Methanogenic archaea: ecologically relevant differences in energy conservation
Rudolf K. Thauer, Anne-Kristin Kaster, Henning Seedorf, Wolfgang Buckel and
Reiner Hedderich
p579 | doi:10.1038/nrmicro1931
Methanogenic archaea with and without cytochromes have been identified.
This Review focuses on differences in energy conservation during the reduction
of CO2 with H2 to CH4. In methanogens with cytochromes, the first and last steps
are coupled chemiosmotically, and the authors propose that in methanogens without
cytochromes, these steps are coupled by a cytoplasmic enzyme complex that mediates
flavin-based electron bifurcation.

The shewanellae are masters of metabolism and can catabolize numerous carbon sources
either aerobically or anaerobically using a range of electron acceptors. Ubiquitous
among microbial communities from marine to soil environments, this genus is important
in carbon cycling and bioremediation. Systems-biology approaches could shed new light
on the ecophysiology of these bacteria.

Pre-genomic, genomic and post-genomic study of microbial communities
involved in bioenergy
Bruce E. Rittmann, Rosa Krajmalnik-Brown and Rolf U. Halden
p604 | doi:10.1038/nrmicro1939
Microbial bioenergy could be used to generate large amounts of carbon-neutral
alternatives to fossil fuels. This article discusses the contribution of genomic
resources to the generation of bioenergy by bacteria and archaea.

Carbon catabolite repression in bacteria: many ways to make the most out of nutrients
Boris Gorke and Jorg Stulke
p613 | doi:10.1038/nrmicro1932
Using the process of carbon catabolite repression (CCR), bacteria control
gene expression and protein activity to preferentially metabolize the
carbon sources that are most easily accessible and allow fastest growth.
Recent findings have provided new insight into the mechanisms that different
bacteria use to control CCR.

Mechanisms of microbial traversal of the blood-brain barrier
Kwang Sik Kim
p625 | doi:10.1038/nrmicro1952
Central nervous system infections are an important cause of morbidity and mortality.
Here, Kwang Sik Kim summarizes our current understanding of the mechanisms that are
involved in traversal of the blood-brain barrier by selected meningitis-causing
microorganisms.

Establishing bacterial communities by 'word of mouth': LuxS and autoinducer 2
in biofilm development
Kim Rachael Hardie and Karin Heurlier
p635 | doi:10.1038/nrmicro1916
Autoinducer 2 (AI2) is the only quorum-sensing signal that is shared by Gram-negative and
Gram-positive bacteria. Because AI2 biosynthesis, specified by the luxS gene, is linked
to S-adenosyl homocysteine recycling, determining whether luxS biofilm phenotypes are
due to signalling or effects on bacterial metabolism is not straightforward, and is
discussed here.
