Resistance and Application of the Biomass from Fusarium solani in the Removal of Pentachlorophenol in Aqueous Solution

Abstract

Recently, the removal and degradation capacity of different environmental contaminants such as heavy metals, organic solvents, oils, plastics, pesticides and herbicides, from sites contaminated by low-cost materials has been studied, with promising results. These adsorbents include agricultural and industrial waste, clay minerals, live and dead microorganismos, and others materials. The objective of this investigation was study the tolerance and removal capacity of pentachlorophenol by the environmental polluting fungus Fusarium solani, by UV-visible spectrophotometry method. The fungal strain grew on LMM supplemented with 80 mg/L of PCP about 6% of growth relative to control (118 mg of dry weight without of pesticide) was obtained. The highest adsorption was obtained at pH 5.0, at 28oC after 24 hours of incubation with 1 g of fungal biomass, and 100 rpm. If we increase the PCP concentration, the removal capacity decrease, and if the biomass concentration is increase, the removal is most efficient, and the laccase activity is increase in presence of 10 mg/L of PCP, with a degradation of 63% at 15 days of incubation.
