Julie has been hanging out in the lab

Don’t worry everyone, I haven’t broken anything (yet).

The Actinobacteria are growing respectably once again. I’m extracting DNA from these pellets so Janae can do some cloning, but the next experiment will be co-cultivation with Synechocystis.

 

 

 

 

 

 

 

 

 

 

 

 

 

This is Bacillus sp. S4, which makes antifungal compounds. Lab PhD alum Mengyin Yao isolated it, and Sarah Yannarell showed that it had antifungal activity. Next steps: a little further characterization of the antifungal compound in Nicole Donofrio’s lab, and genome sequencing!

Farewell Hannah!

This summer, we welcomed Hannah Tompkins a student at Whitworth University. She was a wonderful addition and we wish her all the best in her future work!

Hannah is currently completing a dual degree in Physics at Whitworth University and Chemical Engineering at Washington University in St. Louis. This summer she worked as an intern to quantify how bacteria isolated from concrete induce precipitation of calcium carbonate for the application of bio-repair of concrete. Her work included assessing the growth of such bacteria in conditions of low water availability to determine their viability for bio-repair in the harsh environment of concrete. In her free time, she enjoys hiking, shopping at Trader Joe’s, and convincing people to wear Hawaiian shirts on Fridays.

The UD CEE External Advisory Council Meeting

Maresca lab members attended The 2019 University of Delaware Civil and Environmental Engineering External Advisory Council Meeting.  Anders presented a poster, “Detection of Alkali-silica Reaction in Concrete with Microbial Bioindicators” and Emma presented a poster, “Physical and Biological Two-Step Degradation of Long-Chain Perfluoroalkyl Substances”.

 

 

 

 

 

 

 

 

 

 

Professional Development Awards

Congratulations to Priscilla and Anders who have won University of Delaware Office of Graduate and Professional Education Professional Development Awards to attend the 2019 Applied and Environmental Microbiology Gordon Research Seminar and Conference in July.

Emma attended The Future of Water in the Mid-Atlantic Symposium

Emma presented her poster, “Potential for Degradation of Long-Chain Perfluoroalkyl Substances” at the 2019 Human and Climate Series II: Future of Water in the Mid-Atlantic: Agriculture, Restoration and Technology Symposium at Stroud Water Research Center in Avondale, PA.

UD DENIN and Stroud Water Research Center in Avondale, Pennsylvania joined together for an all day symposium titled “Future of Water in the Mid-Atlantic: Agriculture, Restoration and Technology” on March 22, 2019.

The 2019 DENIN Environmental Symposium

Maresca Lab attended the 2019 DENIN Environmental Symposium. Emma presented a poster, “Potential for Degradation of Long-Chain Perfluoroalkyl Substances” and Priscilla gave a talk, “Cryptic Light-Enhanced Growth in Heterotrophic Actinobacteria”.

The annual DENIN Graduate Student Symposium for 2019 took place in the ISE Lab on Thursday, March 7th and featured several brief talks and a judged poster session. – (Evan Krape / University of Delaware)
