Abstract: Abstract:Thraustochytrids are fungal protists, commonly found in fallen leaves and sediment in mangrove environment. Mangrove sediment, being the sink of pollutants, coming from fresh water runoff, contains high concentrations of heavy metals. In Taiwan, heavy metal ions including Cu2+ , Zn2+, Cd2+, Ni2+,Pd2+,Sn2+ , Hg2+,Mn2+ and As2+ are commonly detected in the water. In this study, the effects of Cu2+ and Zn2+ on the growth of a Schizochytrium sp. IMB0056 isolated from fallen mangrove leaves at the river mouth of Erjen River, Taiwan are investigated. Schizochytrium sp. IMB0056 was grown in a liquid medium(Peptone, yeast extract and glucose.) supplement with 0.1, 0.2, 0.4 and 0.8 ppm Cu2+ ions. Preliminary results suggested that the growth of Schizochyrium sp. IMB0056 was not effected by the increase of concentration of Cu2+ ion. Cu2+ ions, being an essential nutrient, for the growth of thraustochytrids, at low concentration may, in fact, stimulate the growth of Schizochytrium sp. IMB0056. Experiments on Zn2+ ion is in progress and results will be presented in the conference.
