Structural redox control in a 7Fe ferredoxin isolated from Desulfovibrio alaskensis
(Elsevier, 2011-04)
The redox behaviour of a ferredoxin (Fd) from Desulfovibrio alaskensis was characterized by electrochemistry. The protein was isolated and purified, and showed to be a tetramer containing one [3Fe–4S] and one [4Fe–4S] ...
A Kinetic Analysis of Microbial Sulfate Reduction in an Upflow Packed-Bed Anaerobic Bioreactor
(Brasil, 2012)
The effects of initial sulfate concentration on anaerobic sulfate reduction and sulfide generation kinetics were investigated in an up-flow bioreactor, using a consortium of sulfate-reducing bacteria (SRB) from water ...
Isolamento e identificação molecular de bactérias redutoras de sulfato de amostras de água produzida em campo de petróleo
(Instituto de Ciências da Saúdeem BiotecnologiaUFBAbrasil, 2016-01-08)
As bactérias redutoras de sulfato (BRS) são microrganismos responsáveis
por diversos problemas em sistemas de água em campos petrolíferos, acarretando
em elevados prejuízos econômicos. A identificação das BRS relacionadas ...
Determinación de la capacidad de los cultivos mixtos de bacterias sulfato reductoras libres e inmovilizados en perlas de gel de alginato de calcio de disminuir iones de hierro en solución
(Universidad Peruana Cayetano HerediaPE, 2020)
La contaminación por metales pesados está muy extendida en diversos ambientes y se desarrollan diversas alternativas para remediarla. Entre estas se considera el uso de microorganismos, dentro de los cuales se encuentran ...
Effect of the Protonation Degree of a Self-Assembled Monolayer on the Immobilization Dynamics of a [NiFe] Hydrogenase
(American Chemical Society, 2012-12-07)
Understanding the interaction and immobilization of [NiFe] hydrogenases on functionalized surfaces is important in the field of biotechnology and, in particular, for the development of biofuel cells. In this study, we ...
Aerobic Lineage of the Oxidative Stress Response Protein Rubrerythrin Emerged in an Ancient Microaerobic, (Hyper)Thermophilic Environment
(2016)
Rubrerythrins (RBRs) are non-heme di-iron proteins belonging to the ferritin-like superfamily. They are involved in oxidative stress defense as peroxide scavengers in a wide range of organisms. The vast majority of RBRs, ...
Evaluación de nuevas sondas de oligonucleótidos para la detección de bacterias sulfato reductoras
(Bucaramanga : Universidad de Santander, 2018Facultad de Ciencias Exactas, Naturales y AgropecuariasMicrobiología Industrial, 2018-07-16)
Sulfate reducing bacteria are the main cause of corrosion induced by microorganisms in the oil industry because they generate sulfide acid and thus are affected structures, equipment and machinery of metal, as well as crude ...
Exploring Coupled Redox and pH Processes with a Force-Field-Based Approach: Applications to Five Different Systems
(2020-02-26)
Coupled redox and pH-driven processes are at the core of many important biological mechanisms. As the distribution of protonation and redox states in a system is associated with the pH and redox potential of the solution, ...
Application of molecular techniques to evaluate the methanogenic archaea and anaerobic bacteria in the presence of oxygen with different COD : sulfate ratios in a UASB reactor
(ELSEVIER SCI LTD, 2008)
In this paper, the microbial characteristics of the granular sludge in the presence of oxygen (3.0 +/- 0.7 mg O-2 1(-1)) were analyzed using molecular biology techniques. The granules were provided by an upflow anaerobic ...
