Aplikasi Mikrosimbions Spons Laut Sebagai Material Dalam Metode Bioremediasi Toksisitals Logam Berat

The marine environment is very vulnerable to being polluted by various types of heavy metals due to humanactivities. The purpose this research is to detoxify the toxicity of Lead, Mercury and Arsenic metals in bioremediation methods using sea sponge microsymbiont. The method of bioremediation of heavy metaltoxicity begins: isolation,culture of Hyrtios erectus sponge isolates, suspension preparations, 24-hour incubation. Heavy metal solution Pb, Hg, As concentrations of 100 ppm were interacted with sponge microsymbiont suspension with a volume ratio of 1: 1, within 1 to 15 days. The results of interaction are extracted, concentrated, acidified, concentration analysis using AAS. Measured absorption is extrapolated graph form of the regression equation. Maximum bioremediation results of heavy metals by PS
symbionate isolate PS1 strain SLG510A3-8 of Pb = 87.50%; Hg = 79.03% and As = 64.04%, while PS2 strain RCH2 isolate for Pb = 88.24%; Hg = 82.20%; As = 64.69%. It was concluded that PS2 strain RCH2 isolates tended to be stronger in bioremediating Pb, Hg and As heavy metals than PS1 strain SLG510A3-8 isolates.
