Differential responses of marine, mesohaline and oligohaline bacterial communities to the addition of terrigenous carbon.

abstract：:The activated sludge process relies on the formation of strong microbial flocs. The knowledge about dominant floc-forming bacteria is at present very limited, especially from a phylogenetic perspective. In this study, numerous microcolonies in the activated sludge flocs were found to be targeted by a Betaproteobacteri...

abstract：:Upon a wide range of stress conditions (e.g. nutrient, antibiotic, oxidative), a subpopulation of bacterial cells known as persisters survives by halting metabolism. These cells resuscitate rapidly to reconstitute infections once the stress is removed and nutrients are provided. However, how these dormant cells resusc...
