Contribution of Particle-Bound Bacteria to Total Microheterotrophic Activity in Five Ponds and Two Marshes

摘要: We examined the abundance and heterotrophic uptake of bacteria attached to particulate matter suspended in five coastal ponds two marshes near Woods Hole, Mass. Although number particle-bound was low ( 40%) [14C]glucose [14C]glutamate selected aquatic systems. The per cell significantly higher for epibacteria than unattached all Two groups environments sampled were statistically different contribution made by total bacterial assimilation [14C]glutamate. Particle-bound more important those waters with a high particle concentration not flushed regularly tides regularly.
