Bacterial diversity dynamics in microbial consortia selected for lignin utilization
Fig 2
Family level taxonomic profile of bacteria at present in consortia obtained from MG soil over successive passages in enrichment experiment.
M9 medium containing either base-extracted lignin, BE Lig, (panels A and B) or Kraft lignin (panels C and D) was initially inoculated with MG soil (MG) as the source of microorganisms. Experiments were performed at two temperatures. 30°C (panels A and C) and 37°C (panels B and D). Every 2 weeks an aliquot was transferred to fresh growth medium for enrichment in successive passages (0, 1, 2, 3, 4, 5 and 6). Bacterial families are depicted by different colors. For the families classified as Other and Unknown, we were unable to obtain the taxonomic affiliation at the family level, so the closest previous hierarchical level is provided.
