Meeting/Event Information

Technical Talks: The Minnesota Section of AIPG holds technical talks September through May, generally the first Tuesday of the month. The talks are designed to fulfill 1 Professional Development Hour (PDH). Professional Geologists, as licensed in the State of Minnesota, are required to complete 24 PDHs every biennium licensing period, including 2 PDHs of ethics.  The technical talks feature important subjects of interest to professional geologists.

The cost includes a buffet lunch and is $21 for non-members, $16 for members, and $0 for students when registering in advance.  We have limited same-day registration for $25. 

*During the pandemic, we are webcasting our Technical Talks.  The cost is $10 for non-members and $5 for members. You must register by 11 AM the day of the talk to be sent the login link/information. Students may attend free of charge. Fees go toward supporting the online meeting platform and the Education Fund. Your contribution to the Education Fund helps support many activities, please see our Giving Back page.

As always, non-members and non-geologists are welcome to attend!

Using Common Soil Fungi to Remove Selenium from Industrial & Municipal Wastewaters!

by Mary Sabuda, M.Sc., Ph.D. Candidate, Department of Earth & Environmental Sciences, MnDRIVE & BioTechnology Institute, University of Minnesota

 

Presentation Abstract

Selenium (Se) plays a key role in human and ecosystem health as it is an important trace element for most life yet is an element of increasing environmental concern due to its toxicity in high concentrations. The bioavailability, toxicity, and mobility of Se through the environment is controlled by the form present. The Se forms common in oxic surface environments are Se(VI) and Se(IV), which are highly water soluble and bioavailable. Anthropogenic activities such as coal mining, processing, and combustion for electricity are especially problematic for increasing environmental Se concentrations to hazardous levels. Current strategies for removing Se from contaminated environments and wastewaters are expensive and inefficient, but recently some common soil fungi have been shown to efficiently remove Se from solution by reducing dissolved Se(+IV/VI) to form immobile solid Se(0) and less hazardous volatile Se(-II) under atmospheric conditions. Recent insights from bench scale culture experiments of these fungi grown under ideal (nutrient-rich) conditions, as well as in industrial (coal fly ash) and municipal (battery recycling) wastewater will be presented. As very little is understood about the chemical and genetic mechanism(s) of these fungal Se transformations over time, results from these studies will provide essential information for engineering an efficient, cost-effective Se bioremediation strategy.

 

Biography

Mary Sabuda has a bachelor’s degree in geology and a master’s degree in geomicrobiology from Michigan State University. She is currently a PhD candidate at the University of Minnesota (UMN) investigating the potential for common soil fungi to clean up contaminants such as selenium (Se) from polluted environments related to mining and other industrial processes. Se is an essential micronutrient for most organisms, however, excessive Se can cause serious pollution to the environment and bring severe risk and damage to human health. Mary combines her background in geology with molecular biology techniques to understand the metabolic pathways involved with fungal Se transformations, in order to optimize any future remediation strategy. Outside of her research, Mary is active in science communication and is currently a writer and editor for Sciworthy. She is also involved with a few women in science groups, including the Association of Women Geoscientists, and recently helped to organize the first Women in STEM summit at UMN to connect all advocates for women in science across campus.
