Enumeration of particle-bound and unattached respiring bacteria in the salt marsh environment.
Proportions of respiring bacteria determined with a 2-(p-iodophenyl)-3-(p-nitrophenyl)-5-phenyl tetrazolium chloride dye-epifluorescent technique were significantly elevated in the 300-mum surface layer of a salt marsh estuary. Almost all the detectably respiring bacteria in the particle-laden surface layer and a significant proportion in subsurface waters were attached to particles.
