Abstract

Biological processing of coal at mild operating conditions could provide significant economic and environmental advantages over thermal/chemical coal conversion processes. Thermophilic micro-organisms with the ability to biosolubilize Leonardite were isolated from geothermal waters. Biosolubilization correlated with final culture pH. The mechanism of solubilization was a microbially-produced alkaline compound. Metal ion sequestering agents (chelators) contributed to biosolubilization.
