Variants reduce larval settlement and metamorphosis of M. coruscus. a The inducing activities of biofilms of two variant strains and the wild-type strain on larval settlement and metamorphosis with different initial CFU, respectively. b Cell densities of the attached biofilms formed by the two variant strains and the wild-type strain on glass slips with different initial CFU, respectively. Letters in A and B indicate a significance level of p < 0.05 in the same initial CFU
