Allelopathic Influence on Blue-Green Bloom Sequence in a Eutrophic Lake

KATHLEEN IRWIN KEATING 1

1 Department of Environmental Science, Rutgers University, New Brunswick, New Jersey 08903

The bloom sequence in a eutrophic lake, Linsley Pond, over a period of 3 years is correlated to the effects of cell-free filtrates of dominant blue-green algae on both their successors and their predecessors. There is unbroken correspondence between the effects of heat-labile probiotic and antibiotic filtrates and the rise and fall of bloom populations in situ. All organisms in vitro were axenic or unialgal (bacterized) isolates from Linsley Pond.
