Abstract
Several filamentous bacteria belonging to the phototrophic green bacteria have been described so far. Chloroflexus aurantiacus (Piersor. and Castenhotz, 1974) is a gliding, unbranched, multicellular bacterium occurring in hot springs. It contains BChls a and c and is able to grow aerobically in the light or dark as well as anaeroblcally in the light. As mesophilic representatives of the multicellular filamentous green bacteria two species, Chloronema giganteum and Cn. spiroideum, were isolated by Dubinina and Gorlenko (1975). Both species contain gas vacuoles and show gliding motility. They contain BChl c or d and seem to be organotrophic. Finally, a unicellular, gliding bacterium, Chloroherpeton thalassium (Gibson et al., 1964) was isolated from marine habitats. As a member of the green sulfur bacteria it is obligately phototrophic and contains BChl c and γ-carotene as the major photosynthetic pigments. Gas vacuoles have been observed in most strains.
