| Temperature
extremes can make the difference between life and death, and yet little
is known about how proteins function at different temperatures. Other
researchers have studied enzymes that are active at extremely high
temperatures. Our objective is to discover and analyze novel
cold-active enzymes which have high activities at low temperatures and
to increase our understanding of how temperature affects enzyme
activity. We are also especially interested in characterizing microbes
from permanently cold environments and examining their ability to
metabolize at subzero temperatures, as in the Greenland ice sheet.

Vanya has recently analyzed ultra-small microbes from the Greenland ice core and will head the efforts on the Greenland Microbial Observatory. She also has worked extensively on characterizing both culturable and unculturable populations in Greenland ice. She has teamed up with Todd Sowers in the Geoscience department for her latest work. For Vanya's publications, look in Applied and Environmental Microbiology...She recently was an invited speaker at the International conference on Alpine and Polar Microbiology in Austria in 2006!

Jen Loveland-Curtze has worked on the characterization of a novel genus of bacteria designated LV3. This genus is unique in its appearance due to bulbous protuberances seen during growth. It's characterization is detailed here.
Catherine Teacher has been preparing clone libraries from the Greenland Ice Sheet Project. She often calls herself the muscle behind Vanya's brain. |
Jen
Biddle is working on samples obtained during Leg 201 of the Ocean
Drilling Program which sampled areas off the coast of Peru. Jen hopes
to identify cold active microbes in these core samples. She also is using
FISHSIMS to determine metabolic activities of uncultured microbes. Her co-advisor
in this project is Chris House
in the Geological Sciences Department.
Look for Jen's publications in PNAS and Geobiology. |
