“…The Betaproteobacteria family Comamonadaceae was detected as the most abundant in all samples. Comamonadaceae include psychrophilic and thermophilic species, freshwater oligotrophic, as well as heterotrophic organisms capable of denitrification and metabolization of complex organic pollutants ( Zhang et al., 2013 ; Willems, 2014 ). Comamonadaceae species contributes to a stable consortium for sulfur-driven iron reduction combined with anaerobic ammonium oxidation via simultaneous nitrification and denitrification ( Bao and Li, 2017 ).…”

In November 2015, two iron ore tailing dams collapsed in the city of Mariana, Brazil. The dams' collapse generated a wave of approximately 50 million m 3 of a mixture of mining waste and water. It was a major environmental tragedy in Brazilian history, which damaged rivers, and cities 660 km away in the Doce River basin until it reached the ocean coast. Shortly after the incident, several reports informed that the concentration of metals in the water was above acceptable legal limits under Brazilian laws. Here the microbial communities in samples of water, mud, foam, and rhizosphere of Eichhornia from Doce River were analyzed for 16S and 18S rRNA-based amplicon sequencing, along with microbial isolation, chemical and mineralogical analyses. Samples were collected one month and thirteen months after the collapse. Prokaryotic communities from mud shifted drastically over time (33% Bray-Curtis similarity), while water samples were more similar (63% Bray-Curtis similarity) in the same period. After 12 months, mud samples remained with high levels of heavy metals and a reduction in the diversity of microeukaryotes was detected. Amoebozoans increased in mud samples, reaching 49% of microeukaryote abundance, with Discosea and Lobosa groups being the most abundant. The microbial communities’ structure in mud samples changed adapting to the new environment condition. The characterization of microbial communities and metal-tolerant organisms from such impacted environments is essential for understanding the ecological consequences of massive anthropogenic impacts and strategies for the restoration of contaminated sites such as the Doce River.

“…The genus Comamonas comprised 16 species with validly published names at the time of writing. According to the description of the genus (De Vos et al , 1985; Tamaoka et al , 1987; Willems et al , 1991a; Zhang et al , 2013), cells of members of the genus are Gram-stain-negative, aerobic or facultatively anaerobic straight or curved rods or spirilla, and are motile by means of polar or bipolar tufts of one to five flagella [however, the cells of Comamonas koreensis (Chang et al , 2002) and Comamonas zonglianii (Yu et al , 2011) are non-motile]. Members of the genus accumulate poly-β-hydroxybutyrate.…”

A bacterial strain, designated GAU11 T , was isolated from soil in Japan. Cells of the strain were Gram-stain-negative, aerobic, non-motile rods. The 16S rRNA gene sequence of strain GAU11 T showed high similarity to those of Comamonas zonglianii BF-3 T (98.8 %), Pseudacidovorax intermedius CC21 T (96.4 %), Acidovorax caeni R-24608 T (96.2 %), Alicycliphilus denitrificans K601 T (96.2 %), Pseudorhodoferax soli TBEA3 T (95.9 %) and Comamonas terrigena LMG 1253 T (95.9 %). Strain GAU11 T contained ubiquinone 8 as the sole ubiquinone and diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol as major polar lipids. Its major cellular fatty acids were C 16 : 0 , C 18 : 1 v7c and summed feature 3 (C 16 : 1 v7c and/or iso-C 15 : 0 2-OH). The DNA G+C content of strain GAU11 T was 68.2 mol%. The DNA-DNA relatedness between strain GAU11 T and C. zonglianii DSM 22523 T was 52 or 68 % (reciprocal value). Phenotypic characterization indicated that strain GAU11 T represents a member of the genus Comamonas, but at the same time distinguished it from C. zonglianii DSM 22523 T . From polyphasic characterization, this strain should be classified as representing a novel species of the genus Comamonas, for which the name Comamonas humi sp. nov. (type strain GAU11 T 5JCM

“…The species of the genus Comamonas have been isolated from a wide variety environments, such as food waste compost, wetlands, the gut of a termite, landfill leachate, sludge and soil, etc . (Chang et al , 2002; Chou et al , 2007; Kim et al , 2008; Tago & Yokota, 2004; Young et al , 2008; Yu et al , 2011; Zhang et al , 2013). In the present study, the taxonomic position of an isolate belonging to the genus Comamonas was determined; SP-35 T was isolated from the wheat straw compost as an aromatic compounds degrader.…”

“…S2). The closest phylogenetic relative, C. guangdongensis CY01 T , contained diphosphatidylglycerol, phosphatidylethanolamine, an unknown aminolipid and an unknown phosphatidylglycerol, but absent phosphatidlyglycerol as the typical polar lipids (Zhang et al , 2013). These results further proved that strain SP-35 T represents a novel species within the genus Comamonas .…”

A Gram-stain-negative bacterium, designated SP-35T, was isolated from compost and was subjected to a taxonomic study. This isolate was short-rod-shaped and non-spore-forming. Phylogenetic analysis based on 16S rRNA sequence comparison indicated the isolate was related to the genus Comamonas . 16S rRNA gene sequence analysis showed that its closest neighbours were the type strains Comamonas odontotermitis Dant 3-8T (96.8 % similarity), Comamonas testosteroni DSM 50244T (96.5 %), Comamonas guangdongensis CY01T (95.9 %) and Comamonas composti YY287T (95.6 %). Using phylogenetic analysis, DNA–DNA hybridization, fatty acid composition data and a range of physiological and biochemical characteristics we could clearly distinguish strain SP-35T from type strains of the genus Comamonas . The genomic DNA G+C content of strain SP-35T was 63.1 mol%. The predominant cellular fatty acids were C16 : 0, C17 : 0 cyclo, summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c). The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidlyglycerol. Differences in phenotypic and phylogenetic characteristics support the classification of strain SP-35T as a representative of a novel species in the genus Comamonas , for which the name Comamonas serinivorans sp. nov. is proposed. The type strain is SP-35T ( = DSM 26136T = JCM 18194T).
