Spatial and temporal variation of phenanthrene-degrading bacteria in intertidal sediments.

abstract：:A variant of Bacillus thuringiensis subsp. kurstaki containing a single, stable copy of a uniquely amplifiable DNA oligomer integrated into the genome for tracking the fate of biological agents in the environment was developed. The use of genetically tagged spores overcomes the ambiguity of discerning the test materia...
