Antimycotic Activity of Seaweed Extracts( Caulerpa lentillifera and Eucheuma cottonii) against Two Genera of Marine Oomycetes, Lagenidium spp. and Haliphthoros spp.
Biocontrol Sci 2019; 24(2):73-80BS

Abstract

Fungal infection mostly caused by marine oomycetes had hindered crustacean production thus searching for natural and safe treatment is currently needed. Thus, this study was conducted to investigate the antimycotic effect of different seaweed extract against marine oomycetes (Lagenidium spp. and Haliphthoros spp) . Two seaweeds species (Eucheuma cottonii and Caulerpa lentillifera) were extracted using ethanol, methanol and water. Each extracts was tested on four fungi strains of marine oomycetes species for minimum inhibitory concentration (MIC) and fungicidal activities. C. lentillifera ethanol extract showed the highest antifungal effect where it can inhibit three from four fungal strains. Meanwhile, E. cottonii ethanol extract has lowest MIC (500 ppm) and inhibit L. thermophilum IPMB 1401 and H. sabahensis IPMB 1402 hyphal growths. Antimycotic effect on zoospores production shows reduction in production after 12 h immersion for three marine oomycetes species. Seaweed extracts toxicity on Artemia sp. showed approximately 5% mortality at 12 h immersion. It is suggested that 12 h immersion of seaweed extract is a suitable treatment for marine oomycetes in aquaculture. This study does not only show potential alternative control method for crab larvae health management, it may also contribute to the sustainable development and food security of aquaculture industry.
