Detection of microbial biomass by intact polar membrane lipid analysis in the water column and surface sediments of the Black Sea.

abstract：:Phosphonoacetate is regarded as an antiviral xenobiotic whose mineralization can be catalysed by an enzyme, phosphonoacetate hydrolase, encoded by the phnA gene. To date the enzyme's activity has been detected in only a limited number of bacteria. Its expression has been shown to occur in a manner independent of the p...
