Embodiment

[0088] Bench Test of Effectiveness of "Methane Inhibitor RYR"

[0089] Purpose

[0090] The purpose of the laboratory study was to evaluate the effectiveness of the methane inhibitor RYR (MIRYR), a composition of the invention developed by the inventors herein. The product is designed to inhibit methane production in environments where methanogens are established and active.

[0091] Materials and methods

[0092] Two anaerobic reactors were utilized, a control reactor and a test reactor. Both reactors were inoculated with expired dietary supplement treated with biomass containing active methanogenic populations. The reactor was fed weekly and operated as an anaerobic sequencing batch reactor as described by Cassidy et al. (2008a, 2008b), which is incorporated herein by reference. [CassidyDP, HirlPJ, BeliaE.(2008a). Methane production from methanol co-products inanaerobicsequencingbatchreactors in anaerobic sequencing batch reactors, WaterScience&Technology.58(4): 789-...

Abstract

This method of restricting methane production in methanogenic bacteria, by the use of the enzyme and coenzyme inhibitors, works during anaerobic reductive dechlorination. Various compounds such as, but not limited to, red yeast rice, vitamin B10 derivatives, and ethanesulfonates are utilized to disrupt these different enzyme and coenzyme systems responsible for the production of methane. This method affects the competition of the methanogen and halo bacteria for the organic hydrogen donors that are injected in the soil and groundwater system during the remediation process.

Description

[0001] Cross References to Related Patent Applications [0002] This patent application is entitled "Inhibition of Methane Production During Anaerobic Reductive Dechlorination" and is a continuation-in-part of co-pending patent application number 13 / 785,840 filed March 5, 2013 by the same inventor application, hereby claiming priority to that patent application Ser. No. 13 / 785,840. technical field [0003] The present invention involves the use of various inhibitors of the different enzyme and coenzyme systems responsible for methane production. The present invention utilizes red yeast rice, vitamin B10 derivatives, and ethanesulfonate to disrupt enzyme and coenzyme systems and limit the methane production rate of methanogens. Background technique [0004] Halogenated volatile organic compounds (VOCs), including chlorinated aliphatic hydrocarbons (CAHs), are the most commonly occurring pollutant types in soil and groundwater at Superfund sites and other hazardous waste sit...
