microencapsulation and fermentation of lactobacillus acidophilus la-5 and bifidobacterium bb-12
نویسندگان
چکیده
because of poor survival of probiotic bacteria, microencapsulation evolved from the immobilized cell culture technology used in the biotechnological industry. two probiotic strains, bifidobacterium (bb-12) and lactobacillus acidophilus (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 . bifidobacterium have been shown better biotechnological properties.

BACKGROUND There are some evidences for the immunomodulation disorders in the response to intestinal microbiota in inflammatory bowel disease. Yogurt is a fermented milk product made with a starter culture consisting of different probiotics which could be colonized in intestine. However, the role of probiotics in the aetiopathogenesis of ulcerative colitis (UC) has not been clarified. To determ...

In the present study, the cells of Bifidobacterium animalis subsp. lactis (BI-01) and Lactobacillus acidophilus (LAC-04) were encapsulated in cocoa butter using spray-chilling technology. Survival assays were conducted to evaluate the resistance of the probiotics to the spray-chilling process, their resistance to the simulated gastric and intestinal fluids (SGF and SIF), and their stability dur...
