Abstract:

It is urgent to find effective and environmentally friendly antifoulants for marine industries. Marine derived microbial secondary metabolites are promising potential sources of nontoxic antifouling agents. Over the past seven years, we have focused on the investigation of antifouling potentials of fungal isolates from deep sea sediments and coral samples of the South China Sea and have obtained over 40 antifouling compounds from marine-derived fungi. These compounds mainly included alkaloids, butyrolactones, polyketides and fatty acids. The antifouling activity was primarily evaluated by antibacterial activity against larval settlement inducing bacteria and antilarval activity against larval settlement of bryozoan Bugula neritina and Balanus amphitrite and then tested in field trial. Four of the antifouling natural products showed significant antifouling activity in field trial in different seasons. The potentials of these antifouling natural products as non-toxic antifouling agents are under further evaluation.
