Stabilization of microorganisms for in situ degradation of toxic chemicals. Progress report

Technical Report ·
OSTI ID:10180072
;
In our initial work, we have developed methods to microencapsulate cells within beads of 5--100,{mu}m diameter, and we have examined these entrapped cells for their abilities to mineralize specific chemicals in the presence of subsurface soils and waters obtained from the University of Idaho Groundwater Research Site (GRS). We have employed a pentachlorophenol (PCP)-degrading Flavobacterium and a toluene-degrading Pseudomonas. Cells were immobilized within one of three polymeric matrixes: alginate, agarose, or polyurethane.
