The RCC now incorporates viruses

The Roscoff Culture Collection has just integrated 159 strains of viruses that have been isolated from water off Roscoff during project PICOVIR (ANR 07-Blan-0210) and contaminate the Mamiellophyceae Micromonas and Bathycoccus.

The shortlist of viruses is available here.
