  • a Environmental isolates were named using the best BLAST (1) hit for the partial 16S rRNA gene.

  • b +, a PCR band of the correct size was amplified; −, two or more PCRs failed to amplify a band of the correct size.

  • c +, an optical density at 600 nm of >0.1 was reached by day 30; −, no observable growth on the chitin substrate.

  • d Type strains used to assay chitin growth and amplify chitinase A sequences were obtained from ATCC (American Type Culture Collection), JM (laboratory of John Mekalanos, Harvard Medical School), JP (laboratory of Jarone Pinhassi, Kalmar University), or KB (laboratory of Kathy Boetcher, University of Maine). Environmental isolates were obtained from a previous study (41), and new strains were isolated from the IBYC (Ipswich Bay Yacht Club, Ipswich, MA) and OP (Oyster Pond, Falmouth, MA) as described previously (41).
