An effective approach for the degradation of phenolic waste

The rapid growth and development of industrial sectors releases massive amounts of phenolic contaminants into the aquatic environment. Bioremediation is a long‐term and cost‐effective way of removing phenolic contaminants from the environment. The success of bioremediation depends heavily on the biomass growth, enzymatic activities of microbial communities, their interactions, and other cellular metabolic activities related to phenolic degradation. Thus, the current review paper focuses on evaluating the microbial remediation of phenolic contaminants as well as the many challenges that come with it, with special reference to: (i) uses, occurrence of phenolic pollutants, and contamination levels; (ii) factors affecting phenolic biodegradation and biomass growth, such as the effect of temperature, pH, agitation speed, carbon sources, inoculum size, and age. The nutritional requirements for improved microbial growth and biodegradation of phenolic from contaminated environments were also highlighted, with a particular emphasis on the role of culture medium components and various redox mediators in phenolic compound removal. The efficiency of phenolic biodegradation has also been compared with a number of previously described advanced oxidation processes.

Com o desenvolvimento urbano e social das cidades, os moradores que residem nas proximidades de riachos e vales passam a sofrer as consequências do lançamento contínuo de esgoto. O objetivo deste trabalho foi avaliar a qualidade da água do Ribeirão Floriano, localizado no município de Maringá-PR. Para tanto, quatro pontos, denotados por P1, P2, P3 e P4, foram escolhidos. Para a análise de DQO todas as coletas realizadas apresentaram a mesma concentração, sendo inferior a 15 mg L-1, porém, em relação ao DBO5 no período do verão os pontos P2, P3 e P4 mostraram-se dentro do limite esperado, 2.0 mg L-1, para águas superficiais de Classe II, de acordo com a legislação. Em relação a análise da contagem de Escherichia coli os maiores valores encontrados, para a contaminação biológica do ribeirão, foram nos pontos P2 e P3, equivalentes a 2000 UFC/mL e 424 UFC/mL, respectivamente, no período da primavera. Estes dois pontos estão localizados próximos a lavanderias industriais que podem estar associados a lançamento de efluentes advindos destas empresas. Nas análises, foi determinado concentrações elevadas de cobre (Cu), alumínio (Al) e níquel (Ni), evidenciando uma distribuição equitativa da ação antrópica em todo o curso do ribeirão. Estes resultados sugerem a necessidade da implantação de programas de monitoramento ambiental em águas superficiais nos rios do município.

Bioremediation is a technique to enhance natural biological processes to rectify polluted groundwater, soil, and even entire habitats. Bioremediation techniques use biological agents to act upon hazardous, toxic materials and subsequently convert them into less toxic substances. Microbes are organisms ubiquitously present in the biosphere. These microorganisms are the main agents that remediate toxic and polluted environmental conditions. Highly polluted areas can be rectified using proper bioremediation procedures and interventions. In this review we have studied the different bioremediation techniques which can be utilized to correct the harmful effects of environmental pollution. In this study we have also emphasized on the benefits of adopting bioremediation as an efficient alternative technique in comparison to the traditional physical and chemical methods to restore the healthy environmental conditions.
