Project Title: 

An Investigation of the Role of Bacteria and Heterotrophic Flagellates in the Trophic Structure of the Salt Marsh-Bacterial Clumping

Abstract: 

The occurrence of bacterial clumping in marine systems was investigated as related to the presence of flagellate predators. The factors of movement, bacterial concentration, and flagellate species were included in this investigation. The flagellate Bodo parvulis was found to cause clumping in a strain of bacteria isolated from Canary Creek in Lewes, Delaware. The role of Bodo was explored in the clumping process with specific regard to exopolymer secretions and the trophic dynamics possibly affected by them.
