A chemically defined medium, LD82, was formulated for in vitro cultivation of spiroplasmas. Medium LD82 supported good growth for four epiphytic and insect-pathogenic spiroplasmas, Spiroplasma floricola 23-6, Spiroplasma sp. strain SR3, Spiroplasma sp. strain brevi, and Spiroplasma sp. strain AS576, and of the phytopathogenic spiroplasmas Spiroplasma citri Maroc R8A2 and PC1. Titers of all six ...

This work deals with taxonomy, geographical distribution as well as known ecology of oribatid mites of the genus Conchogneta Grandjean, 1963 in the world. The majority of species belonging to this genus is known to be widely distributed in Europe, but only three of them are found in other areas of the northern hemisphere. Most species of Conchogneta are inhabitants of litter of various types of...

Next to the benthic and pelagic compartments, the epiphyton of submerged macrophytes may offer an additional niche for ammonia-oxidizing bacteria in shallow freshwater lakes. In this study, we explored the potential activities and community compositions of ammonia-oxidizing bacteria of the epiphytic, benthic, and pelagic compartments of seven shallow freshwater lakes which differed in their tro...

Fifteen spiroplasma strains, representing five serological subgroups classified in three distinct serogroups, and four strains unassigned to serogroups were examined for sensitivity to antibiotics. The data contribute to the characterization of spiroplasmas and enlarge comparisons between plant pathogenic strains and strains that are evidently a part of the normal epiphytic microflora.

The absolute configuration of the chiral center at the C15 position of a novel branched-chain fatty acid derived from a new ceramide isolated from the epiphytic dinoflagellate Coolia monotis was determined to be of R from by reversed-phase HPLC after cleavage to 12-methylpentadecanoic acid and subsequent conversion with the chiral fluorescent reagent, (1R,2R)-2-(2,3-anthracenedicarboximido)cycl...
