This is something biofuels need

One of the big hang-ups for turning vegetative feedstocks into biofuels is the lignin content, the stuff that isn't cellulose. Lignin does not break down or degrade easily, and this is not easily digestible by digesters. Well, the enzymatic breakthrough for the breakdown of lignin might be something that the biofuel industry has really needed.

First wood-digesting enzyme found in bacteria could boost biofuel production

Professor Timothy Bugg, from the University of Warwick, who led the team, said “For biofuels to be a sustainable alternative to fossil fuels we need to extract the maximum possible energy available from plants. By raising the exciting possibility of being able to produce lignin-degrading enzymes from bacteria on an industrial scale this research could help unlock currently unattainable sources of biofuels."
