Almost every year, international symposia on wood or lignin chemistry are held in some part of the globe and the transactions recorded in journals or in book form. Recent meetings include those at Atlantic City... 

Almost comprehensive and largely unbiased references to original publications and patents in lignin chemistry up until about 1959 can be found in the books by Brauns (and wife) 20, 21 ) more recent papers are listed almost in full in the annual reviews of lignin by Pearl 120, 121).

This paper was prepared based on our recent work on lignin biodegradation in the Research Section of Lignin Chemistry. The author is indebted to Dr. M. Shimada, Dr. T. Umezawa, Messrs. S. Kawai, T. Habe, S. Yokota and... 

Figure 1. /3-0-4 lignin substructure model dimers 1-4 and their degradation by white-rot fungi, Phanerochaete chrysosporium, Coriolus versicolor, and Coriolus hirsutus. The ether bond between the C/ and the B-aromatic nucleus is referred to as /3-0-4 bond in lignin chemistry. 

One of the basic assumptions is that all calculations are done on isolated gas-phase molecules. This is obviously a large shortcoming for lignin chemistry for a number of reasons. The reactions of importance in lignin... 

From this brief introduction, it is obvious that the execution of the calculations and the interpretation of the results are still in their initial stages. It is the contention of the author that the insight into lignin chemistry that may be obtained by these methods deserves careful consideration.
