چکیده

The production of a notable and highly effective pectinase and cellulase, by the commercial baker’s yeast Saccharomyces cervisiae utilizing potato processing wastes, was achieved in 5-day solid state fermentation (SSF) cultures, at temperature 25 °C, pH range 4.0-5.0 and additive of ferric chloride. Pectinase and cellulase activities were stimulated by using potato wastes supplemented with urea, as the sole carbon and nitrogen sources, resulted in 70.20 and 98.85 % reduction of viscosity. It is concluded that citric acid production from pectinolytic and celluolytic Saccharomyces cervisiae optimization with Aspergillus niger MAF3, maximally 46.67 and 68.44 g/kilogram solid potato wastes.

Bio-ethanol production through simultaneous saccharification and co-fermentation (SSCF) of a low-moisture anhydrous ammonia (LMAA)-pretreated napiegrass (Pennisetum purpureum Schumach)

Efficient bio-ethanol production from napiegrass (Pennisetum purpureum Schumach) was investigated. A low-moisture anhydrous ammonia (LMAA)-pretreated napiegrass was subjected to simultaneous saccharification and co-fermentation (SSCF), which was performed at 36°C using Escherichia coli KO11, Saccharomyces cerevisiae, cellulase, and xylanase. It was found that use of xylanase as well as the LMAA...

A thermophilic strain AMF-07, hydrolyzing carboxymethylcellulose (CMC) was isolated from Kerman hot spring and was identified as Bacillus licheniformis based on 16S rRNA sequence homology. The carboxymethylcellulase (CMCase) enzyme produced by the B. licheniformis was purified by (NH4)2SO4 precipitation, ion exchange and gel filtration chromatography. The purified enzyme gave a single band on S...
