Can probiotics really survive up to a minimum of 2 years at Room Temperature?

Figure 1. Stability study of P. acidilactici stored at 4° C refrigerator and room temperature. The results were collected from an average of three different plates from three separate experiments. [In the graph - Blue: Capsules stored at 4° C; Red: Capsules stored at Room Temperature]

All of Imagilin's probiotics, which are made of Pediococcus acidilactici, do not require rigid storage conditions, and are capable of maintaining their survivability for longer periods of time up to a  minimum of two years. 

Product survivability can be established by a study as shown above to determine the stability of Pediococcus acidilactici stored at 4° C and also at room temperature. P.acidilactici is widely applied to farm and companion animals as feed additives, and is recognized as Generally Recognized As Safe (GRAS) by the United States FDA. Unlike other lactic acid bacteria, P.acidilactici is less sensitive to oxygen exposure and heat. Typically, a visible size colony can be obtained by overnight culture at 37° C even under aerobic cultivation. 

Freeze-dried P.acidilactici cultures encapsulated in a gelatin capsule can maintain viability up to two years either when stored at room temperature or at 4° C (figure 1). P.acidilactici survived even after 1-week incubation at 65° C. All these make P.acidilactici  the choice of probiotics to use against infectious diseases without the hassles of storage and concerns about viability over extended periods of time.
