摘要：

Effective diffusion coefficients (Dag) of carbohydrates in modified κ-carrageenan gels, with and without Escherichia coli immobilized cells were determined. A diffusion cell based on the phenomena of sorption from a "well-stirred fluid" was used. Dag values were smaller in the gel with cells than without them. The effect of temperature on Dag was also studied. © 1990.
