Abstract

Bacteria assigned to the genus have not yet been isolated in pure culture, but have been implicated in the deposition of ferric iron. These organisms have been observed in a number of lakes but the conditions under which active growth occurred have not been defined. A population of sp. developed in the anoxic hypolimnion of Esthwaite Water, a eutrophic lake in the English Lake District. Direct counts and experimental evidence obtained with this population suggested that the organism was capable of anaerobic growth. Inhibition of growth by chloramphenicol provided further evidence of its prokaryotic organization. The population overwintered in the sediment and at the onset of summer stratification, with deoxygenation of the hypolimnion, migrated into the water column. There was insufficient evidence to implicate sp. in ferric iron deposition.
