Decomposition of natural rubber serum was investigated by using two kinds of microorganisms, namely, lactic acid producing bacteria and green algae, and four kinds of methods for immobilizing the microorganisms, which were adsorption on a resin, cross-linking, microcupsulation, and adsorption on glass-beads. The immobilized bacteria in microcapsule resin gave high ability to produce lactic acid and to consume rubber waste. This type of immobilized bacteria also exhibited high ability when it was applied to decompose rubber waste by using middle-scale reactor.
