TīmeklisThe abundance of these phages may be related to the extensive growth of autotrophic microbial mats around the contours of the hot spring, which may sustain a release of these phages in the surrounding water column. Table 2. Most represented bacteriophage isolate genomes in the Brandvlei metavirome.
