- Growth Ability of “Kerosene Fungus” Amorphotheca resinae Strains Isolated from Different Habitats in Aviation Fuel
- 作者： Krivushina A. A. Bobyreva T. V. Mokeeva V. L. 来源： Biology Bulletin Reviews 年份： 2023 文献类型 ： 期刊 关键词： biodestructor Aviation Fuel micromycetes of biodeterioration
- 描述： 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 fuel leads to numerous problems associated with the operation of aviation equipment: destruction of nonmetallic materials, 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 petroleum hydrocarbons. 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 growth capacity of seven strains of A. resinae isolated from various aviation fuel samples and seven strains isolated from different geographical locations and substrates: soil, air, wood, and rooms. Among the studied strains of A. resinae were both those able to develop due to aviation fuel hydrocarbons and those without this ability. At the same time, visual and quantitative methods for evaluating the growth rate and intensity of the studied fungi 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. Five strains of A. resinae isolated from different geographical locations of fuel samples showed almost the same degree of development in the amount of biomass formed during one month.
