METHOD OF OBTAINING CELLULASE DEFICIENT STRAINS OF WHITE-ROT FUNGI |
摘要 |
A method of obtaining cellulase deficient strains which have great ability to degrade lignin at the same time. The method comprises crossing a homokaryotic cellulase deficient mutant of a white-rot fungus having a full sexual cycle with a homokaryotic strain of the same fungus, this strain having great lignin degrading ability. Strains are subsequently selected that have great ligning degrading ability in combination with cellulase deficiency. A suitable white-rot fungis is Phanerochaete chrysosporium. The crossings are suitably performed for a plurality of generations. The strain of white-rot fungus obtained is used for delignifying lignocellulosic material. |
