Abstract

The PROBIOTIC, Lactobacillus acidophilus PTCC 1643 was encapsulated in CALCIUM ALGINATE beads with the objective of enhancing survival during exposure to the adverse conditions of the gastro-intestinal tract. The probitic was incubated in simulated gastro-intestinal conditions for 0, 30, 60, 90 and 120 min. at 37oC. The survivability of the PROBIOTIC, L. ACIDOPHILUS PTCC 1643 was expressed as the destructive value (D-value). Particle size distribution was measured using laser diffraction technique. Bead appearance was observed by scanning electron microscopy (SEM). The alginate coat prevented acid-induced reduction of the PROBIOTIC in simulated gastric juice (pH 1.5, 2 h), resulting in significantly (P<0.05) higher numbers of survivors due to retarding the permeation of the gastric fluid into the cells. After sequential incubation in simulated gastric (60 min) and intestinal juices (pH 7.25, 2 h), number of surviving cells were 6.5 log cfu ml-1 for encapsulated L. ACIDOPHILUS while 2.3 log cfu ml-1 was obtained for free cells.
