The bacteria on Bio-STAR products allow to increase the natural process of organic matter transformation. These selectively adapted bacteria oxidize malodorous compounds, and have a greater ability to contend with intestinal reducing bacteria by reason of their superior digestive capabilities. The quick bio-enzymatic action prevents the reaction of certain compounds by acting directly on the complexes that cause bad odors. Thus with the regular use of Bio-STAR, odors associated with fermentation can be reduced, creating a safer working and breeding environment.
