Cells on fibers to degrade PAH and upgrade coal
There are over 2000 sites contaminated with PAH`s from coal burning plants. White rot fungus degrades phenanthrene and anthracene, but the fungus needs air to grow. When grown on old cardboard boxes and buried, air is entrapped in the corrugations for growth of the fungus. When holes are put in the valleys of the corrugations and rotated in a half full reactor, drops are formed. Mass transfer to drops is much faster than to a flat surface, as described in Patent 5,256,570, so the fungus grows faster. Low rank coal can be upgraded to more valuable products with the fungus, say some Australians, but the problem is supplying oxygen. Celite can be entrapped in the fibers to ferment coal derived synthesis gas. The paper describes these processes.
