This dataset seeks to understand methanogenic and methanotrophic
processes and will be used to develop higher resolution and longer-term CH4 biogeochemical records over the Holocene and to better understand the effect of Asian monsoon change on modern and ancient CH4 biogeochemistry, and to ultimately embed them in the framework of known and hypothesised relationships between microorganisms and climate change.
Both soils show, on average, more methanotrophic
than methanogcnic activity, which resulted in C[H.
communities at deep-sea methane seeps (e.
A), and Serpiano (Switzerland) shales show the 2[alpha]- and 3[beta]-methylhopanes derived [22-24] from distinct bacterial sources: cyanobacteria (2-methyl) and methanotrophic
bacteria) are being consumed by mussels or that mussels selectively assimilate [sup.

activity that is particularly pronounced in forest soils (Smith et al.
Recently discovered biogeochemical processes also play important roles in the nitrogen cycle: anaerobic ammonia oxidation (Anammox) (van Loos-dtrecht & Jetten, 1998), heterotrophic nitrification (Robertson & Kuenen, 1990), aerobic denitrification (Robertson & Kuenen, 1990), methanotrophic
denitrification (Raghoebarsing et al.

Transformation yields of chlorinated ethenes by a methanotrophic

With the laboratory of Colin Murrell, work is progressing on cloning and sequencing the sMMO gene from various methanotrophic
cultures isolated in Canada and Germany.
The MGC project is one of 15 energy projects selected by the ARPA-E to participate in the agency s new REMOTE program (Reducing Emissions using Methanotrophic
Organisms for Transportation Energy).
