<p align="justify">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.</p><p align="justify">Abstract</p><p align="justify">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.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
