Community analysis of a mercury hot spring supports occurrence of domain-specific forms of mercuric reductase

Article Abstract:

The naturally occurring mercury-rich geothermal environment is analyzed to assess the distribution of the forms of mercuric reductase (MerA) in an interacting community comprising members of both prokaryotic domains. The results have shown that MerA retains the two distinct prokaryotic forms and avoids genetic homogenization despite environmental selection for mercury resistance and the proximity of community members.

Single-cell protein profiling of wastewater enterobacterial communities predicts disinfection efficiency

Article Abstract:

This article discusses the impact of primary and secondary wastewater treatment on the physiology of enterobacterial community by protein profiling of the growth-related protein, Fis, and the stationary-phase protein, Dps, at single-cell levels. Data indicate that enterobacterial community differences in Fis and Dps measure disinfection efficiency.

Culture-independent analysis of fecal enterobacteria in environmental samplesby single-cell mRNA profiling

Article Abstract:

The single-cell mRNA profiling, a culture-independent method, is developed for the analysis of fecal enterobacteria and their physiological status in environmental samples. The mRNA profiling provides a new strategy to improve wastewater disinfection efficiency by accelerating water quality analysis.
