A selective Lignin degrading fungus belongs to
Answer: C
White-rot fungi, for example Phanerochaete chrysosporium, degrade lignin selectively and leave the whitish cellulose behind, so a selective lignin degrader belongs to the white-rot group. Brown-rot fungi attack cellulose and hemicellulose and leave the brown lignin, and soft-rot fungi break down cellulose in very wet wood. Red-rot is not a standard category of wood-decay fungi, so it is wrong. The lignin is broken down by enzymes such as lignin peroxidase and manganese peroxidase, which is the reason that these fungi are studied for biopulping and for degrading pollutants.
