ABSTRACT
Spreaded and immobilized the bacterial cells entraped in PVA on pieces of cotton cloth as porous carrier. The conditions for preparing immobilized cells were as below cell concentration, 20 mg wet weight/ml; PVA concentration, 5%; spreading amount, 0.3ml/cm~2; immobilization for 12 hours in saturated boron acid solution. Then activated the immobilized cells in buffer containing dyes. Thus, immobilized cells with high decolorizing activity were obtained.In columns packed with immobilized cells, the decolorization efficiencies of continuous influent and intermissional influent were compared with each other. In twenty days, the decolorization rates were both higher than 90%; then the decolorization rate of continuous influent decreased to about 60% after 60 days while it still reached 80% in case of intermissional influent. The efficiency of the later was distinct higher than that of the former.
