Abstract :

Field experiments usually give ecologically relevant results contributing to understand the ecosystem deeply. In marine research, aquacultures are one of the most popular procedures used to carry out field experiments (figure a). In this study, the aquaculture of the green macroalga Ulva mutabilis was inoculated for the first time with freshly induced gametes (7-day old germlings) to culture large volume (200 L) with small axenic gametes. Two sets of aquaculture: defined community (inoculated with axenic gametes of U. mutabilis and two associated bacteria: Roseovarius sp. strain MS2. and Maribacter sp. strain MS6), and undefined community (inoculated of U. mutabilis axenic gametes only). In defined community U. mutabilis showed a healthy growth and development (figure b) whereas in undefined community U. mutabilis lost its ability for growing and developing and formed only callus-like colonies (figure c). Multivariate statistics of the GC/MS and LC/MS analyses along with acquisition of biological metadata revealed that the waterborne metabolites in defined community were affected qualitatively and quantitatively by the growth phases of U. mutabilis as was proven in previous study of bioreactor cultures (figure d, e).
