| molecular detection and ecological significance of the cyanobacterial genera geitlerinema and leptolyngbya in black band disease of corals. | black band disease (bbd) is a pathogenic, sulfide-rich microbial mat dominated by filamentous cyanobacteria that infect corals worldwide. we isolated cyanobacteria from bbd into culture, confirmed their presence in the bbd community by using denaturing gradient gel electrophoresis (dgge), and demonstrated their ecological significance in terms of physiological sulfide tolerance and photosynthesis-versus-irradiance values. twenty-nine bbd samples were collected from nine host coral species, four ... | 2007 | 17601818 |
