  • VIRUS CAPABLE OF SPECIFICALLY INFECTING, GROWING WITHIN, AND LYSING RED TIDE PLANKTON; A METHOD AND AN AGENT FOR PREVENTING RED TIDE USING THE VIRUS; A METHOD FOR ISOLATING THE VIRUS; AND A METHOD FOR SUBCULTURING THE VIRUS
    Patent number: 6544928
    Abstract: The present invention provides a virus capable of specifically infecting and growing within a member of algae Heterocapsa sp. A method for isolating the above virus comprises a process of: filtrating with a filter a liquid sample containing a member of algae Heterocapsa sp. infected with a virus capable of specifically infecting and growing within said Heterocapsa sp.; inoculating the obtained filtrate into a culture solution of a member of algae Heterocapsa sp. and culturing; and cloning the above virus by performing a limiting dilution for a culture solution wherein said Heterocapsa sp. is observed to be lysed. The present invention provides an agent for preventing red tide, which comprises, as an active ingredient, the above virus. Furthermore, the present invention provides a method for preventing red tide, which comprises dispersing the above virus in red tide fouled-waters.
