A particulate material, as well as a method of manufacturing and using the material, for promoting growth of petroleum degrading bacteria to aid in bioremediation of oil spills on water and in wetlands which consists of a core of microbial available nutrients having a coating, comprised of oleic acid and either stearic acid, palmitic acid, or a mixture thereof, which is lipophilic, and
This chapter reviews the application of additives used in bioremediation of chlorinated solvents and fuels for groundwater and soil remediation. Soluble carbon substrates are applicable to most site conditions except aquifers with very high or very low groundwater flow. Slow-release and solid substrates are intended to be long-lasting in supplying carbon for microbial growth thereby minimizing Hydrogen peroxide production is a well-known trait of many bacterial species associated with the human body. In the presence of oxygen, the probiotic lactic acid bacterium Lactobacillus johnsonii NCC excretes up to 1 mM H2O2, inducing growth stagnation and cell death. Disruption of genes commonly assumed to be involved in H2O2 production (e.g., pyruvate oxidase, NADH oxidase, and lactate
Hydrogen peroxide was used as the oxygen source at a concentration of g/L nutrient solution. The flask was then placed in the shake oven at rpm and 32° C. At the end of each week, one flask was removed and dried for analysis. Five mL of the mineral salt solution was added to the remaining flasks. This was repeated for eight Bioremediation uses microorganisms to degrade chemicals of interest and can be limited by mineral nutrients and terminal electron acceptors, especially oxygen. This research investigated in situ bioremediation with hydrogen peroxide (H[sub 2]O[sub 2]) as a supplemental oxygen source, added in increasing concentration, and addressed the

Environmental Protection Agency,  (OCoLC) Material Type: Government publication, National government publication, Internet resource Hydrogen peroxide, which is commonly used as an oxygen source for in situ biodegradation, tends to decompose into water and oxygen gas.
The rate of this decomposition relative to the oxygen demand of the contaminated aquifer is important to the success of an in situ process.
The objective of this study, which was performed at Eglin Air Force Base in northwest Florida, was to evaluate in situ Enhanced bioremediation utilizing hydrogen peroxide as a supplemental source of oxygen: a laboratory and field study.

A full-scale field demonstration on the use of hydrogen peroxide for in situ bioremediation of an aviation gasoline contaminated :// The hydrogen peroxide-amended groundwater is pumped into infiltration galleries or injection wells located in or near suspected source areas.
Generally, the infiltration/injection and groundwater extraction scheme is designed to promote the circulation and distribution of hydrogen peroxide and dissolved oxygen through the treatment area (EPA ). Bioventing combines the capabilities of soil venting and enhanced bioremediation to cost-effectively remove light and middle distillate hydrocarbons from vadose zone soils and the groundwater table.
Soil venting removes the more volatile fuel components from unsaturated soil and promotes aerobic biodegradation by driving large volumes of air into the :// Enhanced bioremediation is an efficient technology when compared to alternative technologies. The two major advantages are lower capital cost and the ability to perform the task insitu.
