Аннотация:The species Amorphotheca resinae is best known among micromycetes that deteriorate aviation fuel.It lives in natural conditions in various biogeocenoses and is known as a component of soil mycobiota. Micromycetes of this type have the ability to obtain the necessary carbon for life from hydrocarbon fuel. This happens through the breakdown of complex hydrocarbons to simpler compounds. The growth of A. resinae in fuelleads to numerous problems associated with the operation of aviation equipment: destruction of nonmetallicmaterials, increased corrosion of metal elements, and clogging of fuel filters with mycelial biomass. According to some literature sources, not all strains of this species living in natural conditions can absorb petroleumhydrocarbons. According to other data, there is a tendency that the ability to absorb hydrocarbons is becoming characteristic of an increasing number of soil strains of A. resinae. The authors have studied the growthcapacity of seven strains of A. resinae isolated from various aviation fuel samples and seven strains isolatedfrom different geographical locations and substrates: soil, air, wood, and rooms. Among the studied strains ofA. resinae were both those able to develop due to aviation fuel hydrocarbons and those without this ability. Atthe same time, visual and quantitative methods for evaluating the growth rate and intensity of the studiedfungi strains do not exclude each other and give comparable results. A. resinae strains isolated from fuel samples demonstrated much more active development compared to strains isolated from natural habitats. Fivestrains of A. resinae isolated from different geographical locations of fuel samples showed almost the samedegree of development in the amount of biomass formed during one month.
