Reseña del editor

The oil crisis during the 1970s turned interest towards the utilization of renewable resources and towards lignocellulosics in particular. The 1970s were also the cradle period of biotechnology, and the years when biotechnical utilization of lignocellulosic waste from agriculture and forestry gained priori­ ty. This was a logical conclusion since one of nature's most important biologi­ cal reactions is the conversion of wood and other lignocellulosic materials to carbon dioxide, water and humic substances. However, while biotechnology in other areas like medicine and pharmacology concerned production of expen­ sive products on a small scale, biotechnical utilization and conversion of ligno­ cellulosics meant production of inexpensive products on a large scale. Biotechnical utilization of lignocellulosic materials is therefore a very difficult task, and the commercial utilization of this technology has not progressed as rapidly as one would have desired. One reason for this was the lack of basic knowledge of enzyme mechanisms involved in the degradation and conversion of wood, other lignocellulosics and their individual components. There are also risks associated with initiating a technical development before a stable platform of knowledge is available. Several of the projects started with en­ thusiasm have therefore suffered some loss of interest. Also contributing to this failing interest is the fact that the oil crisis at the time was not a real one. At present, nobody predicts a rapid exhaustion of the oil resources and fuel production from lignocellulosics is no longer a high priority.

Reseña del editor

This detailed review describes the biochemical mechanisms involved in the biodegradation of wood and the wood components, cellulose and hemicellulose, as well as lignin by fungi and bacteria. Main topics are: * Biosynthesis and structure of the wood components; * Description of the various fungal and bacterial enzymes involved in the degradation of wood components and their mode of action; * The possibilities for biotechnology based on microorganisms or their enzymes degrading wood and wood components.
