A nitrogen-fixing consortia associated with the bacterial decay of a wooden pipeline
journal contribution
posted on 2023-05-16, 10:26 authored by Line, MAInvestigation of superficial decay of 2.0 m diameter wooden pipeline carrying water for hydroelectric power generation, revealed the presence of a wood-decaying, nitrogen-fixing bacterial consortia associated with the attack. The most severe attack occurred in pools of semi-permanent water on the top of the pipeline. Associated N2-fixing biota were identified as Xanthobacter autotrophicus or X. flavus, Pseudomonas acidovorans, Ps. alcaligenes, Ps. aureofaciens and an Alcaligenes sp. The Alcaligenes and Pseudomonas isolates (but not the Xanthobacter isolates) showed growth with creosote as the sole source of carbon, with gas chromatography/mass spectrometry analysis indicating utilization of the aliphatic components in the C22-C35 range.
