During the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. In this study, the antibacterial activity of methanolic extract of T. pubescens (rich i...

Livestock grazing is one of the most important factors influencing the above-ground community composition and structure in a natural grassland ecosystem. Different grazing intensities also have the potential to alter soil C and N storage substantially in grasslands. We conducted a field community study and soil analyses to determine the effects of different grazing intensities on the above-grou...

Bacteria present in natural environments such as soil have evolved multiple strategies to escape predation. We report that natural isolates of Enterobacteriaceae that actively hydrolyze plant-derived aromatic β-glucosides such as salicin, arbutin and esculin, are able to avoid predation by the bacteriovorous amoeba Dictyostelium discoideum and nematodes of multiple genera belonging to the famil...

The scale of the impact of petroleum products on the natural environment is still difficult to determine. This is why it was decided to conduct tests, under the conditions of a pot experiment, for the effects of diesel oil (0, 4, and 8 mL/kg dry matter of soil) on the yield of oat, content of macroelements, as well as the microbiological, biochemical, physicochemical and chemical properties of ...

soils bacteria are frequently faced with various adverse environmental conditions and have developed a complex regulatory network to respond rapidly to environmental changes. in this study usefulness and applicability of stress proteins of bacteria which are produced after stress conditions were examined. the adaptation of soil bacteria involves the induction of stress proteins provide a nonspe...

Vertical wind shear and concentration gradients of viable, airborne bacteria were used to calculate the upward flux of viable cells above bare soil and canopies of several crops. Concentrations at soil or canopy height varied from 46 colony-forming units per m over young corn and wet soil to 663 colony-forming units per m over dry soil and 6,500 colony-forming units per m over a closed wheat ca...

objective: listeria monocytogenes is a facultative, gram-positive bacterium which is found in soil, water, decaying vegetables, raw milk, and contaminated dairies. listeria monocytogenes causes listeriosis. listeriosis is a zoonosis disease, which transfers from animals to humans by animal feces and contaminated dairies. listeriosis causes the flu like disease or self-limited enteritis, but it ...
