In the present study, bacteria were enriched in
the culture medium supplemented with the cell
walls of P. porphyrae and screened for degrading
activity against the fungal cell walls. Then, from
these positive bacteria, we attempted to identify
the glycosyl hydrolases that were associated with
the Pythium-degrading activities. Also, the molecular
weight of each glycosyl hydrolase was estimated
as such information would be of use for
gene cloning, which would be the first biotechnological
step to establishing a new Porphyra
seedling that was resistant to Pythium sp
