this experiment aimed to investigate the effect of (zero, 20, 40 and 60 mg/kg atriplex forage) malva sylvestris on digestibility and microbial fermentation of atriplex in one-humped camel. fermentation parameters by gas production technique and in vitro digestibility by two-stage digestion were measured by two years old female fistulated camels. addition 40 and 60 mg/kg malva sylvestris increas...

low density polyethylene films incorporating different types of organically modified nanoclays were prepared. physical, surface morphology and mechanical properties of the films were analyzed by x-ray diffraction pattern, scanning electron microscopy and tensile strength (ts) and length increase until fracture point (e) parameters, respectively. colony counting method was used to investigate an...

BACKGROUND Using treated wastewater in agriculture irrigation could be a realistic solution for the shortage of fresh water in Iran, however, it is associated with environmental and health threats; therefore, effluent quality assessment is quite necessary before use. The present study aimed to evaluate the physicochemical and microbial quality of Shiraz wastewater treatment plant effluent for b...

this experiment was conducted to determine the effect of procceesing of sugarcane pith with high pressure steam (210-220c◦, at 19 bar, over 3 min, on 70 % moisture) on fermentative activity and gas production parameters and degradation by pure microorganism of rumen. the microbial different groups of rumen were separated by physical and chemical methods and using antibiotics. these microbial gr...

Stimulating in situ microbial communities in oil reservoirs to produce natural gas is a potentially viable strategy for recovering additional fossil fuel resources following traditional recovery operations. Little is known about what geochemical parameters drive microbial population dynamics in biodegraded, methanogenic oil reservoirs. We investigated if microbial community structure was signif...

Hyperbaric storage (HS), storage under pressure at 25°C and 30°C, of a ready-to-eat (RTE) soup was studied and compared with refrigeration. Soup was stored at different time (4 and 8 h), temperature (4°C, 25°C, and 30°C), and pressure (0.1, 100, and 150 MPa) conditions, to compare microbial loads and physicochemical parameters. HS resulted in similar (microbial growth inhibition) to better (mic...

Multidimensional gradients of inorganic compounds influence microbial activity in diverse pristine and anthropogenically perturbed environments. Here, we suggest that high-throughput cultivation and genetics can be systematically applied to generate quantitative models linking gene function, microbial community activity, and geochemical parameters. Metal resistance determinants represent a uniq...

Biodiscovery from microbial resources can be defined as the exploration of microbial metabolic products to detect, identify and evaluate their potential for medicinal, agricultural and biotechnological operations. Microbial resource centres house microbial compounds produced under different physical and nutritional parameters to maximise the production of metabolites and are subsequently tested...
