Applied and Environmental Microbiology

The Schneegurt Laboratory works on a range of projects in applied and environmental microbiology.  A main focus has been the microbial ecology of hypersaline environments.  Substantial work was done at the Great Salt Plains of Oklahoma to isolate and characterize halotolerant and halophilic microbes, while defining the community with molecular methods.  This work was extended to salty environments (Hot Lake and Basque Lake) rich in magnesium sulfate (Epsom salts), as this is an important salt on Mars.  The astrobiology work impacts the search for life on Mars and forward planetary protection.  Related projects are examining the microbial ecology of dry and waxy bird feathers and flower nectars with high sugar contents.  While these environments are not salty, they have high osmotica and perhaps adapted microbial populations.  The group has been isolating halotolerant microbes from non-saline soils and examining microbial tolerance to perchlorates, also found on Mars.

The Schneegurt Laboratory continues to explore applied aspects of microbiology.  Work continued for many years on bioremediation of organic and inorganic pollutants, including polycyclic aromatic hydrocarbon degradation and the binding of metals to bacteria.  The group has been working on algal biodiesel production from two perspectives.  First is the molecular fingerprinting of microbial communities in simple open pond systems to understand the bacterial contamination process.  Second is work on producing algal biodiesel in the dark with the goal of using common fermenters and feedstocks.  The laboratory also collaborates with engineers on biofilm testing of novel nanomaterials and composite materials for biomedical devices.

The Schneegurt Laboratory has maintained an active outreach program in the public high schools in Wichita.  Here WSU students work in classrooms, mentoring students and teachers.  District-wide molecular forensics activities have been impacting more than 1000 students each year.  In addition, "Pass Me the Salt" research clubs are performing primary research at the schools.  Projects include mussel surveys of local rivers, discovery of bioactive compounds in prairie plants, aquatic toxicology of isoxaben, and household science applications.  Successful projects have led to presentations and mainstream peer-reviewed publications with high school teachers and students as authors.  The work with household materials has included microbiology systems and gel electrophoresis and eventually will provide an inexpensive suite of wet laboratory experiences that can be performed in many settings and would satisfy expectations for a high school or AP course in biology.
