Microbiology: Woodworker's digest

Andreas Brune1

Termites digest wood with the help of their intestinal microorganisms. The first metagenomic analysis of the inhabitants of a termite gut provides insight into this feat of biomass-to-energy conversion.

The gut of wood-feeding termites is a tiny but astonishingly efficient bioreactor, in which microbes catalyse the conversion of lignified plant cell walls to fermentation products that drive the metabolism of their host. Molecular phylogenetic data have revealed the presence of hundreds of microbial species in this microlitre-sized environment, but little is known about their functional diversity.
