It is a partially purified extracellular protein metabolite from the culture supernatant of probiotic strain, B. coagulans MTCC 5856 (LactoSpore®). It appears pale yellow to a brown colored liquid that is completely soluble in water.

It belongs to a class of bacteriocin proteins, which are produced by one strain of bacteria and act against other pathological organisms (Riazi et al., 2012).
