Aerotaxis in Desulfovibrio

Environmental Microbiology, 1999
Aerotaxis of two sulphate‐reducing bacteria, the freshwater strain Desulfovibrio desulfuricans CSN (DSM 9104) and the marine strain Desulfovibrio oxyclinae N13 (DSM 11498), was studied using capillary microslides, microscopy and oxygen microsensors. The bacteria formed ring‐shaped bands in oxygen diffusion gradients surrounding O2 bubbles, which were ...

The primary pathway for lactate oxidation in Desulfovibrio vulgaris

Frontiers in Microbiology, 2015
The ability to respire sulfate linked to lactate oxidation is a key metabolic signature of the Desulfovibrio genus. Lactate oxidation by these incomplete oxidizers generates reductants through lactate dehydrogenase (LDH) and pyruvate-ferredoxin ...

Isolation of Desulfovibrio spp. from human gut microbiota using a next‐generation sequencing directed culture method

Letters in Applied Microbiology, 2019
Desulfovibrio spp. is predominant member of sulphate‐reducing bacteria in human gut microbiota. Previous studies indicated that the isolation of Desulfovibrio strains from human faecal samples is very important to study the roles of human intestinal ...

[22] Genetic manipulation of Desulfovibrio

1994
Publisher Summary This chapter describes genetic manipulation of Desulfovibrio. In several cases, it has been observed that expression in Escherichia coli ( E. coli ) of genes for Desulfovibrio metal proteins results in the accumulation of apoproteins, sometimes as insoluble complexes without the metal (clusters) incorporated, because of the lack

Toxic effects of dissolved heavy metals on Desulfovibrio vulgaris and Desulfovibrio sp. strains

Journal of Hazardous Materials, 2006
Biological treatment of metal-containing wastewaters with sulphate-reducing bacteria (SRB) is an attractive technique for the bioremediation of this kind of medium. In order to design a suitable engineering process to address this environmental problem, it is crucial to understand the inhibitory effect of dissolved heavy metals on these bacteria. Batch

Bacteremia caused by Desulfovibrio fairfieldensis

Journal of Infection and Chemotherapy, 2008
Desulfovibrio species are anaerobic gram-negative, pleomorphic bacilli rarely causing infection in humans. In the present report, we describe a case of bacteremia caused by Desulfovibrio fairfieldensis. The patient, for whom biapenem was administered, rapidly improved without any sequelae.

A re-examination of Desulfovibrio africanus

Archiv f�r Mikrobiologie, 1971
Contrary to previous descriptions of its properties (Campbell et al., 1966; Postgate and Campbell, 1966) Desulfovibrio africanus was found to be bipolarly flagellate, frequently semi-annular in shape and to contain, in addition to a reported soluble c-type cytochrome, particulate oxido-reducible pigments indicative of b-, c-and d-type cytochromes.

Characterization of Recombinant Desulfovibrio gigas Ferredoxin

Biochemical and Biophysical Research Communications, 2001
Dg ferredoxin gene was cloned using the polymerase chain reaction (PCR), inserted into vector pT7-7, and overexpressed in Escherichia coli (E. coli) grown in aerobic media. The recombinant protein is a dimer and contains a [3Fe-4S] cluster per monomer. EPR and (1)H NMR data of recombinant and wild-type protein are compared.

Membrane protein complex of APS reductase and Qmo is present in Desulfovibrio vulgaris and Desulfovibrio alaskensis

Microbiology, 2013
Due to their adjacent location in the genomes of Desulfovibrio species and their potential for formation of an electron transfer pathway in sulfate-reducing prokaryotes, adenosyl phosphosulfate (APS) reductase (Apr) and quinone-interacting membrane-bound oxidoreductase (Qmo) have been thought to interact together during the reduction of APS.

Periplasmic oxygen reduction by Desulfovibrio species [PDF]

Archives of Microbiology, 2001
Washed cells of Desulfovibrio vulgaris strain Marburg (DSM 2119) reduced oxygen to water with H(2) as electron donor at a mean rate of 253 nmol O(2) min(-1) (mg protein)(-1). After separating the periplasm from the cells, more than 60% of the cytochrome c activity and 90% of the oxygen-reducing activity were found in the periplasmic fraction.
