Composite FISH micrographs of activated sludge from a lab-scale reactor. “Ca. Propionivibrio aalborgensis” cells appear white having hybridized with Prop207(green), PAOmix(red) and EUBmix (blue); “Ca. Accumulibacter sp.” appear magenta with their cells hybridizing the PAOmix and EUBmix probes ets; all other cells hybridized with EUB mix only and appear blue. Scale bar represents 20 microns. - Source:1

Description

The Propionivibrio are suggested to behave as typical GAO in EBPR systems. This is supported by their storage of volatile fatty acids as PHA under anaerobic conditions without excess polyphosphate storage 1. Most of the isolates of the Propionivibrio genus are anaerobic to aero-tolerant and have a fermentative metabolism producing propionate and acetate as characteristic metabolic end products 2 3 4. However, Propionivibrio militaris has a strictly respiratory metabolism, utilizing various substrates that include acetate and propionate 5.

FISH probes

Prop207 targets the species "Ca. Propionivibrio aalborgensis" only. However, this appears to represent the abundant species in full-scale systems and the probe is therefore considered relevant for coverage of the genus in activated sludge 1.
