Congratulations go to Mike for being awarded a Lerner-Gray Grant for Marine Research from the American Museum of Natural History. Mike will use the grant to explore the use of Oxford Nanopore sequencing to conduct coastal gene expression surveys for various abundant SAR11 bacteria, including LD12. An excellent accomplishment!
For the past four months a crew of four rowers and four shore crew members with OAR Northwest, a not-for-profit adventure education organization, have been on a journey of a lifetime on the Mississippi River. After over 100 days of rowing, the crew has traveled from the headwaters of the River in Minnesota to the Gulf of Mexico. They arrived in Baton Rouge on November 16, 2016 and spent a few days visiting LSU and talking to students about their journey.
Just as the state of Louisiana has a special connection with the “Mighty” Mississippi River, the OAR Northwest rowing crew has a special connection with LSU. This is the second OAR Northwest Mississippi River adventure during which rowers have collected water samples for Dr. Cameron Thrash, an assistant professor in the LSU Biological Sciences department. Cameron’s research focuses on relationships between microorganisms and biogeochemical cycles, particularly in marine systems. Thanks to a relationship with the OAR Northwest team that started when founder Jordan Hanssen met Cameron’s family in Washington, and which has developed into an ongoing citizen science project, the Thrash lab is now building a complete microbial “map” of the Mississippi river…
Emily presented her LA Sea Grant-funded work to characterize one of our coastal isolates from the OM252 clade, LSUCC0096. She showed this organism has remarkable salinity tolerance, and can grow under chemolithoautotrophic conditions, a feature that was predicted from genome analysis.
Celeste presented results of her experiment to enrich for microorganisms that could utilize fulvic acids as their sole carbon source. She compared her work to that of former lab member Jessica Weckhorst who performed a similar experiment with humic acids. These are both extremely important fractions of the marine DOC pool.
We have a little bit of press coverage here at LSU. See the post on our work at the College of Science website HERE.
Mike and I went on a sampling trip Tuesday (1/12/16) to the Mississippi Delta (“The Birdfoot”) near Buras, LA. This was my first sampling trip ever with the Thrash lab, and I must say that it was a great experience! We headed out loaded up with our equipment and coffee, and ended up with a fantastic view of the sunrise at the edge of Lake Pontchartrain. Sadly, the picture does not come close to the beauty of our actual view.
At the site, Mike waded out into the water to collect the sample while I got to hang back and enjoy the scenery. It was a great day to be outdoors with cool air and the sun shining.
Overall, I really enjoyed my sampling adventure with Mike. This trip was a part of our 3 year study of the coastline to characterize the microbial population of the Louisiana coast in conjunction with adding microbes to our Louisiana State culture collection (LSUCC) from the Gulf of Mexico. I’m hopeful that we will isolate some novel organisms from this and future trips. Not all undergraduates are lucky enough to be a part of a lab that allows us to be out in the field for data collection, so I’m grateful to Dr. Thrash and Mike for the opportunity!
