Briefly describe
overall research program at your laboratory:
The
focus of my research is on microbial kinetic
analysis and bioreactor design for bioconversion processes used for
environmental applications (reduction of nutrient and substrate
concentrations)
and bioprocessing (production of specialty chemicals such as
nutraceutical and
pharmaceutical compounds and biofuels using agricultural residues and
biomass).
Blooms of algae in
freshwater environments are stimulated by nutrient inputs from a
variety of
pollution sources. Lake Greenwood is a popular recreational
waterbody that has been impacted by dense algal blooms. These
blooms
occur with increasing severity despite decreasing concentrations of
nutrients
in the water column, indicating that sediment nutrient content may be
triggering the blooms. After conducting a literature review of water
quality
data and predominant naturally-occurring algal species in the lake,
four phases
of research are planned. These phases are:
1) conducting a field
assessment of
naturally-occurring algae in the lake considering spatial and seasonal
affects,
as correlated to sediment nutrient content, if not present in the
literature;
2) a laboratory kinetic analysis of the algal growth rate as a function
of
sediment phosphorus content;
3) a lab-scale investigation of a
biological
reactor designed to reduce soluble phosphorus content in the lake; and
4) an
investigation of high-value products, such as sulfolipids, that may be
present
in the naturally-occurring algae, that could be extracted for
biotechnology
applications.
Josefin, Kelly and Michael
will focus on Phases 1, 2 and 3 of the research, with a future student
conducting the Phase 4 of the research. Josefin,
Kelly and Michael are all seniors in Biosystems
Engineering at
CU , in the Natural Resources concentration area.
