Isolation and characterization of isopimaric acid-degrading bacteria from a sequencing batch reactor
Article Abstract:
The isopimaric acid (IpA) -1 and IpA-2 gram-negative bacterial strains, isolated from a sequencing batch reactor in a paper mill, are able to use IpA as an electron and carbon source. The strains also grow on dehydroabietic acid and pimaric acid, and use fatty acids. During growth, the strains convert the IpA carbon to equal amounts of biomass, carbon dioxide and dissolved organic carbon. Growth on IpA stimulates an enzymatic system causing the cell suspensions to change the resin acids. The 16S rRNA analyses show that these strains are members of the genus Pseudomonas.

Psychrotolerant bacteria isolated from arctic soil that degrade polychlorinated biphenyls at low temperatures
Article Abstract:
A study was conducted to isolate and characterize polychlorinated biphenyl (PCB)-degrading psychrotolerant bacteria from PCB-contaminated Arctic soil. Arctic soil isolates were determined at 7 degrees C while Burrkholderia cepacia LB400 was grown at 15 degrees C in 1-liter cultures. Gram staining, cell size and motility tests were then carried out on liquid cultures in late-logarithmic phase. Results showed that PCB bioremediation can effectively remove PCBs at high initial rates without heating.

Aerobic biodegradation of biphenyl and polychlorinated biphenyls by arctic soil microorganisms
Article Abstract:
Microbiological research indicates that microorganisms which tolerate and degrade the polychlorinated biphenyl (PCB) mixture Aroclor 1221 could be used in bioremediation work at warm or cold temperatures. Aroclor 1221 removal from cold soils was disappointing. However, evidence suggests that improved biodegradation of PCBs could be achieved in low temperature arctic soils with further research.
