Monospecies Biofilms from a Crustose Coralline Alga Induce Settlement in the Reef-Building Coral Leptastrea purpurea

Associated bacteria were isolated from Hydrolithon reinboldii, a crustose coralline alga sampled in Luminao, Guam. Selected strains were grown as a monospecies biofilm and tested for their ability to induce settlement (attachment and metamorphosis) in larvae of the reef-buiding coral Leptastrea purpurea, which was sampled in Luminao, Guam as well
