Effects of the Extracellular Products of Enteromorpha iinza on its Epiphytic Bacterial Flora

Abstract

Yellow and orange pigmented bacteria assigned to the genus Flavobacterium-Cytohyaga were characteristically predominant on Enteromorpha linza (Linné) J. Agardh, but they did not become predominant in the solutions containing the extracellular products of the alga as sole organic carbon source. Pseudomonas was predominant in the solutions. Vibrio was present in low numbers both in the solutions and on the alga. The growth of Vibrio was inhibited by the extracellular products of the alga. The growths of Pesudomonas and Flavobacterium-Cytophaga were stimulated by the products.
