Mats consisting of the large sulfide-oxidizing bacterium, Beggiatoa, were collected from the sediment/water interface at several locations in the Gulf of Mexico. The collection sites were associated with the presence of petroleum hydrocarbons or the

Larvae of the mayfly ( Drunella grandis [Eaton]) from Diamond Fork Creek, Utah, were covered with a heavy growth of the sulfide-oxidizing bacterium Thiothrix. The bacterium did not seem to harm the mayfly, but the Thiothrix trichomes were parasitized

A fluence-dependent fluorescence technique was used to observe reverse intersystem crossing from a certain higher-lying triplet state of rose bengal populated by a single pulse of 532 nm light. The quantum yield of reverse intersystem crossing from t

A group of Beggiatoa-like organisms which do not deposit sulfur from sulfide but which were isolated from the same locations as sulfide-oxidizing beggiatoas should be considered as a species within the genus Vitreoscilla. These organisms fit the gene

Two strains of Thiothrix nivea were examined to determine their morphological and physiological features. Microculture studies revealed the production of gliding gonidia and possible mechanisms for rosette formation. The strains were able to use only

Two new methane-producing cocci have been isolated from separate sediment enrichments using a defined synthetic growth medium. A freshwater methanogen, Methanogenium olentangyi, sp. nov., was isolated from Olentangy River sediment, Columbus, Ohio. Th

The type strains of the three currently recognized species of the genus Microcyclus Orskov 1928 (M. aquaticus Orskov, strain ATCC 25396; M. major Gromov, strain BKM 859; and M. flavus Raj, strain ATCC 23276), together with strains apparently belongin

The sulfur inclusions from four strain ofBeggiatoa alba were observed by using a ruthenium red-glutaraldehyde technique and a modified Ryter-Kellenberger technique. Three of the four strains contained 4-to 5-nm-thick, single, electron-dense, layered
