Algae as Natural Antagonists of Pathogenic Bacteria in Water Ecosystems (Experimental Model of Algal-Bacterial Relationships )

Abstract

The allelopathic effect of the freshwater alga <i>Chlorella vulgaris</i> on growth of the pathogenic microorganisms <i>Erysipelothrix rhusiopathiae</i> and <i>Leptospira interrogans</i> - pathogens of human and animals was studied. The excretion by <i>Chlorella vulgaris</i> inhibited growth of the experimental samples of pathogenic microorganisms in all range of dilutions (1:100, 1:100, 1:1000). The freshwater alga <i>Ch. vulgaris</i> is promising for remediation of wetlands from pathogenic microorganisms, particularly <i>E. rhusiopathiae</i> and <i>L. interrogans</i>.
