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.
Initially planned to start 1st of April, now started 1st of July, after three months delay. Finally we known the diatom experiment in 14°C, 20°C, and 28°C, using Thalassiosira pseudonana together with Ruegeria pomeroyi. It will later on be exciting receiving data on endo- and … Continue readingDiatom experiment is up and running
After months at home, except for monitoring of algal cultures, UGA is now in phase 1 opening stage. This includes masks, frequent hand and surface sanitation, and staggered lab schedules. Anyways, its great to be back!
