Bacteria are found everywhere. They can safely and efficiently digest waste. Give them water and food and they will multiply quickly. Some bacteria require oxygen (aerobic) to function and some will function only in the absence of oxygen (anaerobic). Facultative bacteria can function under both conditions. A consortium of different strains and types of bacteria are carefully chosen and blended to act in harmony with great efficiency, like a classical orchestra. Biomaster products contain a mix (consortium) of aerobic, anaerobic and facultative bacteria.
