The sequence of changes observed microscopically that occurred in wood throughout successive stages of decay was studied in the sapwood of a hardwood, sweetgum (Liquidambar styraciflua L.), and of a softwood, southern pine (Pinus sp.). The fungi used were Polyporus versicolor L. ex Fr., a white-rot fungus, and Poria monticola Murr., a brown-rot fungus. Light microscopy, plus the techniques of polarization and ultraviolet-absorption microscopy, was used to make the observations on sections 4 microns thick cut from celloidin-embedded specimens.

Wood-destroying fungi play an important role in nature, because they are the only forms of life capable of reducing wood to its initial constituents. However, they can also be dangerous for people and property, as they can impair the stability and fracture-safety of trees. This book gives detailed information, based on new and original scientfic findings, on the examination and effects of the most important species of fungi associated with failure of infected urban trees. In addition, new ways are presented for predicting the advance of decay in the living tree. The subject is illustrated and made easily accessible by numerous colored photos of fungus fruit bodies, defect symptoms, and macroscopic and microscopic pictures of wood decay. A detailed introduction to the fundamentals of wood pathology provides a way into the subjects of applied mycology and tree care for readers without previous special knowledge. Francis W.M.R.

Wood and other structural lignocellulose biomaterials are renewable resources that provide sustainable products that require considerably less energy to manufacture into useable products than other alternatives produced from nonrenewable resources. However, these materials are readily biodegradable and as such must be protected if they are to be used in adverse environments. Consequently, their protection through chemical and nonchemical means plays a vital role in the satisfactory utilization of many products. This publication represents the third ACS book by the three co-editors in a series addressing scientific and practical aspects of biodeterioration and protection of lignocellulose materials. The objective of this third book diverges to some extent from the prior texts, in that it provides an overall view of our current understanding of the microbial and thermal degradation of plant biomass along with new developments in the rapidly changing field of wood protection. The latter is particularly important in light of dramatic changes in copper-based wood preservative systems that are used extensively to treat wood for residential construction, and in the commercial development of lignocellulose modification processes that protect bio-based materials without the addition of biocides. These changes, along with an update on new organic wood preservative systems, factors influencing wood biodeterioration above ground and in soil contact, wood treatment processes, registration and approval processes, applications of molecular biology in wood protection research, and the conversion of biomass into high value carbon products and worldwide trends in wood protection, are covered in this latest ACS book. The individual chapters were authored by a world-class group of academic and industrial scientists in order to provide a state-of-the-art review and global perspective of this rapidly changing field and reviewed by internationally recognized scientist

Advances in Enzymic Hydrolysis of Cellulose and Related Materials documents the proceedings of a symposium held in March 1962. This book emphasizes the interests of contributors actively engaged in production and properties of the enzymes and cellulose decomposition. Despite the significance of enzymes, relatively little work has been done on this group of enzymes, which include cellulases, hemicellulases, xylanases, disaccharidases, and glycosidases. This compilation aims to have the biological aspects of celluloses and hemicelluloses recognized under the cellulose field, and the cellulases to be considered in future books about cellulose and wood. Other topics discussed in this selection include structural features of cellulose that influence its susceptibility to enzymatic hydrolysis; purification of cellulase and related enzymes; endwise degradation of cellulose; and applications for cellulases. This publication is beneficial to students and researchers conducting work on enzymes and cellulose decomposition.
