description

Abstract A numerical taxonomic study was performed on 245 strains of heterotrophic, aerobic, marine bacteria, plus 26 reference strains. The isolates were obtained from oysters and seawater sampled monthly over one year, by direct plating on Marine Agar. The strains were characterised by 93 morphological, biochemical, physiological and nutritional tests. Clustering yielded 46 phena at 0.60 S level (S J coefficient). Some could be identified as species of Alteromonas, Shewanella, Deleya, Flavobacterium, Oceanospirillum, Pseudomonas and marine Agrobacterium -like organisms, others were unidentified groups. Several phena seem to correspond to as yet undescribed taxa.
