Impact of metals on the biodegradation of organic pollutants.
Forty percent of hazardous waste sites in the United States are co-contaminated with organic and metal pollutants. Data from both aerobic and anaerobic systems demonstrate that biodegradation of theExpand

Rhamnolipid-Induced Removal of Lipopolysaccharide from Pseudomonas aeruginosa: Effect on Cell Surface Properties and Interaction with Hydrophobic Substrates
ABSTRACT Little is known about the interaction of biosurfactants with bacterial cells. Recent work in the area of biodegradation suggests that there are two mechanisms by which biosurfactants enhanceExpand

Bacterial Community Structure in the Hyperarid Core of the Atacama Desert, Chile
ABSTRACT Soils from the hyperarid Atacama Desert of northern Chile were sampled along an east-west elevational transect (23.75 to 24.70°S) through the driest sector to compare the relative structureExpand

Life at the hyperarid margin: novel bacterial diversity in arid soils of the Atacama Desert, Chile
Nearly half the earth’s surface is occupied by dryland ecosystems, regions susceptible to reduced states of biological productivity caused by climate fluctuations. Of these regions, arid zonesExpand
