TLDR
Phellinus pini-2, Pholiota mutabilis, Phlebia brevispora-l and Phanerochaete chrysosporium were the best delignifiers of both birch and pine.Abstract:
Thirty wood-inhabiting basidiomycetes were screened for their ability to selectively delignify wood, The amount of lignin and carbohydrates removed and the mo hological and ultrastructural characteristics of the decayed wood were the major criteria used to determine fungi with superior lignin-degrading ability. Phellinus pini-2, Pholiota mutabilis, Phlebia brevispora-l and Phanerochaete chrysosporium were the best delignifiers of both birch and pine. Different isolates of the same species of fungi differed in both the type of decay caused and their selectivity for lignin. Almost all fungi tested caused greater weight losses in birch blocks than in pine blocks. Most fungi isolated from gymnosperms caused greater weight losses in pine than did isolates from angiosperms. The fungi studied produced two different types ofselective delignification. The first type resulted in extensive lignin removal from localized areas within wood blocks. The second type resulted in a more uniform loss throughout wood blocks, but less extensive loss from individual cell walls.read more

Effects of fungal degradation on the CuO oxidation products of lignin: A controlled laboratory study
TL;DR: In this article, the white-rot fungus Phlebia tremellosus was found to increase the H/C and O/C of the remnant wood by preferentially degrading the lignin component of the middle lamellae.

Screening for ligninolytic fungi applicable to the biodegradation of xenobiotics
TL;DR: Woody tissues are composed mainly of three biopoly- mers: cellulose; hemicellulose; and lignin, a highly irregular aromatic polymer which serves to pro- vide strength and structure to the tissue.

TL;DR: In this paper, a modification of the standard procedure for much smaller sample amounts was developed, which is based on the procedure of Saeman and is used for lignin analysis.

Screening wood decayed by white rot fungi for preferential lignin degradation.
TL;DR: This investigation demonstrates that selective delignification among white rot fungi is more prevalent than previously realized and identifies a large number of fungi for use in studies of preferential lignin degradation.

TL;DR: It is suggested that while-rot fungi, which preferentially degrade lignin, may be found among Group 2 fungi producing large amounts of phenol oxidases.
