| Number | Title | Issue Date |
| 7966767 | Enhanced plant growth using alkane biostimulation A method of enhancing plant growth comprises the step of introducing an alkane into a location adjacent to a plant. The alkane can be introduced intermittently, and can be combined with another gas and/or nutrients. The alkane preferably comprises a butane substrate... | 06/28/2011 |
| 7550085 | Bioventing remediation method Bioventing methods create a bacterial treatment zone at a contaminated site by supplying a hydrocarbon food source to the treatment zone, and recirculating the hydrocarbon to the treatment zone. The inventing methods may inject, circulate, extract and reinject hydro... | 06/23/2009 |
| 7329532 | Remediation of sulfur-containing pollutants with hydrocarbon-utilizing bacteria Methods and apparatus are disclosed for remediating sulfur-containing pollutants with a hydrocarbon that is used to stimulate the growth of hydrocarbon-utilizing bacteria. The hydrocarbon is preferably an alkane such as butane. The sulfur-containing pollutant may co... | 02/12/2008 |
| 7314548 | Bioventing remediation system Bioventing systems create a bacterial treatment zone at a contaminated site by supplying a hydrocarbon food source to the treatment zone, and recirculating the hydrocarbon to the treatment zone. The bioventing systems may inject, circulate, extract and reinject hydr... | 01/01/2008 |
| 7192523 | Methods for treating agricultural waste and producing plant growth-enhancing material Methods and apparatus are provided for treating agricultural waste with an alkane substrate to stimulate bacterial digestion. The alkane treatment may also reduce odor of the agricultural waste material. The agricultural waste may include animal waste, vegetable mat... | 03/20/2007 |
| 7182871 | Wastewater treatment with alkanes An apparatus and method are provided for treating wastewater with alkanes such as butane. An oxygen-containing gas may also be introduced into the wastewater. Butane, because of its relatively high solubility, rapidly dissolves in the wastewater, thereby significant... | 02/27/2007 |
| 6923914 | Remediation of metal contaminants with hydrocarbon-utilizing bacteria Methods and apparatus are disclosed for remediating metal contaminants using hydrocarbons which stimulate the growth of hydrocarbon-utilizing bacteria. The metal contaminants may include heavy metals such as arsenic, antimony, beryllium, cadmium, chromium, copper, l... | 08/02/2005 |
| 6835312 | Method and apparatus for treatment of septic systems with alkane-utilizing bacteria Septic systems are treated with alkane-utilizing bacteria. Alkanes such as butane are injected into septic system wastewater in order to enhance growth of alkane-utilizing bacteria which degrade wastes. Aerobic processes may be achieved by injecting an oxygen-contai... | 12/28/2004 |
