Nickel Biosorption by Acinetobacter Baumannii and Pseudomonas Aeruginosa Isolated from Industrial Wastewater

Nickel biosorption ability was evaluated in two bacterial strains: Acinetobacter baumannii UCR-2971 and Pseudomonas aeruginosa UCR-2957, resulting in greatest adsorption at pH 4.5 and a residence time of 100 minutes. Biosorption isotherms showed that the process follows the Langmuir model. The maxim...

description Nickel biosorption ability was evaluated in two bacterial strains: Acinetobacter baumannii UCR-2971 and Pseudomonas aeruginosa UCR-2957, resulting in greatest adsorption at pH 4.5 and a residence time of 100 minutes. Biosorption isotherms showed that the process follows the Langmuir model. The maximum adsorption rates (Nmax) were 8.8 and 5.7 mg·g-1 for A. baumannii and P. aeruginosa, respectively; however, affinity constants suggest that P. aeruginosa (K=1.28) has higher affinity for nickel than A. baumannii (K=0.68). It is suggested that both strains could be used for wastewater treatment, as long as the concentration of Ni2+ is within the range of mg·L-1.

Isotermas de adsorção foram calculadas com as duas linhagens. Observou-se que, para ambas, o processo de adsorção está de acordo com o modelo fisicoquímico de Langmuir. A captação máxima do Ni2+ (Nmax) foi 5.7 e 8.8 mg Ni2+ g -1 para P. aeruginosa e A. baumannii, respectivamente. Não obstante, P. aeruginosa apresenta uma constante de afinidade (K=1.28) maior que A. baumannii (K=0.68). Estes resultados indicam que ambas as linhagens são adequadas para o tratamento de águas contaminadas, desde que a concentração de níquel seja da ordem de mg·L-1.UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias de la Salud::Centro de Investigación en Enfermedades Tropicales (CIET)UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias Básicas::Centro en Investigación en Contaminación Ambiental (CICA)UCR::Vicerrectoría de Docencia::Salud::Facultad de Microbiologíaengacceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccessBrazilian Journal of Microbiology, Vol.37(4), pp. 465-467reponame:Kérwáinstname:Universidad de Costa Ricainstacron:UCRBiosorptionNICKELAcinetobacter baumanniiPseudomonas aeruginosaWASTEWATER TREATMENTNickel Biosorption by Acinetobacter Baumannii and Pseudomonas Aeruginosa Isolated from Industrial WastewaterBioadsorção de niquel por Acinetobacter baumannii e Pseudomonas aeruginosa isoladas de águas residuais industriaisartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleORIGINALNickelAbsorption_Rodriguez-Quesada-Rodriguez.pdfNickelAbsorption_Rodriguez-Quesada-Rodriguez.pdfapplication/pdf155413https://www.kerwa.ucr.ac.cr/bitstreams/c9a45747-22ab-4ad4-897d-77d673726791/download0c4fefdec85da03adb09e60082309353MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-83584https://www.kerwa.ucr.ac.cr/bitstreams/d0879fa7-04c2-45a3-9c3a-4db80b70d3ed/downloadb39c1930822b6ee5a194051b92f3a43eMD52TEXTNickelAbsorption_Rodriguez-Quesada-Rodriguez.pdf.txtNickelAbsorption_Rodriguez-Quesada-Rodriguez.pdf.txtExtracted texttext/plain28322https://www.kerwa.ucr.ac.cr/bitstreams/59f6bacd-e923-400c-8d53-fd6473f1bde5/downloadf6f50bc10cc471d52484f8746104eb58MD53THUMBNAILNickelAbsorption_Rodriguez-Quesada-Rodriguez.pdf.jpgNickelAbsorption_Rodriguez-Quesada-Rodriguez.pdf.jpgIM Thumbnailimage/jpeg6566https://www.kerwa.ucr.ac.cr/bitstreams/d06027b5-870f-49bd-a911-bc17951f472e/download6c7e3c64c1812c4dcc1303d5864283e8MD5410669/905632024-08-22 09:23:45.789open.accessoai:kerwa.ucr.ac.cr:10669/90563https://www.kerwa.ucr.ac.crInstitucionalhttp://www.kerwa.ucr.ac.crUniversidadhttp://www.ucr.ac.crhttps://kerwa.ucr.ac.cr/oai/requestmeilyn.garro@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:18712025-03-29T18:11:49.796Kérwá -
