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...

Wastes from livestock farms contain significant amounts of antibacterial drugs and antibiotic?resistant genes. Due to weak adsorption in the animal's body, antibiotics are released into the environment in an unchanged form or as metabolites in the composition of manure. In addition to the antibacterial agents, the manure of treated animals contains antibiotic?resistant bacteria. The use of manure in untreated form as a soil fertilizer can lead to the spread of antibiotic resistance among soil microorganisms. Compo...
