More recently, Rieper (1976) showed that the growth of a fraction of the bacterial population in the Schlei Fjord (Baltic Sea) is enhanced by actively growing cells of Chlorella spp., whereas other bacteria are inhibited by the same algae at the termination of their spring bloom (Fig. 4). In the late summer a symbiotic or mutualistic relationship exists between other bacteria and the alga Microcystis aeruginosa.

Microginins, a main class of cyanobacte-rial peptides from Microcystis, Planktothrix, and Nostoc. The linear peptides vary in length from four to six amino acids, contain a C-terminal 3-amino-2-hydroxy-decanoic acid moiety (Ahda), and two tyrosine units at the C-terminus. The first member was isolated from the freshwater blue-green alga Microcystis aeruginosa (NIES-100), and is an inhibitor of angiotensin-converting enzyme [T. Okino et al.. Tetrahedron Lett.

Results such as those shown in Fig. 2 must be compared to expected impacts in order to determine possible courses of action such as closing down water intakes or the like. Additionally, other harmful effects can be anticipated based on a knowledge of reaction to a given level of the material. For example, Cox and Boardman (15) have shown that the blue-green alga. Microcystis aeruginosa, notorious for the obnoxious nature of its bloom, are strongly influenced by introduction of herbicides. Two commonly used phenoxy-carboxylic herbicides,...
