The present invention discloses compositions and methodologies for the utilization of probiotic organisms in therapeutic compositions. More specifically, the present invention relates to the utilization of one or more species or strains of lactic acid-producing bacteria, preferably strains of Bacillus coagulans, for the control of gastrointestinal tract pathogens, including antibiotic-resistant gastrointestinal tract pathogens, and their associated diseases by both a reduction in the rate of colonization and the severity of the deleterious physiological effects of the colonization of the antibiotic-resistant pathogen. In addition, the present invention relates to the utilization of therapeutic compounds comprised of lactic acid—producing bacteria and anti-microbial agents such as antibiotics, anti-fungal compounds, anti-yeast compounds, or anti-viral compounds. The present invention also discloses methodologies for: (i) the selective breeding and isolation of probiotic, lactic acid-producing bacterial strains which possess resistance or markedly decreased sensitivity to anti-microbial agents (e.g., antibiotics, anti-fungal agents, anti-yeast agents, and anti-viral agents); and (ii) treating or preventing bacteria-mediated infections of the gastrointestinal tract by use of the aforementioned probiotic bacterial strains with or without the concomitant administration of antibiotics. While the primary focus is on the treatment of gastrointestinal tract infections, the therapeutic compositions of the present invention may also be administered to buccal, vaginal, optic, and like physiological locations.

The present invention relates to a method for producing lactic acid bacteria of a high concentration continuously using a membrane bioreactor. Specifically, the present invention relates to a method for producing lactic acid bacteria of a high concentration in a membrane bioreactor that comprises the steps of cultivating lactic acid bacteria in a membrane bioreactor including a membrane for product separation and a medium supply apparatus; supplying culture media to the bioreactor through the medium supply apparatus; continuously separating and discharging culture filtrate through the membrane for product separation; and recycling lactic acid bacteria continuously to the bioreactor. Additionally, the present invention relates to a method for producing lactic acid bacteria powder by freeze drying the bacteria produced in the membrane bioreactor using a freeze drying preservative composition. The lactic acid bacteria obtained through the membrane bioreactor is obtained in pellet form with a centrifugal separator, and is subjected to freeze-drying using the composition for freeze drying preservative containing certain amounts of trehalose, maltodextrin, starch and sodium carboxy methyl cellulose to form lactic acid powder. The lactic acid bacteria that have been converted into powder by such method exhibit superior stability chemically and physically compared to lactic acid bacteria powder that has been subjected to simple freeze drying.
