Effects of temperature and salinity on survival of toxigenicVibrio cholerae O1 in seawater.

abstract：:Generally, only a small fraction of free-living pelagic bacteria are metabolically active, while particle-associated bacteria usually exhibit a larger proportion of active bacteria. Most previous studies on the active fraction of bacteria focus on planktonic communities, and there are only a few studies on sediment an...
