This virtual issue of FEMS Microbiology Ecology is organized to link with the April 2013 FEMS Microbiology Reviews special thematic issue on Molecular Insights into Environmental Microbes.
Cutting-edge technology for genetic and biochemical analyses are playing an increasingly important role in contributing to the understanding of microbial ecology. We have selected key papers from the archives of FEMS Microbiology Ecology to complement the topics of the eight review articles that reflect on the activity of microbes in different environments. The topics range from life in symbiosis, commensalism, and syntrophy to life in soil, lakes and oceans. Much remains to be discovered and deciphered with regards to the diversity, growth, activity and interactions of microbial communities in different habitats and their important roles in global biogeochemical cycles and ecosystem function. The application and exploitation of modern molecular methods are essential in these ecological studies. As stated in the Editorial by Hauke Henneke, Staffan Kjelleberg and Corina Brussaard: “Environmental microbes will continue to provide an immense source for the discovery of novel life styles, new biochemical reactions and pathways, and unanticipated mechanisms of gene regulation.”
The articles highlighted here represent only a small selection of the exciting studies that we have published and for additional information and inspiration please search the past issues of FEMS Microbiology Ecology.
Trichodesmium – a widespread marine cyanobacterium with unusual nitrogen fixation properties

How to make a living from anaerobic ammonium oxidation
B. Kartal, N.M. de Almeida, W.J. Maalcke, H.J.M. Op den Camp, M.S.M. Jetten and J.T. Keltjens
FEMS Microbiology Reviews: Anaerobic ammonium-oxidizing (anammox) bacteria make their living from the conversion of ammonium and nitrite into dinitrogen gas using a new route. Here, current concepts on this new route are reviewed and its connection with energy (ATP) conservation and biomass formation is discussed.

Key microbial drivers in Antarctic aquatic environments

FEMS Microbiology Reviews: Antarctica is arguably the world's most important continent for influencing the Earth's climate and ocean ecosystem function, and this review puts into perspective the insight that has been and can be gained about Antarctica's aquatic microbiota by using molecular biology, and in particular, metagenomic approaches, by revealing deep insight into which microorganisms are present in cold environments, and what biogeochemical processes they perform
