Resumo: Evaluation of the physical-chemical and biological treatment of residue from dyes produced at a microbiology laboratory. The different types of waste produced by man in several areas represent a serious environmental problem when incorrectly discharged. This work carried out degradation experiments of dye waste generated at the laboratory of microbiology of the Federal University of Technology – Paraná State, Campus Curitiba. Assays were performed through liquid culture implemented with Pleurotus sajor-caju and advanced oxidative process (AOP - System UV/H2O2). Efficiency verification of these processes was carried out through monitoring color removal and aromatic compounds by spectrophotometric analysis (UV-vis), and also by controlling the reduction of organic matter (Chemical Oxigen Demand analysis), as well as by performing toxicity bioassays with Escherichia coli and seeds of Lactuca sativa. Results indicated that the combined process – liquid culture followed by peroxidation with ultraviolet radiation, proved to be the most effective treatment for color removal (90-95%) and degradation of aromatic compounds (16-20%). Bioassays showed that the raw dye waste samples did not inhibit E. coli growth, but showed potential toxicity to the species of L. sativa, inhibiting seeds germination by 30 to 57%.

No presente trabalho, foram realizados experimentos de degradação de resíduos de corantes gerados no Laboratório de Microbiologia da Universidade Tecnológica Federal do Paraná, Campus Curitiba, por meio do cultivo líquido implementado com Pleurotus sajor-caju e processo oxidativo avançado (POA – Sistema UV/H2O2). A verificação da eficiência desses processos foi realizada por meio do acompanhamento da redução de cor e dos compostos aromáticos por análise espectrofotométrica em UV-vis, da redução de matéria orgânica (análise de DQO) e de bioensaios de toxicidade com Escherichia coli e com sementes de Lactuca sativa. A partir dos resultados obtidos, constatou-se que o processo combinado – cultivo líquido seguido de peroxidação com irradiação ultravioleta, demonstrou ser o tratamento mais eficiente para a redução de cor (90-95%) e degradação de aromáticos (16-20%). Os bioensaios revelaram que as amostras do resíduo bruto não inibiram o crescimento da E. coli e mostraram potencial tóxico para a espécie L. sativa, apresentando de 30 a 57% de inibição da germinação das sementes testadas.Universidade Estadual De Maringá2009-11-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/754510.4025/actascitechnol.v32i1.7545Acta Scientiarum.
