“…In our previous works, thirteen bacterial strains were isolated from the contaminated TS-1 aviation kerosene by conventional microbiological methods on the Rich medium. Their taxonomic affiliation was verified by 16S rRNA sequencing [ 45 , 46 ]. Kerosene was characterized by a diverse bacterial composition that included the following genera: Sphingobacterium, Alcaligenes, Rhodococcus, and Deinococcus .…”

“…Kerosene was characterized by a diverse bacterial composition that included the following genera: Sphingobacterium, Alcaligenes, Rhodococcus, and Deinococcus . Isolated strains were capable of the degradation of hydrocarbons and production of biosurfactants [ 45 , 46 ]. At the same time, in this study, the same bacterial genera were indicated in monospore fungal cultures based on 16S rRNA metabarcoding.…”

“…Hydrocarbon-degrading bacteria live in a hydrophilic environment. At the same time, their immobilization in the vicinity of a substrate is essential for degradation [ 28 , 46 , 83 ]. Thus, biofilm formation is important for microorganisms anchoring on a hydrophobic surface [ 83 ].…”

“…In order to indicate the presence of cultured bacteria associated with the mycelium of the monospore fungal cultures, the following media were used: Rich medium [ 42 ] and Evans medium (EM) [ 43 ]. Previously, it was shown that EM and Rich medium are optimal for isolation of cultured heterotrophic bacteria from samples of contaminated oil and fuel [ 44 , 45 , 46 ]. All isolates of micromycetes were transferred either on liquid or solid media containing 2.0% (wt/ v ) agar.…”

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.
