Description
Summary:Sponge is often used as a bio indicator and bio monitoring in determining the level of heavy metal contamination in the sea. The purpose of this research is to analyze the destruction of PAHs and the reduction of heavy metal toxicity. Biodegradation and bio-adsorption occur with a 30-day interaction between bacterial symbiont sponge suspension against modified liquid waste containing a mixture of PAHs (naphthalene) contaminants, heavy metals Cr (VI) and Cd (II). The period of interaction of bacteria with heavy metals for 15 days, bio-adsorption power was determined using AAS, while the interaction with PAHs, the level of biodegradation was measured using GC-MS and Infrared Spectrophotometer. The results achieved bacteria BP and PS, have biodegradation and bio-adsorption activities against extreme waste contaminated with a mixture of naphthalene and heavy metal. The level of biodegradation of BP bacteria to naphthalene is weaker than PS bacteria. The bio-adsorption power of PS bacteria is higher for Cr (VI) and Cd (II) ions. The components of naphthalene in extreme waste inhibit the bio-adsorption performance of BP and PS bacterial, conversely there is an effect of inhibition of bacterial activity on the biodegradation process of naphthalene by the presence of heavy metals.
