“…Доминирование актинобактерий в почве связано с присутствием полимеров природного и антропогенного происхождения: нефтепродуктов [11], кератина [8], хитина [12] и др. В микрокосмах, загрязнённых углеводородами, по сравнению с ненарушенными системами, отмечалось увеличение доли филума Actinobacteria, особенно рода Galiella (в образцах, загрязнённых бензином) и рода Nocardioides (в образцах, загрязнённых дизельным топливом) [12]. Внесение азотсодержащего полисахарида хитина в микрокосмы на фоне поллютантов на порядок увеличивало численность популяций метаболически активного микробного сообщества, способствовало оструктуриванию почвы и формированию агрономически ценной структуры, а также приводило к снижению количества остаточных нефтепродуктов.…”

Actinobacteria are gram-positive aerobic and facultative anaerobic bacteria that tend to form branching hyphae capable of developing into mycelium. Their main role is in the decomposition of complex polymers in the soil: lignin, cellulose, chitin, humus substances; fertility formation; production of antibiotic substances; accumulation of biologically active compounds. Actinobacteria secrete into the environment a complex of secondary exometabolites of various compositions with aliphatic, carbocyclic, heterocyclic, nitrogenous, oxygen-containing and sulfur-containing compounds. Most of the isolated secondary metabolites have antibiotic, antimicrobial, antiviral, herbicidal, insecticidal properties. Biotechnological capabilities of soil actinobacteria producing biologically active substances with a wide range of environmental effects are used in the development of multifunctional biologics for various industries. Actinobacteria play a crucial role in optimizing the growing conditions of plants, and therefore there is a natural interest in studying the factors that influence the relationship between actinobacteria and various crops in specific soil conditions. The development of this issue is an important link in the ecological characterization of the soil microbial complex and it will help to develop the theoretical foundations for the targeted regulation of the interactions of actinobacteria with phytopathogenic microorganisms and insect pests. The purpose of this work is to analyze the ecological features and biotechnological capabilities of soil actinobacteria. The review describes the distribution of actinobacteria in various types of soils, including those with the presence of pollutant; the composition of the metabolites produced; relationships with other microorganisms, as well as biotechnological properties and the possibility of using actinobacteria for the development of biological products for agroecosystems.

“…Quantitative analysis of petroleum hydrocarbon in porous media mainly includes gravimetric (Adeniji et al. ), infrared (Manucharova et al ), ultraviolet reflection (Mathew ), fluorescence (Yang et al ), and turbidity (Fujita et al ) methods and gas chromatographic techniques (Adebiyi et al ). Nowadays, Extraction‐ultraviolet spectroscopy is a widely used method for the analysis of petroleum in porous media (Zheng et al ) and it was chosen as a representative method for this study.…”

The oil content of oil‐contaminated porous media is an important parameter for the assessment and remediation of oil pollution in soil and groundwater. However, an accurate measurement method is not available. In this study, we propose a new equation to calculate the oil content of water‐bearing media based on traditional extraction–ultraviolet spectroscopy. Further, an improved experimental method was developed. The results indicate that the pure solid weight and oil content of oil‐contaminated media can be accurately determined by introducing the oil drying loss coefficient (γ). The average relative errors of the improved method range from −0.14% to −0.96%. They are much smaller than errors of −4.49% to −10.97% of the original methods, indicating that the accuracy of measured oil content is enhanced. In addition, the accuracy of the new method does not depend on oil volatility and oil content.
