Algicidal Agent Containing Prodigiosin and Prodigiosin Biosynthetic Gene Cluster

摘要

An algicidal agent containing prodigiosin and a prodigiosin biosynthetic gene cluster are provided to kill reddish brown tide-causing bacteria including Cochlodinium polykrikoides, Gyrodinium impudicum and Heterosigma akashiwo. The prodigiosin biosynthetic gene cluster comprises the nucleotide sequence of SEQ ID NO:1. A method for producing the prodigiosin comprises the steps of: producing a vector containing the prodigiosin biosynthetic gene cluster; transforming a cell with the vector; and culturing the transformed cell. The algicidal agent contains prodigiosin.
