Abstract
Forty‐two white‐rot fungi isolated in South America were incubated with long fibre sugar cane bagasse (LFB). The residual composition of LFB was determined after white‐rot decay at 30 and 60 days. The ratio of residual lignin to residual lignin to residual cellulose (RL/RC) of untreated material (LFB) was 0.48. After white‐rot‐decay, the residual material with lower RL/RC ratios indicated that mainly lignin was degraded. In only 30 days,Phlebiasp. MVHC 5535,Atheliasp. MVHC 5509 andSpongipellis pachyodonMVHC 5019 caused a decrease in the RL/RC ratio to 0.36, 0.37 and 0.38, respectively, while it took 60 days forGanoderma applanatumMVHC 5347,Hyphodontiasp. MVHC 5544,Panus tigrinusMVHC 5400,Stereumsp. MVHC 5113,Phellinus punctatusMVHC 5346 and MVHC 6388 to reach a ratio lower than 0.40. No correlation was found between the amount of some ligninolytic enzymes secreted and the residual composition of bagasse after white‐rot fungi fermentation. Most of the fungal strains caused an increase in the relative amount of residual cellulose, indicating that hemicellulose was the preferred energy source.
