Brit.

/zəʊəˈɡliːə/, U.S.

/zu(ə)ˈɡliə/,

/zoʊəˈɡliə/

Inflections: Plural unchanged, zoogloeae, zoogloeas.

Forms: 1800s zoögloea, 1800s– zoogloea, 1900s– zooglea.

Origin: A borrowing from Latin. Etymon: Latin Zoogloea.

Etymology: < scientific Latin Zoogloea, genus name (F. Cohn 1854, in Novorum actorum Acad. Caesareae Leopold.-Carolin. Nat. Curiosorum 24 123) < zoo- zoo- comb. form + ancient Greek γλοιός glutinous substance (compare Byzantine Greek γλοία or γλοιά glue: see gloiocarp n.). Compare mesogloea n.

Microbiology.

1. In form Zoogloea: a genus of Gram-negative, aerobic, rod-shaped bacteria (family Pseudomonadaceae), typically occurring in masses or films surrounded by gelatinoid material, and often found in water containing sewage or other organic matter; (also zoogloea) a bacterium of this genus.Valid publication of the genus name: H. Itzigsohn 1868, in Sitzungs-Berichte der Gesellschaft Naturforschender Freunde zu Berlin (19 Nov. 1867) 30/2.

1861 A. Pritchard et al. Hist. Infusoria (ed. 4) 187 He [sc. Cohn] finds sufficient support from analogy to warrant him in assuming a like history for them [sc. the remaining Vibrios] as for Zooglœa.

1867 Jrnl. Bot., Brit. & Foreign 5 192 The spores of Zooglœa appear under a magnifying power of 300 to 480 as small points.

1914 Jrnl. Econ. Biol. 9 129 This zoogloea [sc. Zoogloea ramigera] is perhaps the most characteristic and important organism of this zone [of a sewage filter].

1988 H. Stolp Microbial Ecol. iii. 80 Zoogloea is ubiquitous in organically enriched oxygenated waters.

2006 Biol. Bull. 210 75/2 The characterization of some of these epibionts as species of Zoogloea is problematic.

2. A mass or film of bacteria (sometimes with other microorganisms) surrounded by gelatinoid material. Frequently attributive.

1872 Harper's Mag. Aug. 469/2 As the nitrogenous food of Bacteria is consumed they gradually cease to multiply, and pass from the movable to the quiescent condition, during which they secrete an intercellular substance, and heap this up into palmella-like masses (zooglœa).

1893 Amer. Naturalist 27 786 In Phaseolus vulgaris and Pisum sativum they [sc. Rhizobia] are often collected into Zoogloeae.

1901 F. D. Chester Man. Determinative Bacteriol. 109 Cocci [of Micrococcus cyaneus] elliptical; form zoögloea.

1946 A. Nelson Princ. Agric. Bot. xvi. 344 The furthest tip of a hair is attacked, and in favourable conditions a small gelatinous mass of the bacteria develops soon thereafter. This is the zooglœa stage.

2008 New Scientist 28 June 89/4 The passage of water through a filter leads to the build-up of a zoogloea.
