Mon defended her PhD

Amelia Rotaru

At the end of November 2019, Mon successfully defended her Ph.D. She did a beautiful job in front of an expert committee including A/Prof. Annette Rowe (Uni. Cincinnati), A/Prof. Diana Sousa (Uni. Wageningen) and chaired by Prof. Don Canfield (SDU). Also, right before the defense, we got the good news that two articles included in Mon’s thesis were accepted for publication. Two days later, Mon took up a new challenge and started a postdoc at the LBNL (Laurence Berkeley National Labs, CA, USA). She’s now up to other exciting adventures in the environmental microbiology of deep biosphere and rhizosphere.

Preprint 1st of Nov 2018: Extracellular electron uptake by two Methanosarcina species

Amelia Rotaru

My first Ph.D. student Mon Oo Yee just preprinted her first paper: Extracellular electron uptake by two Methanosarcina species. Mon discovered that although two different Methanosarcina could do DIET, they differed in their capability to do electromethanogenesis at a fixed cathode potential. We are excited to hear how the scientific community receives her work.

New paper on odd partnerships fused by conductive particles and workshop in Wageningen

Amelia Rotaru

Finally, great to see our BioRxiv paper just published by mBio. Also, SDU Nat’s press officer (Birgitte Svennevig) published a EurekaAlert and a press release on SDU’s website calling attention to our work. This work is a contribution to a project funded by the Danish Research Council in 2013. Wageningen: a sneak peak at conductive particle-mediated syntrophy Just before the paper was released I visited Wageningen University were I held a workshop and lecture on conductive particle-mediated syntrophy. It was an absolutely fantastic experience to lecture on syntrophy at a place where syntrophy has been studied for decades. The Wageningen visit was only possible…Continue readingNew paper on odd partnerships fused by conductive particles and workshop in Wageningen

Preprint from our lab

Amelia Rotaru

We discovered that Baltic Sea consortia rich in Geobacter and Methanosarcina carried out syntrophic acetate oxidation (SAO) mediated by conductive particles.  It’s a really exciting finding not only because it is of importance to our understanding of the iron the methane cycles but also because: it raises questions how anthropogenic discharge of conductive particles (from agriculture, forestry etc) affects methane emissions it can explain the presence of electrogens like Geobacter in the methanogenic zone it can explain isotope ratios characteristic of CO2 reductive methanogenesis in deep sediment layers where Methanosarcina (an acetoclastic methanogen) is abundant it is the first detailed description of…Continue readingPreprint from our lab
