| distribution and diversity of bacteria in a saline meromictic lake as determined by pcr-dgge of 16s rrna gene fragments. | the variations in vertical distribution and composition of bacteria in the meromictic lake faro (messina, italy) were analysed by culture-independent methods in two different mixing conditions. water samples were collected from a central station from the surface to the bottom (30 m depth) on two different sampling dates--the first characterised by a well-mixed water mass and the second by a marked stratification. a 'red-water' layer, caused by a dense growth of photosynthetic sulphur bacteria, w ... | 2011 | 20544199 |
