Utilização do fungo Lasiodiplodia theobromae MMPI na remoção de Cromo VI de efluente de galvanoplastia

Abstract

The effluent brought by electroplating processes contains high concentrations of potentially toxic elements ( heavy metals ) , that require effective treatment before disposal. Considering that many metal removal solutions‟ techniques prove to be expensive and insufficient, and in some cases it‟s also necessary adjuncts processes to aid in the removal , the fungal biomass has been shown to be an efficient biosorbent material, this is due to their technical and economic feasibility. This paper proposes to study the application of a fungus ( Lasiodiplodia theobromae ) for the removal of chromium VI from electroplating effluent . Through fermentation bioreactor bench was obtained biomass grown in medium formulated with mineral salts and a carbon source. Subsequent to its use and application in kinetic experiments in isotherms, it was necessary to kill the cells in autoclave at a temperature of approximately 120 ° C.
