zooglea, zoogloea (s) (noun), zoogleas; zoogleae (pl)
A colony of microbes embedded in a gelatinous matrix (a substance in which something is enclosed): Zooglea is a jellylike cluster of bacteria swollen by the absorption of fluids from the medium in which they are grown.

A gelatinous mass of bacterial cells produced by certain genuses, such as "Zoogloea ramigera" which is used to treat sewage.

The bacteria gradually swell up into zoogloea masses, until finally their bodies break down into soluble nitrogenous substances which are partly absorbed and assimilated and partly stored as reserve nitrogenous food by the green leguminous plant.
