摘要：

Microcapsules prepared from sodium cellulose sulfate and poly(dimethyldiallylammonium chloride) have been shown to be well suited for encapsulation of biological objects. The citrate-accumulating yeast Yarrowia lipolytica was immobilized using this method without severe lass of vitality and catalytic activity. The encapsulated cells had an average productivity of 0.125gl(-1) h(-1). The yield was 0.45g acid g(-1) glucose. I;he immobilized biocatalyst lost the catalytic activity, but was still able to divide after 2,000 h use.
