1.7.2.7 | evolution |
for ammonia-oxidizing bacteria, a major shift from Candidatus Brocadia fulgida to Candidatus Kuenenia stuttgartiensis in both suspension and biofilm was observed with progressively shorter HRT, using discriminatory biomarkers targeting the hydrazine synthase (hzsA) gene is determined in biofilm analysis. Directed differentiation between the biofilm and suspension is observed in the molecular microbial ecology and gene expression of different bacteria in a biofilm nitritation-anammox process operates at varying hydraulic residence times and nitrogen loading rates |

1.7.2.7 | evolution |
metagenomic analysis of diagnostic genes encoding key enzymes involved in the nitrogen cycle in in situ microbial community in an oligotrophic, brackish environment of the Bothnian Sea sediment, overview. Metagenome analysis reveals higher hzsA gene read abundance in sulfate methane transition zone (SMTZ, 2.4) than in oxic/anoxic interface zone (OAZ, 0.6). The hza sequences show high similarity to uncultured Scalindua spp. originating from the marine sediments in Guyamas Basin (AGV76990) |

1.7.2.7 | physiological function |
hydrazine biosynthesis is catalysed by enzyme Hzs. The cells metabolize hydrazine as an intermediate of the anammox process. Hydrazine biosynthesis from NH4+ and hydroxylamine, hydrazine accumulates in the culture concurrently with consumption of hydroxylamine. Hydrazine accumulation continues until hydroxylamine is depleted. Thereafter, hydrazine concentration gradually decreases. Ca. Jettenia caeni cells synthesize hydrazine with the consumption of hydroxylamine |
