Effect of petroleum contaminant on pin creating and amino acid content of Pleurotus florida (P.Kumm)

Pleurotus florida is an edible mushroom with a high potential for removing oil pollutants. In this study, the effect of gas oil on pin creating and amino acids content was investigated. The gas oil concentrations were used 2.5- 10% and for 30 days.The results showed that gas oil has a positive effect on the pinning stage, and increasing its concentration increases the number of pins. Increasing the concentration of gas oil in the treatments reduced the water consumption pattern. The highest consumption of the aqueous phase belonged to the control sample. Seventeen amino acids were evaluated. The study of amino acids showed that the growth of fungi in gas oil-contaminated environments causes a significant increase in the content of amino acids (15 amino acids). The amino acid hydroxyproline was not reported in the selected gas oil treatment sample. According to these findings, P. florida can be considered as a safe species, with fast growth and resistance to petroleum pollutants for simultaneous removal of contaminants and the use of biomass to produce the required amino acids in the industry.
