| Abstract: | Lignin in marine sediment is a good biomarker of terrestrial organic carbon(TOC) input,while the biodegradation during the transportation and burial into sediment will affect its indicative use.In this review,first,the structure,the degradation microorganism and mechanism of lignin were briefly introduced,then the change of lignin indicative parameters during the biodegradation which affect the use of it as a biomarker were focus on.Finally,the solution to the problem was summarized and that in order to get an unequivocal sound conclusion was suggested,multiple approaches should be combined to obtain more information. |
