We are currently running the third temperature experiment in a year. This time we use an axenic strain of the coccolithophore Emilinia huxleyi and we grow it in three different temperatures; 15, 20, and 28°C. We will look at metabolites and gene expressions of the … Continue readingThe third temperature experiment
Wonderful Magnolia trees are in full bloom now and along with fall the most pleasant season here in Athens (GA, US).
We examined endometabolite production and transfer to surrounding bacteria by the cyanobacteria Synechococcus growing under three different temperatures; 20°C, 24°C, and 28°C. They all grew perfectly and were nice and pink at harvest in late exponential growth phase. We sampled for nuclear magnetic resonance (NMR) … Continue readingSynechococcus experiment
We have been growing the cyanobacteria Synechococcus at three different temperatures (20, 24, and 28°C) for many weeks now, tracking growth and planning for un upcoming experiment. Look at the picture and you will know where it grows fastest… So we now have three sets … Continue readingAdapting Synechococcus to different temperatures
We recently traveled along the Gulf Coast over the Thanksgiving holidays and the kids accidentally brought back a little friend. It is now called Bella and lives in a tank in our house. The kids are happy about their new pet and hopefully it want … Continue readingAn unexpected guest
I am happy to share that we recently were approved funding from JGI for six different metabolomics and metatranscriptomics experiments! It will involve temperature acclimation of three different species of phytoplankton co-cultured with both laboratory strains of heterotrophic bacteria and natural communities. There is a … Continue readingJGI Funded project!
We have a new paper out on phytoplankton diversity and how it varies across season and along a salinity gradient along the Swedish coastline. It is published in Scientific Reports and is a result of nice collaboration between SMHI, GU, and SLU.
Exciting times ahead, we are planning for a new experiment within the next couple of weeks. We will use our temperature acclimated diatoms to feed a natural bacterial community and trace the labile carbon transfers. There are a lot of logistics around this experiment but … Continue readingNew upcoming experiment
Earlier this week I was helping out in sampling for a Micromonas-bacteria co-culture experiment, conducted by the UGA graduate student Frank Ferrer-González. The experiment adress metabolite utilization by tracking substrates released by the green algae over time and using bacteria as biosensors to find out … Continue readingMicromonas matrix experiment
We moved to a new house in the middle of July here in Athens. Our contract with UGA housing run out and we now rent a nice condo near Bishop Park. We have a little garden where we grow Okra, tomatoes, beans, and bell pepper.
