The overall objective is to understand the role of bacteria in decomposition of phytoplankton biomass and the importance of this process in the trophic dynamics and movement of toxic substances through Chesapeake Bay. Specific objectives are to analyze biochemically and microbiologically suspended phytodetritus, estimate bacterial production derived from decomposition of phytodetritus in the mesohaline and oligohaline regions of the Bay, and investigate the utilization of particulate substrates by bacteria in laboratory model systems.
