Abstract
A method for reducing the size of coal particles includes the steps of inoculating a coal sample with an anaerobic bacteria or decarboxylating enzyme therefrom and incubating the inoculated sample. The microbes and/or decarboxylating enzymes biochemically modify the coal to reduce the size of the coal to ultra-fine particles. The biotreatment modifies the coal so as to improve its dispersibility in coal-water slurries.
