Abstract
Seventy-one marine bacteria decomposing sea tangle (Laminaria japonica) into single cell detritus (SCD) were isolated from sea water, sea tangle, sea mustard (Undaria pinnatifida), sea urchin (Anthocidaris crassispina), star fish (Acanthaster planci), and turban cell (Batillus cornutus), among which 14 strains decreased cutting strength of sea tangle and had alginate-degrading activity. Marine bacterium No. 34 isolated from turban cell showed lowest cutting strength of sea tangle, strongest alginate-degrading activity, and produced high content of $5-10\;{\mu}m$ SCD from sea tangle. This strain was identified as Vibrio sp. based on morphological, physiological, and biochemical characteristics and named as Vibrio sp. YKW-34.
