Development of Optimal Bio-encapsulated Media for Organic/Inorganic Odor Reduction

【A bio-encapsuled media was developed to apply on reducing odors produced from organic waste treatment process. The microorganism, candida tropicalis, was encapsulated in sponge media consisted of polyurethane material. Sodium alginate as a natural polymer which does not affect to hydrophilic microbes and PEGDA(poly ethylene glycol diacrylate) as a artificial polymer were used for the encapsuled media. The media was evaluated with TMEDA (N,N,N',N'-tetramethylethylenediamine, 0.02~0.1%) as a catalyst at different temperature 25 and $35^{\circ}C$ . The best performance was achieved with 0.02% of TMEDA at $25^{\circ}C$ . The microbes' activity in the media was examined by Live/Dead cell method.】
