โœฆ Synopsis

The photosynthetic bacteria Rhodopseudomonas capsulata strain BlO were immobilized in agar or in carrageenan beads ($ = 1-3 mm). Beads containing 5.8 mg cell dry weight/ml of gel produced hydrogen from lactate at a rate of 54 mL/h.g dry weight ; the efficiency of H2 production by immobilized cells was comparable to that of free cells and was 60 to 65% that of the theoretical maximum from lactate. Carrageenan-entrapped cells produced H2 steadily over a 1%day period.

This work examines the influence of various process parameters on papain entrapped in cross-linked kappa-carrageenan beads for improvement of its stability. A Doehlert shell design (DSD) was employed to investigate the effect of three process variables, namely kappa-carrageenan concentration, KCl co
