| 31. | Lignin is thought to shield associated nutrients from digestion and hence limits degradation.
|
| 32. | Guaiacol is present in wood smoke, resulting from the pyrolysis of lignin.
|
| 33. | This leaves behind the fibreous parts such as cellulose, lignin and hemicellulose.
|
| 34. | The by-product of this process is lignin.
|
| 35. | Dihydroflavonol 4-reductase is an enzyme part of the lignin biosynthesis pathway.
|
| 36. | The homogeneous lignin polymer may be used as raw materials for other products.
|
| 37. | Oxidative enzymes such as phenol oxidase and peroxidase mediate lignin degradation and humification.
|
| 38. | Lignin removal from wood fibres conventionally relies on costly and environmentally hazardous chemicals.
|
| 39. | The fungus degrades the lignin present and increases the digestibility of the cellulose.
|
| 40. | When lignin breaks down, the wood deteriorates.
