It has been found that the presence of biological contaminants in tanks, such as corrosion products, microorganisms of various origins, resinous deposits of fuels and lubricants (F&L), can lead to their destruction and a decrease in the condition of F&L, which negatively affects the safety of aircraft flights and the operation of special vehicles. Yeast-like fungi and bacteria were isolated and identified from samples of aircraft TS-1 and diesel fuel: the substrate-specific gassing fungus Hormoconis resinae (Cladosporium resinae) and bacterial cultures of both Grampositive (G+), Gram-negative (G-) and G-variable "associations". It was found that these microorganisms are able to grow in the presence of F&L, forming powerful colonies of motile and non-motile rod-shaped bacteria. Based on the analysis of the data obtained, it is assumed that in the detected biological contamination of F&L, microorganisms can coexist only in the composition of biofilms. This assumption needs to be further investigated, as does the claim that the adhesion ability of F&L is an important step in the process of their utilization by microorganisms.
