Patent number: 10179355Abstract: A method for treating contaminated water or other contaminated media has been developed. Bioremediation enhancing agents (BEAs) such as yeast metabolites (YM) and other yeast derived products are used to facilitate microbial treatment of the contaminated material. Polysaccharides are also an effective BEA when used alone or in combination with the yeast derived products. The BEAs may work with microbes and electron donors to improve the rate of contaminant degradation and to increase the efficiency of electron donor utilization. A number of novel electron donors are also disclosed.Type: GrantFiled: May 5, 2017Date of Patent: January 15, 2019Assignee: JRW BIOREMEDIATION, LLCInventors: Donovan N. Smith, Michael R. Sieczkowski, Wayne H. Wilke

Patent number: 7959806Abstract: A new and improved method for treating mine influenced water (MIW) or other environmental contamination is disclosed. A number of electron donors are disclosed, including chitin complex-containing materials. The chitin complex-containing materials may modify the pH and reductive-oxidation potential of the contaminated media within the subsurface or within a treatment cell to facilitate metal removal through biological, chemical, and physical means, or a combination thereof. Bioremediation enhancing agents such as yeast products may also be used to facilitate microbial treatment of the contaminated sources. The yeast products may work with microbes to improve the rate of contaminant removal and promote microbial growth.Type: GrantFiled: April 28, 2008Date of Patent: June 14, 2011Assignees: JRW Bioremediation, LLC, The Penn State Research FoundationInventors: Michael R.

Publication number: 20040195176Abstract: A method for in situ bioremediation of contaminants in the environment is described. The method includes adding an electron donor to ground water in an amount sufficient for a microbe in the ground water to use the electron donor for reducing the contaminant into an innocuous derivative thereof. Illustratively, the electron donor contains about 0.1 to 75% by weight of chitin, such as crustacean shell, partially deproteinized crustacean shell, ground mushrooms, or a fungal fermentation broth. The chitinous electron donor can be added to the ground water as a particulate solid or aqueous slurry.Type: ApplicationFiled: April 7, 2003Publication date: October 7, 2004Applicants: SRP Technologies, Inc., JRW Bioremediation, LLCInventors: Kent S.

Publication number: 20040157317Abstract: Methods for enhancing bioremediation of ground water contaminated with nonaqueous halogenated solvents are disclosed. An illustrative method includes adding a composition to the ground water wherein the composition is an electron donor for microbe-mediated reductive dehalogenation of the halogenated solvents and enhances mass transfer of the halogenated solvents from residual source areas into the aqueous phase of the ground water. Illustrative compositions effective in these methods include surfactants such as C2-C4 carboxylic acids and hydroxy acids, salts thereof, esters of C2-C4 carboxylic acids and hydroxy acids, and mixtures thereof. Other illustrative compositions according to the present invention include oleyl lactylic acid and, optionally, oleic acid and lactic acid or salts thereof. Especially illustrative compositions for use in these methods include lactic acid, salts of lactic acid, such as sodium lactate, lactate esters, and mixtures thereof.Type: ApplicationFiled: August 20, 2003Publication date: August 12, 2004Applicants: SRP TECHNOLOGIES, INC., JRW BIOREMEDIATION, LLCInventors: Kent S.
