The industrial production of paper and pulp from wood yields lignin (or spent liquors) as a by-product. This dark brown material is discharged as effluent in most operations. The authors very briefly discuss the microbiological and chemical degradation of lignin to determine which fungi are most effective in attacking it and what chemical sites are most susceptible to attack. In addition, the origin of the dark-colored substances that are produced by the chemical processes in wood pulping are discussed.
