The biostimulation potentials of carrot peel waste and carob kibbles for bioremediation of crude petroleum-oil polluted soil were investigated. Temperature, pH, moisture, total petroleum hydrocarbon (TPH), and changes in microbial counts during 45 days were monitored when 4 mL of carrot peel waste or carob kibbles media were added to 200 g of crude oil polluted soil samples. Gas chromatography-flame ionization detection (GC-FID) was used to compare hydrocarbon present in the crude oil polluted soil and in pure fuel, composition of crude oil polluted soil was analyzed by X-ray diffraction (XRD), and the TPH was measured by distillation using distiller mud. The results showed that, at the end of experiments, the concentration of TPH decreased in crude oil polluted soil containing carrot peel waste with a percentage of 27 ± 1.90% followed by crude oil polluted soil containing carob kibbles (34 ± 1.80%) and in the unamended control soil (36 ± 1.27%), respectively. The log [Colony Forming Unit (CFU)/g] of total heterotrophic bacteria in the crude oil polluted soil increased from 10.46 ± 0.91 to 13.26 ± 0.84 for carrot peel waste, from 11.01 ± 0.56 to 11.99 ± 0.77 for carob kibbles and from 8.18 ± 0.39 to 8.84 ± 0.84 for control, respectively. Such results demonstrated that carrot peel could be used to enhance activities of the microbial hydrocarbon-degrading bacteria during bioremediation of crude petroleum-oil polluted soil.

“…Moreover, the reduction in the total petroleum hydrocarbons (THC) of the soil by indigenous microorganisms was dose dependent: the higher was the treatment levels the lower was the THC content in the soils. Alotaibi et al [23] also showed that wheat straw when applied to crude oil-contaminated soil enhanced the biodegradability of pollutant, especially at contamination levels of up to 100-150 mL crude oil/kg. Consequently, we can conclude that supplementation of soil with lignocellulosic material at a certain rate extends the bioremediation process carried out by the fungi.…”

In the present study, the ability of eighteen white-rot basidiomycetes was evaluated for crude oil biodegradation. Cerrena unicolor strains, Panus tigrinus 433, P. lecometei 903, Pleurotus ostreatus 70, Trametes maxima 403, and T. versicolor 159 showed especially abundant mycelial growth on the surface of agar covered with droplets of crude oil. In the submerged cultivation in the glucose (3 g/L) containing medium, complete decolorization of indicator Resazurin was observed during two weeks in the presence of Bjerkandera adusta 139, C. unicolor 303, Coriolopsis gallica 142, P. ostreatus 70, P. pulmonarius 148, and T. versicolor 159. When artificially oil-polluted soil was inoculated with fungal mycelium pre-grown on a mixture of wheat straw and mandarin peels the maximum degradation rate (65%) was obtained when C. unicolor 305 was incubated in the 1% oil-containing soil for 28 days. At the same cultivation conditions, P. ostreatus 2175 eliminated 43.9% of initial oil when its concentration in the soil was increased to 2%. In the lignocellulose-containing soil, neither glucose nor yeast extract enhanced oil degradation, but wetting of soil with the distilled water to maintain its humidity favored oil elimination. The tested WRB secreted lignin-modifying enzymes in the presence of petroleum hydrocarbons; the higher was the concentration of lignocellulosic substrate in the soil the higher was the fungi enzyme activity. However, the data received did not show any direct relationship between the fungi enzyme activity and the degree of oil elimination. Key words: mycoremediation, crude oil, basidiomycetes, cultivation conditions, lignin-modifying enzymes

“…Уровень токсического воздействия зависит от преобладающих фракций нефтепродукта и убывает в ряду ароматические углеводороды > циклопарафины > олефины > парафины (Новоселова и др., 2014). Присутствие углеводородов нефти в почве приводит к увеличению количества азотфиксаторов, аммонификаторов, денитрификаторов и снижению актиномицетов и целлюлозоразлагающих бактерий (Кириенко, Имранова, 2015;Михайлова и др., 2016;Alotaibi et al, 2018). Особую группу составляют углеводородокисляющие бактерии (УОБ), в отношении которых нефтепродукты оказывают стимулирующее действие, приводя к возрастанию их численности и длительному сохранению на загрязненных территориях (Гоголева, Немцева, 2012;Mikolasch et al, 2019).…”

In the course of the conducted studies, main groups of soil microorganisms in the southern chernozem were identified. The resistance of isolates to the action of oil in the concentration range of 15–25%, the possibility of using it as a carbon source, the ability of soil microbiota to biodegradate oil in contaminated soil and the resistance of bacteria to low temperatures, high NaCl concentrations, acid and alkali resistance were established. 15 genera (31 species) of heterotrophic bacteria were isolated from uncontaminated soil samples of the southern chernozem subtype. Our assessment of the abundance dynamics of microorganisms isolated from laboratory contaminated soils showed that as a result of oil exposure, there was a significant decrease in the numbers of microorganisms: by the 180th day of our experiment, 10 bacteria species belonging to 3 genera were isolated, namely: Bacillus, Micrococcus and Serratia. Among the isolated bacteria, resistance to the action of the pollutant at a concentration of 25% was established for B. coagulans, B. mojavensis, B. megaterium, M. luteus, as well as for the museum strain of B. pumilus CM. By cultivating the studied bacterial strains on a carbon-free medium M9 with 15 and 20% oil added, their ability to use petroleum hydrocarbons as the only carbon source was established; however, when the concentration increased to 25%, only M. luteus, B. mojavensis and B. pumilus KM retained this ability. The presence of hydrocarbon-oxidizing bacteria in soil samples contributed to the 42% decrease in the oil mass concentration in 180 days. The most significant decrease in the concentration of petroleum products occurred in the period from the 10th to the 30th day and amounted to 25%, which is probably due to the increase in the numbers of heterotrophic bacteria. The ability to grow at a temperature of +4°C was established for representatives of the genus Bacillus, including the museum strain of B. pumillus CM, 4 strains of bacilli remained viable in an acidic environment (pH 5), 7 strains of bacilli and M. luteus and S. plymuthica remained viable in an alkaline environment (pH 9). The studied bacterial strains were growing on a GRM-agar with a NaCl concentration of 7%, the ability to grow at a NaCl concentration of 15% was preserved only by the museum strain of B. pumillus KM. The obtained results open the prospects for the use of hydrocarbon-oxidizing bacteria with a high adaptive potential as potential oil destructors capable of biodegradation at low temperatures, in conditions of high salinity and in a wide range of pH of the medium.
