Tri-Phasic 12 is a proprietary blend of vitamins, minerals and organic nutrients used to stimulate microbial activity in product applications for Micro-Bac International, Inc.® biological products where indigenous nutrients are insufficient to support optimal microbial activity. Such applications include bioremediation of contaminated soil and water. Tri-Phasic 12 may also be used in the remediation of oligotrophic waters and tank bottoms. By lowering the carbon/nitrogen ratio, biodegradation is enhanced and mineralization is promoted. Tri-Phasic 12 is supplied in an easy-to-use colloidal liquid form that flows and is freely soluble in water. It is designed to be used in conjunction with Micro-Bac International, Inc.®  products such as M-1000®H.

Tri-Phasic 12 contains all the major and minor mineral compounds as well as defined vitamins required by the specific microorganisms used in the Micro-Bac International, Inc.® products. It supports maximal activity of these microorganisms under both aerobic and anaerobic conditions.
