Control of Algae With Viruses

摘要: CURRENTLY, growths is almost the control entirely of algae degrowths almo t dependent upon use copper sulfate and chlorine, although neither agent selectively toxic or completely effective. The fact that treatment seldom aimed at specific involved, but rather annihilation total population, may lead to complete disruption biologic community thereby seriously affect aquatic environment. It is, therefore, evident methods should differentiate between nuisance organisms those causing little no problem. ultimate objective such an approach replacement with more desirable species. success method would depend on agents have capacity induce ecologic succession in algal As a result extensive chemical screening programs, discoveries algicidal are being reported increasing numbers.1-6 Many these new selective, but, for variety reasons, none has been widely accepted. Under circumstances, it appear controlling undesirable needed. On basis evidence accumulated during previous studies,1' 7 seemed reasonable assume cells susceptible viral infections. With this relationship virus mind, investigation was inaugurated eventually led isolation blue-greenalgae (BGA) authors' knowledge, first definite viruses infect destroy fresh-water algae.8 This discovery not only represents tool fundamental research field
