Realizou-se estudos avaliando a ação da biomassa viva e inativada de Cunninghamella elegans crescida, visando à remoção do hidrocarboneto aromático policíclico fenantreno. Monitorou-se o processo de remoção do fenantreno a cada 24 h por espectrofotometria, de acordo com um planejamento fatorial completo de 22 e, como variáveis independentes 0,1 e 0,2 mM de fenantreno, na presença de 0,6, 3,3 e 6% de glicose e variável resposta o conteúdo de fenantreno removido. Os resultados obtidos indicaram que tanto a biomassa inativada como viva removeram, respectivamente, 90,0% e 82,0% a concentração de 0,2mM de fenantreno na presença da menor concentração de glicose (0,6%). A biomassa inativada de C. elegans demonstrou ser um sorbente com elevado potencial biotecnológico para a remediação de áreas poluídas com hidrocarbonetos aromáticos policíclicos. Abstract Studies were carried out evaluating the action of the life and inactivated biomass of Cunninghamella elegans grown to removal polycyclic aromatic hydrocarbon phenanthrene. The removal process was monitored each 24h by spectrophotometry, de acordo com according to full factorial design 2 2 , and independent variables the phenanthrene concentrations [0.1 and 0.2 mM], and the content of phenanthrene removed as variable response.The results showed that both inactivated and live biomass from C. elegans removed 85.0% and 90.0%, respectively, of phenantrene of 0.2 mM on glucose (0.6) concentration. The inactivated biomass from C. elegans shows a sorbent with high biotechnological potential for bioremediation of polluted area with polycyclic aromatic hydrocarbons.
