“…Властивість мікроорганізмів засвоювати вуглеводні твердих, рідких та газоподібних нафтопродуктів була відома ще на початку XX ст. Це явище стало причиною виникнення суттєвих проблем у сфері нафтодобування, нафтоперероблення і нафтохімії, а особливо під час експлуатації нафтопродуктів [1][2][3][4][5][6].…”

“…The presence of water containing mineral salts is crucial for the development of biodamage [ 14 , 15 ]. In a dry fuel, microbial growth is not observed, but even a trace of water (0.01–0.02%) is sufficient for harmful microorganisms to grow [ 16 ].…”

“…Fuel biodamage is caused by bacteria, filamentous fungi, and yeast [ 6 , 8 , 10 , 12 , 19 ]. Filamentous micromycetes are the most dangerous among them because they form aggressive waste products and their mycelium can clog fuel systems [ 8 , 14 ]. The following fungal genera are common in biofuel: Aspergillus, Penicillium, Fusarium, Amorphotheca, Neosartorya, Paecilomyces, Talaromyces, Graphium, Cladosporium, Candida, Yarrowia, Schizosaccharomyces, Saccharomyces , and Pichia [ 3 , 7 , 8 , 11 , 13 , 19 , 20 , 21 ].…”

Fuel (especially kerosene) biodamage is a challenge for global industry. In aviation, where kerosene is a widely used type of fuel, its biodeterioration leads to significant damage. Six isolates of micromycetes from the TS-1 aviation kerosene samples were obtained. Their ability to grow on the fuel was studied, and the difference between biodegradation ability was shown. Micromycetes belonged to the Talaromyces, Penicillium, and Aspergillus genera. It was impossible to obtain bacterial isolates associated with their mycelium. However, 16S rRNA metabarcoding and microscopic observations revealed the presence of bacteria in the micromycete isolates. It seems to be that kerosene-degrading fungi were associated with uncultured bacteria. Proteobacteria, Actinobacteria, Bacteroidetes, and Firmicutes were abundant in the fungal cultures isolated from the TS-1 jet fuel samples. Most genera among these phyla are known as hydrocarbon degraders. Only bacteria-containing micromycete isolates were able to grow on the kerosene. Most likely, kerosene degradation mechanisms are based on synergism of bacteria and fungi.

“…More than 10 thousand hectares of the country's territories today are already buried under millions of tons of waste, which, at sites of unauthorized storage, pose a huge environmental danger. The absence of a separate collection system in spontaneous landfills, where the hazardous waste of various morphological diversity and chemical composition accumulates uncontrollably, in the process of decay leads to the concentration of hazardous toxicants and pollutants in the body of the landfill [5,6].…”

This paper reports an analysis of current issues related to storing solid household waste, and, specifically, the problem of environmental pollution when unsorted solid household waste (SHW) is ignited. A technology has been developed to improve environmental safety and ensure a reduction in the anthropogenic load on the atmosphere, hydrosphere, and lithosphere in the event of fires at the sites of solid waste storage. The operation of the proposed equipment, taking into consideration all the provided operating modes and additional options, is energy-saving and automated (or semi-automatic), which makes it especially relevant under modern conditions. The technology significantly improves the efficiency of the processes to eliminate the ignition of SHW and localize their environmental consequences for the territories adjacent to landfills. Laboratory tests were carried out, which proved the effectiveness of practical application for the designed equipment of a new environmentally active adsorption mixture for the purpose of cleaning the waste filtrate, as well as its use for the formation of an anti-filtration screen in the mound of SHW. Experiments have shown that the tested sample of the aqueous suspension of the proposed environmentally active mixture adsorbs calcium (by 92 %), overall iron (by 91 %), overall phosphorus (by 75 %), zinc (by 31 %), and ammonium (by 19 %). This leads to a decrease in the overall toxicity of the solution and indicates the possibility of improving the environmental safety of waste fires when operating the proposed technical solution by purifying the filtrate released during fires in landfills. The reported results, specifically, the technology for localizing the environmental consequences of uncontrolled waste ignition could be used in the process of modernizing the technical support for sanitary treatment schemes in urban areas.
