Resumen:
Lignocellulosic biomasses, either from non-edibleplants or from agricultural residues, stock biomacromoleculesthat can be processed to produce both energyand bioproducts. Therefore, they become major candidatesto replace petroleum as the main source of energy. However,to shift the fossil-based economy to a bio-based one,it is imperative to develop robust biotechnologies to effi-ciently convert lignocellulosic streams in power and platformchemicals. Although most of the biomass processingfacilities use celluloses and hemicelluloses to producebioethanol and paper, there is no consolidated bioprocess toproduce valuable compounds out of lignin at industrialscale available currently. Usually, lignin is burned to provideheat or it remains as a by-product in different streams,thus arising environmental concerns. In this way, thebiorefinery concept is not extended to completion. Due toNature offers an arsenal of biotechnological tools throughmicroorganisms to accomplish lignin valorization ordegradation, an increasing number of projects dealing withthese tasks have been described recently. In this review,outstanding reports over the last 6 years are described,comprising the microbial utilization of lignin to produce avariety of valuable compounds as well as to diminish itsecological impact. Furthermore, perspectives on thesetopics are given.
