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: Nutrition solution #1 was a standard nutrition that used as a control culture medium which did not contain the DOL emulsion. The experimental results indicated that a minimum incubation time was required for the initial methanogenic consortium culture (Fig 4). As the culture developed, the methane concentration increased. However, the methane production rate of the methanogens was not ideal under these conditions because it was based on the hydrolytic and fermentative bacterial degradation of the organic matter in the coal [16–18].
