Cytophaga That Kills or Lyses Algae

Abstract

A myxobacterium (Cytophaga N-5) isolated from sewage kills or lyses an array of living green and blue-green algae. When assayed with Nostoc muscorum or Plectonema boryanum, plaques form like those caused by the blue-green algal virus LPP-1. This isolate lyses or inhibits mutually Gram-positive and Gram-negative eubacteria.
