Genotypic diversity, biofilm capacity and in vitro antagonistic activity of fluorescent Pseudomonas isolates from Ephydatia fluviatilis.

1SE, SF, SG, SH – Ephydatia fluviatilis individuals collected in 2008.2N - total number of isolates per sponge sample.3H' - BOX-PCR-based (Fig. 2) genotypic diversity of fluorescent Pseudomonas per sponge sample, estimated with the Shannon diversity index.4All other values refer to the number of isolates from each sponge individual tested positive for biofilm formation (Biofilm), antagonism towards Rhizoctonia solanii AG3 (R. sol.), Pythium ultimum 67-1 (P. ult.), Fusarium moniliforme CBS 218.76 (F. mon.) and Bacillus subtilis F6 Rpr (B. sub.), and predation resistance towards Colpoda steinii Sp1 (C. stein.).
