Production of N2through Anaerobic Ammonium Oxidation Coupled to Nitrate Reduction in Marine SedimentsApplied and Environmental Microbiology - Tập 68 Số 3 - Trang 1312-1318 - 2002
Bo Thamdrup, Tage Dalsgaard
ABSTRACTIn the global nitrogen cycle, bacterial denitrification is recognized as the only quantitatively important process that converts fixed nitrogen to atmospheric nitrogen gas, N2, thereby influencing many aspects of ecosystem function and global biogeochemistry. However, we have found that a process novel to the marine nitrogen cycle, anae...... hiện toàn bộ
Biocontrol of Listeria monocytogenes on Fresh-Cut Produce by Treatment with Lytic Bacteriophages and a BacteriocinApplied and Environmental Microbiology - Tập 69 Số 8 - Trang 4519-4526 - 2003

ABSTRACT
The fresh-cut produce industry has been the fastest-growing portion of the food retail market during the past 10 years, providing consumers with convenient and nutritious food. However, fresh-cut fruits and vegetables raise food safety concerns, because exposed tissue may be colonized more easily by pathogenic bacteria than intact pr...... hiện toàn bộ
Virulent Bacteriophage for Efficient Biocontrol of Listeria monocytogenes in Ready-To-Eat FoodsApplied and Environmental Microbiology - Tập 75 Số 1 - Trang 93-100 - 2009

ABSTRACT
Food-borne
Listeria monocytogenes
is a serious threat to human health, and new strategies to combat this opportunistic pathogen in foods are needed. Bacteriophages are natural enemies of bacteria and are suitable candidates for the environmentally friendly biocontrol of these pathoge...... hiện toàn bộ
Effects of Nickel and Cobalt on Kinetics of Methanol Conversion by Methanogenic Sludge as Assessed by On-Line CH 4 MonitoringApplied and Environmental Microbiology - Tập 65 Số 4 - Trang 1789-1793 - 1999
G. Gonzalez‐Gil, Robbert Kleerebezem, G. Lettinga
ABSTRACT
When metals were added in a pulse mode to methylotrophic-methanogenic biomass, three methane production rate phases were recognized. Increased concentrations of Ni and Co accelerated the initial exponential and final arithmetic increases in the methane production rate and reduced the temporary decrease in the rate. When Ni and Co were added conti...... hiện toàn bộ
A Rhamnolipid Biosurfactant Reduces Cadmium Toxicity during Naphthalene BiodegradationApplied and Environmental Microbiology - Tập 66 Số 10 - Trang 4585-4588 - 2000
Todd R. Sandrin, Andrea M. Chech, Raina M. Maier
ABSTRACT
A model cocontaminated system was developed to determine whether a metal-complexing biosurfactant, rhamnolipid, could reduce metal toxicity to allow enhanced organic biodegradation by a
Burkholderia
sp. isolated from soil. Rhamnolipid eliminated cadmium toxicity when added at a 10-fo...... hiện toàn bộ
Effect of added heavy metal ions on biotransformation and biodegradation of 2-chlorophenol and 3-chlorobenzoate in anaerobic bacterial consortiaApplied and Environmental Microbiology - Tập 62 Số 7 - Trang 2317-2323 - 1996
Cheng-Lung Kuo, Barbara R. Sharak Genthner
The effect of added Cd(II), Cu(II), Cr(VI), or Hg(II) at 0.01 to 100 ppm on metabolism in anaerobic bacterial consortia which degrade 2-chlorophenol (2CP), 3-chlorobenzoate (3CB), phenol, and benzoate was examined. Three effects were observed, including extended acclimation periods (0.1 to 2.0 ppm), reduced dechlorination or biodegradation rates (0.1 to 2.0 ppm), and failure to dechlorinat...... hiện toàn bộ
Biodegradation of Methyltert-Butyl Ether by a Pure Bacterial CultureApplied and Environmental Microbiology - Tập 67 Số 12 - Trang 5601-5607 - 2001

ABSTRACTBiodegradation of methyltert-butyl ether (MTBE) by the hydrogen-oxidizing bacteriumHydrogenophaga flavaENV735 was evaluated. ENV735 grew slowly on MTBE ortert-butyl alcohol (TBA) as sole sources of carbon and energy, but growth on these substrates was greatly enhanced by the ad...... hiện toàn bộ
