Abstract: | Summary Characterization of lignocellulosic wastes from three paper mills in New York State indicated that a kraft mill sludge contained substantial quantities of utilizable cellulose and hemicellulose. This residue was tested as a carbon source for seven cellulolytic fungi.Trichoderma reesei DAOM 167654 accumulated a product of over 22% crude protein, and caused a conversion of sludge to protein of almost 15% in 3 days growth in shake flasks.T. reesei also produced the highest levels of cellulase, whileT. longibrachiatum produced more xylanase (35 units/ml) than other fungi examined. |
