Resumo: | Heavy metals are widely distributed in the environment, and may can find natural, industrial, agricultural and other origins. The accumulation of these metals in water bodies is related to several environmental issues, especially regarding the quality of drinking water. Therefore, the general objective of this study was to isolate, identify and characterize bacteria tolerant to nickel and cobalt metals present in raw water samples and in the sediment of the Rio Traíras - Niquelândia (GO). A total of 68 bacterial isolates were obtained, which were submitted to the microdilution method to determine the minimum inhibitory concentration (MIC). Based on the results found, 12 bacterial choices were chosen, which internationally higher and lower tolerance, being classified according to their microscopic and tinting characteristics. According the results obtained, it is possible to observe the tolerance of isolated bacteria to high concentrations of metals, suggesting its use as a biotechnological tool for the remediation of contaminated areas. |

La acumulación de estos metales en los cuerpos de agua está relacionada con varios problemas ambientales, especialmente en lo que respecta a la calidad del agua potable. Así, el objetivo general de este estudio fue aislar, identificar y caracterizar bacterias tolerantes a los metales níquel y cobalto presentes en muestras de agua cruda y en el sedimento del Río Traíras - Niquelândia (GO). Se obtuvieron 68 aislamientos bacterianos, los cuales fueron sometidos al método de microdilución para determinar la concentración mínima inhibitoria (CMI). Con base en los resultados encontrados, se seleccionaron 12 aislamientos bacterianos, que presentaron mayor y menor tolerancia, y estos se clasificaron según sus características microscópicas y colorantes. De acuerdo con los resultados, se observó la tolerancia de bacterias aisladas a altas concentraciones de metales, lo que sugiere su uso como herramienta biotecnológica para la remediación de áreas contaminadas.Os metais pesados se encontram amplamente distribuídos no meio ambiente, podendo ser advindos de origens naturais, industriais, agrícolas e outras fontes. O acúmulo desses metais em corpos hídricos está relacionado a diversas questões ambientais, sobretudo a respeito da qualidade da água para consumo. Sendo assim, o objetivo geral desse estudo foi isolar, identificar e caracterizar bactérias tolerantes aos metais níquel e cobalto presentes em amostras de água bruta e no sedimento do Rio Traíras - Niquelândia (GO). Foram obtidos 68 isolados bacterianos, sendo estes submetidos ao método de microdiluição para determinar a concentração inibitória mínima (CIM). Com base nos resultados encontrados, foram selecionados 12 isolados bacterianos, que apresentaram maior e menor tolerância, sendo estes classificados de acordo com suas características microscópicas e tintoriais. De acordo com os resultados observou-se a tolerância das bactérias isoladas a altas concentrações dos metais, sugerindo seu uso como ferramenta biotecnológica para a remediação de áreas contaminadas.Research, Society and Development2021-06-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1583110.33448/rsd-v10i6.15831Research, Society and Development; Vol. 10 No. 6; e40510615831Research, Society and Development; Vol. 10 Núm. 6; e40510615831Research, Society and Development; v. 10 n. 6; e405106158312525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/15831/14243Copyright (c) 2021 Venine Prado Saêta; Aline Rodrigues Gama ; Tháis Reis Oliveira; Patricia Thieme Onofri Saiki; Thiago Lopes Rocha; Lilian Carla Carneirohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSaêta, Venine Prado Gama , Aline Rodrigues Oliveira, Tháis Reis Saiki, Patricia Thieme Onofri Rocha, Thiago Lopes Carneiro, Lilian Carla 2021-06-10T22:51:46Zoai:ojs.pkp.sfu.ca:article/15831Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:34.382762Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
