通过在含有木质素化合物的培养基中培养白蚁（Nasutitermes takasagoensis）肠道中的细菌，获得了木质素在白蚁肠道中发生生物降解的直接证据。这些细菌能够降解木质素化合物。脱钾木质素的降解率为28%，木质素二聚体的降解率为60% ~ 95%，这些二聚体具有与木质素相适应的键，如β-O-4、β-1、苯香豆烷和联苯键。
By incubating bacteria from the gut of the termite, Nasutitermes takasagoensis, in a culture medium containing a ligninic compound, direct evidence that lignin-biodegradation occurs in the gut of termites was obtained. The bacteria were capable of degrading ligninic compounds. 28% of dealkalized lignin was degraded and lignin dimer compounds, which have a linkage proper to lignin, such as β-O-4, β-1, phenylcoumarane and biphenyl bonds, were degraded by 60 % to 95 %.
