Quantitative PCR reveals transient and persistent algal viruses in Lake Ontario, Canada.

abstract：:Since Robert Koch and colleagues found agar to be an effective gelling agent over a century ago, the pure culture method using agar plates has long been a standard of microbiology. Agar is undoubtedly easy to handle and useful for culture of microorganisms, but recent discovery of the ubiquity of microorganisms that c...
