Abstract

Sea morphological sponge searches that potentially degrade contaminated wastes Poly Aromatic Hydrocarbons (PAH) are important to aim to identify earlier physical features of marine sponge types that potentially reduce the toxicity of PAH. Previous research has shown that a special type of marine sponge marker that may be symbiotic with microorganisms capable of producing enzymes for degradation of PAH, whose body structure contains mucus or its body is protected by a black layer such as mud embodied as mucus. Sponge identification method is done by noting the special sign (color, texture, shape, size and depth of sampling). Then sequentially the sponge morphology identification followed the guidebook. The results of the analysis of four types of sponges, found that the sponge Petrosia (Strongylophora) corticata (Sp 1) in the body there is mucus and Niphates sp (Sp 2) along the surface found a black layer of textured mucus. The structure indicates that the two potential sponges form a symbiont with certain types of bacteria that can destabilize the PAH benzene ring, so that the PAH toxicity level decreases. Hyrtios erectus (Sp3) and Clathria (Thalysias) reinwardti (Sp 4) sponges, both of which do not potentially contain bacterial symbionts that can reduce the toxicity of PAH.
