Furthermore, compared to other immobilization methods, Ca-alginate immobi-lization seems to be more effective for reducing the inhibitory effect of metal ions or impurities on cell growth.
In this work , the utilization of high solid paper sludge inimmobilized cells of Z. mobilis was studied. In addition, pro-cess enhancement was investigated by using immobilized cells in
repeated batch fermentation to increase ethanol production.the production of ethanol using the SSF process by Ca-alginate
