Short communication: Isolation of a bacterium capable of limited degradation of industrial and labelled, natural and synthetic lignins

World J Microbiol Biotechnol. 1996 Jan;12(1):111-2. doi: 10.1007/BF00327817.


Pseudomonas putida, isolated from decomposing plant materials, degraded several lignin-related aromatic compounds. After 30 days of incubation in media containing polymeric Kraft-lignin (PKL), the amount of Klason lignin had decreased by about 13%. When (14)C-labelled dehydropolymers of coniferyl alcohol (DHP) lignins and (14)C-lignin-lignocelluloses were used as substrates, mineralization to (14)CO2 by the P. putida strain ranged from 1.4% to 2.1%.
