Alteromonas macleodii str. 'Deep ecotype'

Names Alteromonas macleodii str. 'Deep ecotype'
Accession numbers NC_011138
Background Alteromonas macleodii is a common marine heterotrophic gamma-proteobacterium. Isolates cluster by molecular analysis into two major genotypic groups or ecotypes, one found in temperate latitudes in the upper water column and another that is for the most part found in the deep water column of the Mediterranean. This strain is one of the latter, having been isolated from 1000 m in the Eastern Mediterranean. Comparison with the type strain ATCC 27126, a representative of the surface water ecotype, indicates that strain DSM 17117 / Deep ecotype (AltDE) is probably better suited to microaerophilic conditions and for the degradation of recalcitrant compounds such as urea. These, together with other features, and the distribution of this genotypic group, indicate that this microbe colonizes relatively large particles that sink rapidly to meso and bathypelagic depths. The genomic data are consistent with a picture of incipient speciation driven by niche specialization (adapted from PubMed 18670397). (EBI Integr8)
