Blis have bought two products to market so far...K12 and M18. They have another product up their sleeves which has been mentioned a few times over the years. It is Q24 or Micrococcus Luteus. Until Blis has more resources available to it little progress will be made in bringing it to market but it is worth remembering it exists and pondering its potential. Several patents exist which give good insight into its potential. This one is well worth a read, and is largely very readable to the non scientists among us:
