Many oilfields such as supergiant Romaschkinskoye oilfield in Russia contain heavy oils that are complicated to recover. In order to increase the proportion of obtained oil, methods of enhanced oil recovery are implemented, and microbial methods (MEOR) are considered as safe and efficient once. In-situ MEOR are based on stimulation of oilwell microflora that partly decomposes hydrocarbon molecules or alters oil-water interface tension. Despite oilwells are an environments with anaerobic conditions, many allochtono...

Pollution of aquatic ecosystems with antibiotic-resistant genes originating from human medicine and veterinary is an urgent problem due to the potential threaten to public health. Antibiotic-resistant genes enter surface waters and wastewater through vertical and horizontal water runoff. At the same time, heavy metals and biogenic substances often presented in aqueous ecosystems often exacerbate the problem since the drive the horizontal transfer of antibiotic-resistance genes. To solve the problem of purification...

The problem of carbon dioxide emission from the soil is relevant, since it affects the reduction of the soil organic carbon pool, thereby reducing its fertility and productivity. In addition, carbon dioxide emissions from the soil are a significant contributor to the greenhouse effect. The aim of this work was to evaluate the mineralizing activity of the microbial community of the soil of a new point of observation of carbon dioxide emissions, located in the previously little-studied territory of Russia, using suc...

The present work is an attempt to create a biosurfactant producing consortia on the bases of initial rhizospheric community of lettuce plant (Lactuca sativa). To obtain consortia, 47 strains from the rhizosphere were isolated and checked upon their ability to produce biosurfactants. The ability of the isolates to produce biosurfactants was analyzed on the basis of their ability to emulsify crude oil (E24 index). The isolates with the highest E24 were Bacillus. oryzaecorticis (80%), B. simplex (65%), Paenibacillus ...
