Spirillum

(spī-ril'ŭm),
A genus of large (1.4-1.7 mcm in diameter), rigid, helical, gram-negative bacteria (family Spirillaceae) that are motile by means of bipolar fascicles of flagella. These freshwater organisms are obligately microaerophilic and chemoorganotrophic, possessing a strictly respiratory metabolism; they neither oxidize nor ferment carbohydrates. The type species is Spirillum volutans.

Overall biological activity can be measured by the amount of carbon dioxide emitted and, more analytically, by drawing up an inventory and count of 1) the mesofauna (nematodes, annelid worms, microarthropods, arachnids, apterygote and pterygote insects, myriapods, isopod and decapod crustaceans, rotifers, tardigrades, molluscs), 2) the microbiota (protoctists and the microorganisms that perform the essential processes of denitrification, ammonification, and nitrification; the other bacteria; and microsymbionts like Rhizobium, Klebsiella, Spirillum, or Azospirillum), and 3) the mycota (fungi and lichens).
