MicroBlend - Bioaugmentation Product

A Blend of Vitamin B12 and Yeast Extract

MicroBlend is an easy to use vitamin B12 and yeast extract product containing over 55 mg/Kg of vitamin B12 and 37.5% yeast extract. MicroBlend stimulates microbial activity with micronutrients, vitamins and other cofactors that are not commonly found in simple substrates such as sodium lactate or emulsified vegetable oil. Adding MicroBlend stimulates rapid microbial growth of indigenous microbes at sites with micronutrient limitations. Sites utilizing bioaugmentation benefit from rapidly establishing a healthy population of the injected microbes.

Application

MicroBlend is mixed with an electron donor amendment and injected below the water table after dilution. Laboratory microcosm studies suggest concentrations of B12 of 0.025 mg/L provide the maximum stimulation of Dehaloccoicoides microbial growth. The dose response of yeast extract is less established but typical blends in Newman Zone ® emulsion would use 1.0% to 1.5% yeast extract on a dry weight basis.

Benefits – Easily Used in the Field

MicroBlend is an easy to blend liquid containing yeast extract and vitamin B12. A liquid nutrient formulation avoids the problems of dust and the difficulty of wetting a hydrophobic dry yeast extract powder.

Benefits – Pre-Measured Dosing

Each box of MicroBlend contains 1 gram of vitamin B12 and 15 pounds of dry yeast extract. Each box is divided into two 20 pound bags allowing the nutrients to be added in increments of 7.5 pounds of dry yeast extract and 0.5 gram increments of vitamin B12.
