Abstract
Changes in concentration of dissolved DNA was studied in a species-defined microcosm consisting of bacteria Escherichia coli, protozoa Tetrahymena the rmophila and algae Euglena gracilis. A marked increase in dissolved DNA was observed when T thermophila grazed on E. coli and grew. This meant the pre y-predatory relationship between E. coli and T. thermophila was responsible for the increase of dissolved DNA.
