Opis:: This paper represents the results of the investigation of soil phytotoxicity with a high level of oil pollution. The artificially contaminated soils were exposed to an oil-destroying biosurfactant based on the strains of Bacillus amyloliquefaciens and Bacillus subtilis. The main objective of the work was to evaluate the effectiveness of a consortium of microorganisms in reducing the phytotoxicity of soils with high levels of oil contamination. The determination was performed on the reactions of test organisms to the pollution of the soil environment. The test system in the experiment comprised Sorghum bicolor subsp. Drummondii, Phleum pretense, Galéga officinális, Trifolium pretense, Medicágo sativa, and Sinapis arvensis. The variety of the applied indicator plants has provided a comprehensive analysis of the results of oil destruction and allowed an assessment of the sensitivity of the seeds of each species to toxic substances.

Opis:: This work is devoted to studying the dynamics of changes in phytotoxicity of oil-contaminated meadow soils in the process of microbial bioremediation. The research was conducted under laboratory and field conditions. Winter rye (Secále cereále) was selected as the test object. In order to assess the degree of toxicity in the laboratory, the indicators of seed germination – germination rate and germination energy-were determined. In a field experiment, the ecological state of oil-contaminated soils was evaluated by the germination rate and the amount of aboveground plant biomass. The research results showed that the content of petroleum products significantly affected the percentage of germination of rye seeds. There are differences in the size of seedlings for different experimental schemes: in all tests, the average height of cleoptila on polluted soil was less than on unpolluted soil, but at the same time it varied for different experimental bioremediation schemes. The use of potassium humate and modified vermiculite as additives significantly reduced the toxicity of the oil-contaminated soil.

Opis:: Contamination of soil and water with petroleum during its extraction, collection, transportation, storage and preparation occurs frequently, and purification of oil spills is one of the pressing environmental problems of oil producing organizations. There are a large number of methods for utilization oil spills. The sorption method in combination with bioremediation is capable of effectively purification of petroleum contaminated soils. The paper shows the possibility of using a carbonized mixture of shungite from the Koksu deposit (Kazakhstan) with rice husk as a sorbent and carrier of microorganism strains. The physicochemical properties and elemental composition, as well as the microstructure of carbonized samples were established. The maximum sorption capacity of carbonized sorbents when purifying the soil samples from oil from the Karazhanbas field was 1.86 g/g after 60 days. The carbonized samples with microorganism strains immobilized on them showed a degree of oil destruction reaching 90%.

Opis:: Bacterial co-metabolism in composting process has been widely used to remove hydrocarbons, aided by in-situ production of bio-based surfactants, in terms of compost humic acid-like substances and biosurfactants. The properties of compost humic acid-like substances have been shown in previous studies as potential surface tension reducers and emulsifiers for hydrocarbons. The current study aimed to analyze the properties of biosurfactant of surface tension decrease, emulsification activity, and hydrocarbon solubilization ability. Four indigenous bacteria consortia were isolated from composted materials of yard waste, rumen residue, crude oil-polluted soil, and the mixture of polluted soil with organic waste (1:1, w/w) at day 0th, 20th, 40th, and 60th. Organic waste consists of yard waste and rumen residue in the ratio of 1:1. The isolated indigenous bacteria consortia were incubated for 7 days in different media, i.e., organic waste extract, 6.00% of crude oil, and a mixture of organic waste extract with 6.00% crude oil. The results indicated that the surface tension decrease and emulsification activity of biosurfactants were 8.35–52.90 mN m-1 and 0.00–12.00%, respectively, which showed the potential as surface tension reducers with low emulsification activity. The higher hydrocarbon solubility was shown by the biosurfactant from the rumen residue (13 620 µg g-1) and the mixture (10 998 µg g-1) at day 40th, which was comparable to 1.50% of Tween 80. The biosurfactants in the current research were produced with the same materials, process, and time as compost humic acid-like substances which acts as in-situ bio-based surfactants. The respective ability to solubilize hydrocarbon might be combined and estimated to be higher than Tween 80 of 24 329 µg g-1 and 21 619 µg g-1 for rumen residue and the mixture, respectively. Therefore, it was concluded that the best composition for in-situ bio-based surfactant production to assist the degradation of hydrocarbon through composting process is polluted soil with organic waste (1:1, w/w). The solubility of hydrocarbons can be increased without synthetic surfactants addition, but through providing nutrients to maintain in-situ bio-based surfactant production with intermittent addition of organic waste every 40 days. This method is expected to be an appropriate approach in composting development as a cost-effective sustainable bioremediation technique for polluted soil.

Opis:: At present, the development and optimization of methods to eliminate the consequences of soil contamination with hydrocarbons is gaining increasing economic and social importance; it is the basis for sustainable development of the oil industry. Within the frames of the scientific research, a review of literature was carried out in the sphere of utilization of organic wastes from the food industry in reclamation of oil-contaminated soils; an experimental study of efficiency of the use of wastes from the brewing industry in the process of bioremediation of oil-contaminated soils was conducted and phytotoxicity of these wastes was determined. Experimental research was conducted at different initial concentrations of oil in the soil, which allowed to establish the optimal range of oil pollution level at which the efficiency of brewing waste use is the highest. Thus, at low concentrations (1000–2000 mg/kg), the dynamics of oil concentration decrease in the soil remained preserved throughout the whole duration of the experiment, and the efficiency of oil destruction in the soil exceeded 98%, which confirmed the overall efficiency of application of brewing waste for reclamation of oil-contaminated soils.
