Estudos preliminares sobre atividade adsortiva do corante vermelho congo pelo fungo Lentinus crinitus.

Abstract

The water contamination by industrial dyes is an inquestionable problem, so the use of technologies such as bioremediation may be efficient in wastewater treatment. The use of basidiomycete fungi for bioremediation strategy for the degradation of several xenobiotics, including dyes. In this study the cultivation methods for Lentinus Crinitus in adsorption of the dye red congo were evaluated. The experiments were conducted in stationary crops and agitation of 120 rpm on a bed containing potato broth (2%), and red congo dye at a concentration of 12.5 mg / L. The cultivation was stopped at 24h, 48h and 72h.The parameters variation such as pH, biomass and dye concentration in the culture were evaluated. Visual assessment of all crops allowed to observe the occurrence of adsorption of the dye by the fungus. The tests carried out showed that adsorption of the dye was higher in stationary culture, and no relationship was found between the increase in biomass and the adsorption of the dye Congo Red.
