Names
Ca. Brocadia sinica
Abstract
The present study investigated the phylogenetic affiliation and physiological characteristics of bacteria responsible for anaerobic ammonium oxidization (anammox); these bacteria were enriched in an anammox reactor with a nitrogen removal rate of 26.0 kg N m−3day−1. The anammox bacteria were identified as representing ‘CandidatusBrocadia sinica’ on the basis of phylogenetic analysis of rRNA operon sequences. Physiological characteristics examined were growth rate, kinetics of ammonium oxidation

Physiological role of the respiratory quinol oxidase in the anaerobic nitrite-reducing methanotroph ‘Candidatus Methylomirabilis oxyfera’

Abstract
The anaerobic nitrite-reducing methanotroph ‘CandidatusMethylomirabilis oxyfera’ (‘Ca.M. oxyfera’) produces oxygen from nitrite by a novel pathway. The major part of the O2is used for methane activation and oxidation, which proceeds by the route well known for aerobic methanotrophs. Residual oxygen may serve other purposes, such as respiration. We have found that the genome of ‘Ca.M. oxyfera’ harbours four sets of genes encoding terminal respiratory oxidases: two cytochromecoxidases, a third put
