Diversidad bacteriana en el biocátodo reductor de Cr(VI) de una Celda de Combustible Microbiana con puente salino
Bacterial diversity in the Cr(VI) reducing biocathode of a Microbial Fuel Cell with salt bridge

Revelo Romo, Dolly Margot; Hurtado Gutiérrez, Nelson Humberto; Ruiz Pazos, Jaime Orlando; Pabón Figueroa, Lizeth Vanessa; Ordóñez Ordóñez, Leidy Alejandra.
Rev. argent. microbiol; 51 (2), 2019
Although Cr(VI)-reducing and/or tolerant microorganisms have been investigated, there is no detailed information on the composition of the microbial community of the biocathode microbial fuel cell for Cr(VI) reduction. In this investigation, the bacterial diversity of a biocathode was analyzed using 454 ...

Effects of volatile fatty acids in biohydrogen effluent on biohythane production from palm oil mill effluent under thermophilic condition

Mamimin, Chonticha; Prasertsan, Poonsuk; Kongjan, Prawit; O-Thong, Sompong.
Electron. j. biotechnol; 29 (), 2017
Background: Biohydrogen effluent contains a high concentration of volatile fatty acid (VFA) mainly as butyric, acetic, lactic and propionic acids. The presence of various VFAs (mixture VFAs) and their cooperative effects on two-stage biohythane production need to be further studied. The effect of VFA con...

Braz. j. microbiol; 47 (3), 2016
ABSTRACT An analysis of wastewater samples collected from different industrial regions of Egypt demonstrated dangerously high levels of nickel (0.27-31.50 mg L-1), chromium (1.50-7.41 mg L-1) and zinc (1.91-9.74 mg L-1) in the effluents. Alarmingly, these heavy metals are among the most toxic knownones t...

Medios de cultivo económicos para la producción de un biocatalizador a células enteras para el tratamiento de aguas residuales que contienen Cr(VI)
Economical fermentation media for the production of a whole cell catalyst for the treatment of Cr(VI)-containing wastewaters

Alessandrello, Mauricio J; Vullo, Diana L.
Rev. argent. microbiol; 48 (3), 2016
The biotechnology sector is continually seeking sustainable and more economical bioprocesses. Fermentation media produced with cheap components or wastes reduce production costs. Moreover, if wastes are used, they contribute to avoid environmental pollution. In this work, microbial growth media based on ...

Aeromonas species research in samples of water and beef obtained at industrial level

Rossi Júnior, Oswaldo Durival; Santos, lacir Francisco dos; Amaral, Luiz Augusto do; Barbosa, Andrea Magalhães.
Rev. bras. ciênc. vet; 3 (3), 1996
The presence of bacteria of the genus Aeromonas in food of animal origin has been demonstrated by several authors. Among the most often cited foods are those which, during their preparation, come into contact with water which is considered to be the habitat of different species and the major source of fo...
