Abstract: Five strains of probiotic bacteria were fiber embeded and cultured in a continuous fibrous bed bioreactor with corn fiber as the carrier.The immobilized biomass was studied by selective culture methods.Bifidobacterium longum TQ21-2-2,Lactobacillus acidophile CICC06005,Clostridum butyric TO-A,Bacillus mesentericus TO-A and Enterococcus faecalis T-110 were found to have coexisted stably.The total biomass of five probiotics in immobilized phase was 3.5×1010 g in corn fiber of the fibrous bed bioreactor.The system can be used to obtain formulation of microecological and fiber embeded tablets,so as to produce solid high biomass commensal probiotics products continuously.The fiber and bacteria were dried into functional food tablets with probiotics biomass in the amount of 109/g,1000 times higher than that estimated in China national standard.
