Vorticella convallaria is a polymorphic, ciliated protozoan that spends the majority of its life cycle as an actively-feeding, sessile cell attached to a substrate by its contractile stalk (Fig.
In their review of biological springs and ratchets, Mahadevan and Matsudaira (2000) describe the spasmoneme spring of Vorticella, which contracts in response to calcium signaling and can propel the cell body at speeds of about 8 cm/s.
They were interspersed with massive growths of Epistylis sp., Carchesium sp., Vorticella sp., Stentor sp., Sinantherina socialis, Urnatella gracilis, and encrusting bryozoans.
Se observo la presencia de ciliados peritricos coloniales identificados como Epistylis y Vorticella spp., asi como se confirmo la ocurrencia de los ciliados suctorios Acineta y Tokophrya spp.
With respect to taste and odor control, there are a number of studies reporting on the successful use of chlorine dioxide in the treatment of musty odors, fishy tastes and odors from Mallonmonas, and taste and odor problems associated with Anabaena, Asterionella, Synura, and Vorticella, as well as actinomycetes which are a source of geosmin and 2-methylisoborneol (MIB).|3,4,5~ A 1986 study which compared chlorine dioxide, chlorine, ozone, and potassium for removal of five specific taste and odor compounds from drinking water found removals ranging from 30 to over 50 percent for practical Cl|O.sub.2~ dosages and contact times.|6~ Chlorine dioxide has also been shown to be effective for treating tastes and odors associated with phenol and phenolic compounds.|7,8,9~
