摘要	A newly identified bacterial disease of kelp (Saccharina japonica) gametophytes was found in clone cultures. It is characterized by swollen gametophyte cells in the early period of infection followed by filamentous fading. An alginolytic marine bacterium referred to as A-1 was isolated from the diseased gametophytes. On the basis of 16S rDNA sequencing and morphological, physiological and biochemical characteristics, the bacterium was identified as a strain of the genus Alteromonas. By testing Koch's postulates, Alteromonas sp. A-1 was further confirmed as the pathogen. The infection process was also investigated using both scanning electron and light microscopy.; A newly identified bacterial disease of kelp (Saccharina japonica) gametophytes was found in clone cultures.
