Влияние белого фосфора на выживаемость, протеом и клеточную морфологию Aspergillus niger

: Microorganisms are known for their ability to adapt easily to any environment, forming specific ecosystems capable of surviving in harsh media. White phosphorus is one of the most dangerous and toxic pollutants, whose widespread use for various industrial and military purposes creates conditions for environmental pollution. It has previously been shown that some microbial cultures can adapt to the presence of white phosphorus in the environment, oxidizing it to a phosphate and then using it as a source of biogenic macronutrients. In prior studies, we have demonstrated the possibility of white phosphorus biodegradation by the fungal strains of Aspergillus niger. However, it is important to study the resistance of this species to such a toxic substance as white phosphorus. There may be several probable mechanisms, including the following: phosphorus and its transformation products. Microscopic and proteomic studies have confirmed the presence of the above-mentioned resistance mechanisms.
