Nutrient Supplement

Under normal conditions there are sufficient nutrients to sustain microbial growth but when a release occurs, metabolism may be limited by the balance in electron donors and acceptors or the available nutrients.

Application Corner

Our approach to substrate dosing is based on site conditions. JRW Bioremediation L.L.C. provides substrates and nutrients for anaerobic bioremediation. The substrates provided include highly soluble materials such as WILCLEAR® sodium and potassium lactate, SoluLac® ethyl lactate, and Wilke Whey® whey powder and slowly soluble substrates including LactOil® soy micro-emulsion, and ChitoRem® chitin complex.

1. Fundamentals

Under normal conditions there are sufficient nutrients to sustain microbial growth but when a release occurs, metabolism may be limited by the balance in electron donors and acceptors or the available nutrients. This nutrient limitation may not be apparent once a substrate has been added to a system as degradation kinetics are significantly increased. In order to maximize degradation kinetics, the addition of a nutrient is prefered. In cases where a system is partially nutrient limited and there is excess substrate, the addition of a nutrient can not only increase kinetics but also increase substrate utilization efficiency as less of the substrate is used for non-degradation growth.

There are two types of nutrients supplements, those that provide growth factors and those that provide trace metals and minerals.

1.1 JRW’s Accelerite® bioremediation nutrient

JRW’s Accelerite® bioremediation nutrient is a specially formulated mix of growth factors that quickly stimulates anaerobic metabolism increasing both degradation kinetics and substrate utilization efficiency. Accelerite® can be added to any substrate to increase effectiveness.

Accelerite® Our Products
Field tests have shown that Accelerite® incresed overall microbial growth by over two orders of magnitude when used with emulsified vegetable oil or ethyl lactate within 12 days and within 22 days when used with whey powder. These systems rapidly began to become anaerobic quickly reaching sulfate reducing levels while reducing PCE almost 40% in 13 days and almost 90% in 82 days. Accelerite® has also been added to systems that showed a potential over application of substrate causing a drop in pH and very high TOC. Within 30 days of application, TCE began dropped from over 3 mg/L to less than 50 ug/L and the pH began to rise. After 90 days, and the TCE dropped to non-detectable levels and DCE dropped from over 13 mg/L to under 3 mg/L while VC dropped from over 23 mg/L to less than 5 mg/L.

1.2 JRW’s ChitoRem® Chitin

JRW’s ChitoRem® chitin complex contains about 1% nitrogen in a slow-release form that can help stimulate microbial growth. This can be important in poor soils or in situations where very high biomass is desired such as biochemical reactors.
