ABSTRACT
Microbially enhanced coalbed methane technology must be used to increase the methane content in mining and generate secondary biogenic gas. In this technology, the metabolic processes of methanogenic consortia are the basis for the production of biomethane from some of the organic compounds in coal. Thus, culture nutrition plays an important role in remediating the nutritional deficiency of a coal seam. To enhance the methane production rates for microorganism consortia, different types of nutrition solutions were examined in this study. Emulsion nutrition solutions containing a novel nutritional supplement, called dystrophy optional modification latex, increased the methane yield for methanogenic consortia. This new nutritional supplement can help methanogenic consortia form an enhanced anaerobic environment, optimize the microbial balance in the consortia, and improve the methane biosynthesis rate.

Mentions: Pure carbon dioxide, methane, and nitrogen were used to calibrate the sensor according to the manufacturer’s recommendations. Pure nitrogen was first used to initialize and create a baseline for both channels (methane and carbon dioxide). Pure methane was used to calibrate for 100% methane and 0% carbon dioxide. Pure carbon dioxide was used to calibrate for 100% carbon dioxide and 0% methane. Finally, pure nitrogen was used again to calibrate the zero level for both channels. Mixtures of 20% methane and 80% carbon dioxide, 50% methane and 50% carbon dioxide, and 80% methane and 20% carbon dioxide were used to test the sensor’s linear character. To obtain the best response time, the sensor was placed in the middle port of a three-neck flask (Fig 3).
