Biosolubilization of coal by Candida in glucose limited cultures
- Spelman College, Atlanta, GA (USA)
Coal biodegradation is attracting the attention of many workers because of its significance for efficient bioconversion of coal into useful chemicals. The authors work is based upon the beneficiation of a fungus (candida) on subbituminous coal. Candida was grown on both solid and liquid sabouraud medium and the coal solubilizing activity was studied at varying glucose concentration and temperature. Lower glucose concentration and higher temperature enhanced coal solubilizing activity by this fungus. Preliminary work has begun on analyzing organic extractions (alumina chromatography) of the liquid produced after microbial solubilization, including elemental analysis, solubility, molecular weights and chemical structure. This preliminary work suggests that the candida could metabolize naturally occurring coal as substrate.
