Sporotrichum thermophile Growth, Cellulose Degradation, and Cellulase Activity.
The activity of components of the extracellular cellulase system of the thermophilic fungus Sporotrichum thermophile showed appreciable differences between strains; beta-glucosidase (EC 3.2.1.21) was the most variable component. Although its endoglucanase (EC 3.2.1.4) and exoglucanase (EC 3.2.1.91) activities were markedly lower, S. thermophile degraded cellulose faster than Trichoderma reesei....

the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
Extracellular nuclease from a thermophile, Streptomyces thermonitrificans: purification and characterization of the deoxyribonuclease activity.
An extracellular nuclease from Streptomyces thermonitrificans (designated as nuclease Stn alpha) was purified to homogeneity with an overall yield of 2.8%. The Mr of the purified enzyme was 39.6 kDa. The purified enzyme showed an exclusive requirement of Mn2+ for its activity but is not a metalloprotein. The optimum pH for ds- and ssDNA hydrolysis were 7.0 and 7.5 whereas, the optimum temperatu...

the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
Purification and characterization of an acidic, thermophilic phytase from a newly isolated Geobacillus stearothermophilus strain DM12
Microbial phytases were applied mainly to animal and human foodstuffs in order to improvemineral bioavailability and food processing. In addition, phytases have potentialbiotechnological application in various other fields, such as environmental protection,aquaculture and agriculture. Bacillus sp. DM12, an isolate from a hot spring, produces phytase,which catalyzes the hydrolysis of phytic acid...
