BACKGROUND: Many polycyclic aromatic hydrocarbon (PAH) contaminated sites also contain high levels of toxic heavy metals. The presence of heavy metals can adversely affect PAH biodegradation. Encapsulation of bacterial cells has been shown to improve

The effect of PCP and NaPCP on the cytoplasmic membranes of the PCP-mineralizing bacterium Sphingomonas sp. UG30 was assessed using fluorescence polarization and total cellular fatty acid analysis. Direct exposure of resting UG30 cells to PCP up to 2

Ralstonia solanacearum biovar 2, the causative agent of brown rot in potato, has been responsible for large crop losses in Northwest Europe during the last decade. Knowledge on the ecological behaviour of R. solanacearum and its antagonists is requir

The effect of alterations in fatty acid composition and fluidity of cell membranes on the accumulation of PCB congener 2,2′,5,5′-tetrachlorobiphenyl (TeCB) by Ralstonia eutropha (formerly Alcaligenes eutrophus) H850 was studied. Cells of R eutrop

Bacteria are ubiquitous in the natural environment, even when nutrients are limiting and they are in a physiological state of starvation-survival. How bacterial cells survive for extended periods of time when the nutrients and energy needed for growt

Five bioassays were used to measure toxicity during bioremediation of a soil contaminated with pentachlorophenol (PCP; 335 ppm), polycyclic aromatic hydrocarbons (PAHs; 1225 ppm) and petroleum hydrocarbons (19 125 ppm). Different bioremediation treat

Lac-lux marked Pseudomonas aeruginosa UG2Lr cells were encapsulated in alginate or a novel κ -carrageenan formulation. The beads were dried and maintained at 4°C in the dark. Plate counts determined that survival of encapsulated cells, after an ini

A contaminated soil from Ontario, Canada containing 350–370 ppm pentachlorophenol (PCP) and 21000 ppm total petroleum hydrocarbons (TPH) was inoculated with PCP-degrading Pseudomonas sp UG30 cells either encapsulated in κ κ-carrageenan or as free

A pentachlorophenol(PCP)-degrading Pseudomonas sp. strain UG30 was encapsulated in κ-carrageenan for use in PCP degradation. Free and encapsulated cells were compared for their ability to dechlorinate and mineralize 100–800 μg/ml sodium pentachlo
