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...

Pathophysiological changes in the mouth of patients with diabetes mellitus (DM) predispose to overgrowth of Candida albicans. Various virulence factors such as proteinase and phospholipase production are involved in the process of degradation of the host cell membrane. These enzymes are involved in binding Candida species, especially in the hyphae stage, to the target tissue. In this study, the...

Saline rhizospheric areas are untouched environments for isolating actinomycetes with the potential of valuable salt tolerant enzyme production. In this study, we isolated and evaluated a total number of of 26 actinomycete strains from plant rhizosphere of the periphery of Dasht-e-Kavir desert. Isolated actinomycetes produced different enzymes. Among them 50, 46, 39, 27, 10 and 7 % of the isola...

IIn this study, the effect of different levels of Scrophularia striata extract on the parameters of laboratory gas production, the concentration of volatile fatty acids and the activity of hydrolytic enzymes on the contents of the cecum of adult male rabbits were investigated. For this purpose, 20 New Zealand rabbits weighing approximately 1.6 ± 0.2 kg (5 months and up) were used in a completel...
