Abstract: | Twenty-five strains of epiphytic marine bacteria isolated from the brown algaeFucus evanescens andChorda filum and fifty-three bacteria isolated from the sea cucumberApostichopus japonicus were screened for fucoidanases using fucoidans prepared from the brown algaeF. evanescens, Laminaria cichorioides, andL japonica. Eighteen bacterial epiphytes and thirty-eight bacterial isolates from the sea cucumber were found to contain fucoidanases,
which were able to hydrolyze either all of the fucoidans studied or some of them. Bacteria of the generaCytophaga andAlteromonas/Pseudoalteromonas exhibited the highest fucoidanase activities, which, however, did not exceed the activity of fucoidanases from the already
known sources. |
