The article shows the effectiveness of the biological product "SHER" developed by "Scientific Industrial Enterprise" AltaiAgroFarm Ltd "(Kazakhstan) on a carrier in the form of screening from local wastes of limestone-shell rock in the process of cleaning soils from oil with a high paraffin content. The results of NGS-sequencing of the consortium of microorganism as part of the probiotic biological product "SHER" established a microbiome of the following type: at the class level 96.15% of all representatives of the consortium were identified as Bacilli, of which 95.69% of bacteria at the order level were identified as Lactobacillales. A method has been developed for immobilizing bacteria of the biological product "SHER" on a carrier in the form of screening out from local waste of shell limestone. Based on the research results, it was established that the immobilization of bacteria of the biological product "SHER" by the carrier in the form of screening of limestone-shell rock showed a high degree of purification of oil-contaminated soil (88.63%). To study the further activity of bacteria, experiments were carried out on the secondary use of the residual stock solution of the biological product "SHER" used in the process of cleaning oil-contaminated soil. The results of experimental studies using residual mother liquor and immobilization by screenings showed the degree of soil purification (45.7%). X-ray spectral analysis determined the elemental composition of the cleaned soil, revealed the presence of a low content of metals: 1.42% Fe and 0.84% Al. It was found that on a carrier in the form of screening out from local wastes of limestone-shell rock, the effectiveness of the biological product "SHER" increases.

“…The implication is that they may have likely contributed to some level of reduction of petroleum hydrocarbons in the oil-based drill cuttings contaminated soils. Besides Erwinia sp, which was isolated from drill cuttings, has been shown to have capability to degrade petroleum hydrocarbons (Pleshakova et al, 2018). Furthermore the bacteria species have been isolated from petroleum hydrocarbons contaminated sites (Ajayi & Abiola, 2018;Anwar et al, 2020;Mahmoud & Bagy, 2019).…”

IntroductionThe Niger Delta is a center for oilfield operations, which involves exploration and production. This however leads to waste generation that when not properly handled impacts the environment negatively. Oil-based drill cuttings are generated in large quantities during drilling for oil and gas. They are presently being managed by re-injection and thermal desorption but these approaches are not environment friendly (Mkpaoro et al., 2015). A possible solution to avoid this problem would have being to stop use of oil-based muds, which leads to production of oil-based drill cuttings that usually contain high concentrations of petroleum hydrocarbons and some amount of heavy metals and salts (Kogbara et al., 2019;Zhu et al., 2019). The advantages of enhanced penetration rate, increased production time, and lowered operation costs (Mkpaoro et al., 2015) associated with oil-based muds however encourages their use in place of a relatively environment friendly water-based and synthetic based muds.Phytoremediation is an eco-friendly and viable technology for reducing petroleum hydrocarbon concentration in oil-based drill cuttings contaminated soils (Dumkhana & Ekemube, 2020;Kogbara et al., 2019;Zhu et al., 2019). This technology involves use of living plants to detoxify, degrade, and immobilize contaminants. The plant roots make direct contact with soil contaminants during phytoremediation and they provide a zone, called rhizosphere, for increased microbial activities. By implication, phytoremediation of soil contaminants, especially biodegradable ones, are more effective when conditions for microbial growth are maintained. Nutrient supply is a main consideration for maintaining optimum growth of plant and soil micro-organisms. This is because nutrient depletion is a limiting factor for plant and microbial growth in petroleum hydrocarbon contaminated soils. But grass species are hardy, grow in low nutrient soils, and have a fibrous root system with large surface area for plant-microbe associations. Microorganisms, including bacterial and fungal species, carry out degradation of petroleum hydrocarbons and have been isolated in polluted sites (Mahmoud & Bagy, 2019). Considerable phytoremediation efficiency has been achieved with grass species planted in oil-based drill
