Isolation and Identification of Sulphite- and Iron Reducing, Hydrogenase Positive Facultative Anaerobes from Cooling Water Systems

Genome Sequence of Aeromonas hydrophila ATCC 7966 T : Jack of All Trades

“…This dissimilatory sulfate reduction activity, while rare outside the sulfate-reducing bacteria, was previously reported for Aeromonas spp. isolated from industrial cooling water systems and implicated in microbially influenced corrosion (71). Other electron acceptor sources utilized by A. hydrophila (which may be deduced from the genome sequence) include tetrathionate, fumarate, and trimethyl-Noxide.…”

Role of the reversible electrochemical deprotonation of phosphate species in anaerobic biocorrosion of steels

“…It has been widely demonstrated that sulphate reducing bacteria (SRB) play a major role in the anaerobic microbially influenced corrosion (MIC) of carbon steels [1][2][3][4][5][6] and stainless steels [7][8][9]. The mechanisms proposed to explain anaerobic MIC by SRB include: precipitation of iron sulphide, which next catalyzes proton reduction into molecular hydrogen and acts as a cathode in a galvanic couple with metallic iron [10][11][12]; catalysis of the reduction reaction by a hydrogenase enzyme coming from the bacteria [13]; anodic depolarization resulting from the local acidification at the anode [14]; metal ion chelating by extra cellular polymer substances (EPS) [15] and galvanic coupling with EPS [16].…”

Evolutionary and Diagnostic Implications of Intragenomic Heterogeneity in the 16S rRNA Gene in Aeromonas Strains

“…media clade that has a 77% bootstrap support value or within a large clade that contained Aeromonas encheleia, Aeromonas eucrenophila, and other species with a 75% bootstrap value. Al- (10,21) suggests that at least 21% had intragenomic heterogeneous SSU alleles as determined by the presence of faint bands that could not be removed by adding more restriction enzyme (data not shown) indicating that SSU heterogeneity is not a rare phenomenon in this genus. Our results suggest that the SSU sequences may not properly reflect the taxonomic relationship of these strains and are not the best choice for identifying Aeromonas species (10).…”
