Abstract
Dioscorea deltoidea Wall (Dioscoreaceae) cell cultures were entrapped by passive invasion into reticulate polyurethane foam cubes. Immobilization of cells grown in medium containing 3% sucrose reduced the lag phase in growth and thereby reduced the time required to reach maximum diosgenin concentration by 36% compared to cells in suspension culture. Immobilization also increased the total diosgenin produced by 40%. Increased efficiency in diosgenin production was greatest in 3% sucrose; higher concentrations inhibited diosgenin production.
