<p>PURPOSE:To convert a substance having toxicity such as carcinogenicity and causing the problem of environmental pollution into a substance having low toxicity using an enzymatic reaction in high efficiency by using an immobilized biocatalyst produced by immobilizing Pseudomonas cepacia on a carrier. CONSTITUTION:The objective immobilized biocatalyst is produced by immobilizing Pseudomonas cepacia on a carrier. A polyacrylamide or carageenan can be used as the carrier. Toxic substances can be decomposed, converted and eliminated by contacting with the above immobilized biocatalyst at 0-40 deg.C. The toxic substances eliminable with the immobilized biocatalyst are phenolic compounds, carcinogenic substances (e.g. phenacetin or a alpha-naphthylamine), stenchful substances (e.g. indole or skatole), etc.</p> |
