Bloom or Bust? Two Sides of Blue-Green Algae

Bloom or Bust? Two Sides of Blue-Green Algae

Dr. Annaliese Franz, PhD. Associate Professor of Chemistry

 

By Lisa Justice

Special to the Enterprise

 

Explorit’s Science Lecture series is off to a robust start this spring with a variety of environmental topics. Join us for the next installment on Thursday, March 3 as we tackle the tricky issue of blue-green algae.

 

Why should we be interested in these algae? For many important reasons, one of which is that this year's toxic algal bloom spreading off California's Pacific coast could be the largest one scientists have ever seen. Animal rescue centers along the coast are seeing an unusual increase in sea lion, dolphin and pelican deaths.

 

We will explore this complex issue from multiple sides with a joint presentation, “Blue-Green Algae: The Good, The Bad, and The Ugly,” by Drs. Annaliese Franz and Bob Poppenga.

 

Microscopic algae (microalgae) are amazing little green photosynthetic factories that can produce a type of oil that can be converted to biodiesel fuel.  Dr. Franz's research uses several approaches to improve biofuel production from algae, and also investigates how these microalgae can be grown using wastewater as a source of nutrients so that the process is helping to purify the water at the same time as it is producing oil to be converted to biodiesel. This research also highlights the great teamwork that can exist between chemists, biologists and engineers.  

 

On the flip side, many microalgae species produce potent toxins that can harm humans and animals. These toxins are produced by algae following rapid growth in a body of water.  

 

The accumulation of millions of microscopic algal cells in water can be seen as a bluish-green scum on or near the water surface. These are called algal “blooms”.  Toxic blooms occur in water impacted by environmental nutrient loading, primarily fertilizer run-off.  

 

Exposure of people and animals to these blooms can cause rapid onset of illness and death. Dr. Poppenga's laboratory tests animal and water samples for the most common algal toxins and helps water agencies identify problems before harm occurs.   

 

Together Franz and Poppenga will lead us through this fascinating and multilayered phenomenon. Dr. Annaliese Franz received her B.S. degree in Chemistry from Trinity University in San Antonio, TX, and her Ph.D. in Chemistry from UC Irvine in 2002. In 2007, Annaliese started as an Assistant Professor in the Chemistry Department at UC Davis, and was promoted to Associate Professor in 2013. Dr. Franz is passionate about education and mentoring students in many programs on campus.

 

Dr. Robert Poppenga is Professor of Clinical Veterinary Toxicology and Section Head, Toxicology Laboratory at the California Animal Health and Food Safety Laboratory (CAHFS), School of Veterinary Medicine, University of California at Davis.  An Illinois native, he received his veterinary and PhD degrees from the University of Illinois at Urbana. The Toxicology Laboratory at CAHFS is one of the busiest of its kind in the world and offers comprehensive diagnostic toxicology testing.

 

Be sure to bring your questions and your curiosity! This lecture will be hosted at the DMG Mori auditorium at 3805 Faraday Ave. in Davis, on Thursday, March 3 at 7:00 p.m.
