| Summary: | <p>Because of poor survival of probiotic bacteria, microencapsulation evolved from the immobilized cell culture technology used in the biotechnological industry. Two probiotic strains, <em>Bifidobacterium </em>(BB-12) and <em>Lactobacillus acidophilus </em>(LA-5) were immobilized in calcium alginate by extrusion method. Encapsulation parameters and efficacy of this method were evaluated. Growth factors of these two bacteria were also measured by culturing in 10-L fermenter. Growth curves were obtained with respect to optical density and dry biomass weight. Encapsulation yield was over than 60% in each experiment. Scanning electron microscopy (SEM) of Entrapment of cells in alginate matrix and cross-sections of dried bead were obtained and illustrated<em>. Bifidobacterium</em> have been shown better biotechnological properties.</p> |
