✦ Synopsis

Living Lactobacillus delbrueckii cells were entrapped in calcium alginate gel beads and employed both in recycle batch and continuous column reactors to produce l-lactic acid from glucose. The substrate contained 1% (w/v) yeast extract as nutrient and 4.8X (w/v> solid calcium carbonate as buffer. The maxiumum lactic acid yield obtained was 972, of which more than 90% was l-lactic acid. The biocatalyst activity half-life in continuous operation was about 100 d, and only about 10% of the activity was lost during intermittent storage of the bioreactor at +7'C for about 5 months.
