Effects of ocean acidification on the growth and biochemical composition of a green alga (Ulva fasciata) and its associated microbiota
In marine ecosystems, fluctuations in surface-seawater carbon dioxide (CO2), significantly influence the whole metabolism of marine algae, especially during the early stages of macroalgal development. In this study, the response of the green alga Ulva fasciata for elevating ocean acidification was i...
