Kinetics of the Growth of White-Rot Fungus Coriolus hirsutus in Soil for Bioremediation

Abstract

The growth of the basidiomycete Coriolus hirsutus on soil has been studied in a series of experiments. When the soil was polluted with bisphenol A, elimination of the chemical from the soil was completed for 99% by the 30th day by using an aqueous solution of MYG medium for water content control and setting a well mixed condition of soil. For achieving higher growth rate and larger colony of the fungus on soil, it was found to be necessary that the water content control liquid includes a sufficient amount of nutrients. Microscopic observation on hyphae growth on agar showed that glucose concentration positively influenced on the rate of hyphal tip extension and the colony diameter. Evidence was presented that the removal of bisphenol A from contaminated soil was elevated by increasing the growth of C. hirsutus on soil.
