Lactic Acid Bacteria (LAB) are a particularly interesting group of bacteria that are one of the key components of a full-blown KNF regime. Why are they particularly interesting, I hear you ask? Well, they are one of the few groups of bacteria that are capable of functioning in both aerobic and anaerobic conditions. “Anaerobic bacteria?” I hear you cry, “What the crikey-fuck do you want them for? That’s root disease territory isn’t it?” Well, yes, the majority of root diseases are anaerobic pathogens, but these bacteria are cut from an entirely different cloth, my friend.
