Biological processing has received considerable attention in recent years as a technology for the utilization of low-ranked coals. Several fungi and actinomycetes have been shown to liquefy highly oxidized coal in pure culture under aerobic conditions. This report describes the optimization of cultural conditions for coal solubilization by Candida sp. ML13, an organism originally isolated from a naturally weathered coal seam. Coal solubilization by surface cultures of Candida sp. has previously been demonstrated. The author describes here the elicitation of the activity in submerged cultures as well as the effect of carbohydrate concentration, carbon source, temperature, and agitation rate on coal solubilization by this organism.
