-Acyl Homoserine Lactone Production by the Marine Isolate, .

(isolate SD1D, with 98.5% sequence similarity to DMS 21967 KOPRI 20902) is a marine bacterium that was isolated from ballast tank fluids as part of a biofilm study in 2014. Our previous work indicated that although this strain produced no detectable biofilm, it was the only isolate to produce -acyl homoserine lactones (AHLs) in assays using the broad-range reporter strain, KYC55.
