Neomicrothrix subdominans sp. nov.

Submitted by Nielsen, Per Halkjær

Species Neomicrothrix subdominans

Etymology
[sub.do'mi.nans.] L. prep. sub, below; L. pres. part. dominans, dominant; N.L. fem. part. adj. subdominans, indicating the abundance of this organism often below the dominant species Neomicrothrix parvicella
Nomenclatural type
NCBI Assembly: GCA_016719385.1 Ts
Description
Filamentous bacteria commonly found in municipal activated sludge WWTPs. The species was defined based on phylogenomic and 16S rRNA-based phylogenetic analysis. The filaments are 1.0 ± 0.2 µm wide and 98 ± 19 µm long. Its is a heterotroph and has a potential to reduce nitrate to nitrite. Based on metabolic potential they could consume long chain fatty acids and can accumulate and store lipids under both aerobic and anaerobic conditions. In situ analysis showed that they are able to store poly-P, but to not cycle it.
