Description of GEBA Organism (Learn more...)

Geneva College Biology and Chemistry Departments were selected by the JGI to help annotate the recently sequenced genome of the soil bacterium Pedobacter heparinus (P. heparinus).  Its genome has been subjected to pipeline annotation.  This is a GEBA bacterium and is a founding member of the genus Pedobacter.  P. heparinus is a aerobic gram negative rod which grows optimally at 25 degrees.  The bacterium exhibits colongy spreading on low nutrient and low percent agar plates presumably through a gliding mechanism.  A unique feature is that P. heparinus is capable of degrading heteromucopolysaccharhides such as heparin.  Enzymes purified from this species were helpful in mapping the structure of various types of heparins.   Interestingly, P. heparinus has been found in close proximity to the roots of several plant species including rice and certain dune grasses and may have a symbiotic or pathogenic relationship with these plants.
