Bacteria and diatoms are primary colonizers of marine surfaces and hence play a crucial role in the attachment and subsequent growth of macro-organisms. It has been suggested that the temperate green alga Ulva lactuca relies on the defence provided by the epiphytic bacterial community to regulate surface fouling of colonising organisms. In this study, ten resident bacterial isolates from tropical U. lactuca were tested for their antibacterial and antidiatom properties that may regulate surface colonization on the algae. Sixty percent of the epiphytic isolates expressed antibacterial properties against other resident bacteria and 80% had antidiatom activity against the pennate diatom, Cylindrotheca fusiformis. Isolates of the Pseudoalteromonas genus showed both- antibacterial and antidiatom activities, while members of the genus Bacillus, Vibrio and Shewanella mostly possessed antidiatom activity. Our results show that a high proportion of bacterial isolates from tropical U. lactuca, like that of their temperate counterparts contain antibiotic properties that might impact on the bacterial community composition and prevent fouling by diatoms.
