Cost-effective lignocellulolytic enzyme production by Trichoderma reesei on a cane molasses medium
BACKGROUND Cane molasses, an important residue of the sugar industry, have the potential as a cost-effective carbon source that could serve as nutrients for industrial enzyme-producing microorganisms, especially filamentous fungi. However, the enzyme mixtures produced in such a complex medium are poorly characterized. In this study, the secretome of Trichoderma reesei grown on a cane molasses m...
متن کاملDevelopment of an ideal starch saccharification process using amylolytic enzymes from thermophiles.
The extensive efforts to screen thermophilic fungi and bacteria, isolated from various environmental samples, have resulted in the selection of Thermomucor indicae-seudaticae, Geobacillus thermoleovorans NP33 and G. thermoleovorans NP54 for the production of glucoamylase, amylopullulanase and alpha-amylase, respectively. Submerged and solid-state fermentation processes were optimized for maximi...
متن کاملAlcohol Production from Cassava Starch by Co-immobilized Zymomonas mobilis and Immobilized Glucoamylase
Simultaneous saccharification and fermentation of dextrin£zed cassava starch to glucose and alcohol, respectively, were carried out by co-immobilized Zymomonas mobilis and immobilz'zed glucoamylase (IG). Calcium alginate-entrapped cells and IG (4 : 1 ratio) gave an alcohol productivity of 0.30 glgww cellslh in a batchfermentation process. For continuous fermentation, 54.3 gil alcohol was produc...
متن کاملoptimal medium composition to enhance poly-β-hydroxybutyrate production by ralstonia eutropha using cane molasses as sole carbon source
in order to reduce the costs associated with poly-β-hydroxybutyrate production, growth and poly-β-hydroxybutyrate production of ralstonia eutropha were studied in batch culture on different carbon sources. experiments were designed and conducted to not only lower the cost of poly-β-hydroxybutyrate production by using inexpensive substrates, but also to increase poly-β-hydroxybutyrate production...
متن کاملL-tryptophan production by Escherichia coli in the presence of Iranian cane molasses
The essential amino acid L-tryptophan (Trp) has importance as a pharmaceutical agent, especially in neuro-medicine. It is also added to feed products as a food fortifier. Furthermore, application of Trp is widespread in biotechnology. Trp is produced by a condensation reaction between indole and Lserine, which is catalyzed by bacterial tryptophanase activity. In this study, we have investigated...
