The lignocellulose-decomposing abilities of an actinomycete, Streptomyces viridosporus T7A, were studied in relation to the potential utilization of this strain for the bioconversion of lignin to useful chemicals. Both carbohydrate and lignin components were degraded. The grass and corn lignocelluloses were degraded much more extensively than the spruce and maple lignocelluloses; therefore the former were considered preferable as substrates for bioconversion. Both inoculated and control culture supernatants contained solvent extractible, phenolic, lignin-derived compounds with recoveries ranging between 3.1 and 12.2% of the initial lignin substrate. Lignin fragments that were identified included p-hydroxybenzoic acid, vanillic acid, protocatechuic acid, p-coumaric acid, syringic acid, ferulic acid, and the ketol (1-hydroxy-3-(4-hydroxy-3-methoxyphenyl)-2-propanone). The potential for using S. viridosporus in lignin to chemical bioconversions was discussed.
