Degradation of Oil and Petroleum Products in Water by Bioorganic Compositions Based on Humic Acids

The use of nature-like technologies, leading to acceleration the processes natural destruction pollutants, is one promising directions for oil and petroleum product degradation in environment. joint oil-degrading bacteria polymers with properties surfactants humic acids (HAs) bioorganic compositions effective. In this study, from reed peat, which have a critical micelle concentration (CMC) 0.6 g/L, were used as an organic component. Oil-degrading genera Rhodococcus Pseudomonas, increased biodegrading ability relation crude waste engine oil, bacterial Mono- polybacterial based on these components are proposed. emulsification index maximum (94% ± 2%) using composition association strains three bacteria. Analysis films model products vitro showed high degree their after 7 days monobacterial (up 80%) 2 3 (almost 90%). A stabilize emulsions develop has been established, indicates significant potential cleaning environment pollution. combination (all strains) makes it possible achieve stabilizing effect emulsions: transmission coefficients 37–75% lower relative control (oil-polluted water) 50% acids.
