FISH micrographs of the Micropruina spp. in full-scale activated sludge. Micropruina appear yellow [MGL-67 (red) + EUBmix (green)] and other bacteria green (EUBmix alone). Scale bar = 10 microns. - Source:4

POSNEGVariableNot assessed

Description

The organism is suggested to be a putative GAO as sugars and amino acids are assimilated under anaerobic conditions in the absence of excess polyphosphate storage in situ 24. Glycogen is detected but not PHA in situ 4. Further studies are required to elucidate its physiology and role in EBPR. The sole isolate of the genus, Micropruina glycogenica, was isolated from a lab-scale EBPR system. Cells are cocci, occurring in pairs, packets or clusters 1.

FISH probes

MIC184 2, MGL-67, MGL-1223 4 . Note that MIC184 hits a number of closely related genera including some sbr-gs28 and Propionicimonas. Competitor probes MGL-67C1, MGL-1223C1 and MGL-1223_C2 are recommended to be applied with their respective probes 4.
