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: The coal samples were sealed under nitrogen in sterile stainless steel jars (manufactured by Thermo Scientific Oxoid). The coal was safeguarded with nitrogen during sieve classification. A 2,000 g 10-to-15 mm-diameter fraction was collected and sealed in sterile wide-mouth polypropylene jars (manufactured by Thermo Scientific Oxoid) with nitrogen protection and stored at 4°C. Formation water samples of 5,000 mL were stored in sterile barotropic anaerobic jars (manufactured by Thermo Scientific Oxoid) (Fig 2) at 4°C. Nitrogen was used to increase the gas pressure at the top of the jar when extracting the formation water for sampling. In this manner, the groundwater was maintained under anaerobic and aseptic conditions.
