Production method of organic acid and high rank coal via biological low rank coal conversion

摘要

The present invention provides a simple and effective biological conversion method which can effectively operate even in the presence of moisture for efficient and clean utilization of high-water low-grade coal, operates under mild conditions, and produces a wide variety of highly utilizable products Preparing an Escherichia coli Echigonensis SLA4 strain isolated from soil or sludge; Culturing the Escherichia coli Echigonensis SLA4 strain in a high-grade coal of low grade; And the aspirant Echigonensis SLA4 strain decomposes the volatile components of the high-grade low-grade coal contained in the medium to produce an organic acid, and at the same time, the hydrophilic component contained in the high- And a method for producing organic acid and high-grade coal.
