Why does the MICROBE-LIFT/PL smell like rotten eggs?
The smell is attributable to the natural production of hydrogen sulfide by sulfate reducing bacteria as part of the ecosystem. This provides a source of energy for the purple sulfur bacteria in the product and as a metabolic inhibitor, preserves the product, giving it its long shelf life while in the container. If I open it and there’s no smell, how do I know if it’s still good? If it is pinkish or brownish in color, it should be alright. It is definitely bad if it is whitish-grey and has a burnt rubber smell. The bacteria are definitely dead in that case. Is there a listing of expiration dates on products? No, we do not list expiration dates on the products. There is a batch number on each that can be traced when necessary.
