摘要：Immobilization of growing bacterial cells was considered as aninnovative technique and very effective in dealing with majorenvironmental challenges for bioremediation of organics-loadedwastewater. This study was undertaken to investigate the aerobicbiodegradation of furfural in aqueous solution by usingimmobilized Bacillus cells in spouted bed bioreactor. Bacilluscells were individually immobilized in the matrices of sodiumalginate, guar-gum, and agar-agar; each was cross linked inpolyvinyl alcohol. Immobilized cells exhibited efficient furfuraldegradation in several successive reuse batches up to 3 cycleswithout losing their degradation activity which could provideeconomic advantages when used in industrial-scale applications.Results of batch experiments in fluidized spouted bed bioreactordemonstrated that complete removal of furfural usingimmobilized Bacillus cells in the first and second cycles wasachieved after 450 and 480 min, respectively. The removalefficiency of furfural was 100%, 100%, and 95% for the 1st,2nd, and 3rd, cycles, respectively. Unlike the free cells, thepotentiality of the immobilized cells is that they could be reusedwithout reduction in their ability to degrade hazardous furfural.Additional advantage of immobilized cells compared to freecells, is their ability to tolerate high concentrations of furfural.
