced 50-73% by a single stage and a further 17-55% by sedimentation tank. Treatment efficiencies are determined at various waste strengths and influent flow rates. With a loading rate of 5-12 kg B...
متن کاملProduction of recombinant proteins in microalgae at pilot greenhouse scale.
Recombinant protein production in microalgae chloroplasts can provide correctly folded proteins in significant quantities and potentially inexpensive costs compared to other heterologous protein production platforms. The best results have been achieved by using the psbA promoter and 5' untranslated region (UTR) to drive the expression of heterologous genes in a psbA-deficient, non-photosyntheti...
متن کاملOptimization of cellulase production by Penicillium sp.
The production of cellulolytic enzymes (β-exoglucanase, β-endoglucanase and β-glucosidase) by Penicillium sp. on three different media in liquid shake culture conditions was compared. The organism exhibited relatively highest activity of endoglucanase among three enzymes measured at 7-day interval during the course of its growth on Czapek-Dox medium supplemented with 0.5 % (w/v) cellulose. Cell...
متن کاملLarge-scale production of a thermostable Rhodothermus marinus cellulase by heterologous secretion from Streptomyces lividans
BACKGROUND The gene encoding a thermostable cellulase of family 12 was previously isolated from a Rhodothermus marinus through functional screening. CelA is a protein of 260 aminoacyl residues with a 28-residue amino-terminal signal peptide. Mature CelA was poorly synthesized in some Escherichia coli strains and not at all in others. Here we present an alternative approach for its heterologous ...
