Microbial screening test for lignite degradation. Quarterly progress report No. 3, July 1-September 30, 1985
Degradation of Beulah std No. 3 lignite was carried out by means of cupric oxidation, modified-autoclaved-cupric oxidation, sodium dichromate oxidation, and also by biological methods. Assessment of the yield of alkaline-soluble and methanol soluble products of both cupric oxidation and modified cupric oxidation (on a moisture-free and ash-free basis) was carried out by both ion chromatography and gel permeation chromatography. Fractionation of lignite for natural-uninoculated-biological growth resulted in no growth for both benzene-methanol fraction and alkaline filtrate fraction, whereas that of alkaline geletinous fraction resulted in positive growth of unidentified white-rot fungi. Acclimation of Polyporus versicolor to lignite was attempted. 10 refs.
