Whole-cell kinetics of trichloroethylene degradation by phenol hydroxylase in a Ralstonia eutropha JMP134 derivative
(American Society for Microbiology, 1998-11)
The rate, progress, and limits of trichloroethylene (TCE) degradation by Ralstonia eutropha AEK301/pYK3021 whole cells were examined in the absence of aromatic induction. At TCE concentrations up to 800 uM, degradation ...
High-temperature enzymatic breakdown of cellulose
(American Society for Microbiology, 2011-08)
Cellulose is an abundant and renewable biopolymer that can be used for biofuel generation; however, structural entrapment with other cell wall components hinders enzyme-substrate interactions, a key bottleneck for ethanol ...
Rickettsia parkeri and Candidatus Rickettsia andeanae in Amblyomma maculatum group ticks
(Centers for Disease Control and Prevention (CDC), 2020-02)
We determined prevalence of Rickettsia spp. in 172 ticks of the Amblyomma maculatum group collected from 16 urban sites in Oklahoma City, Oklahoma, USA, during 2017 and 2018. Most ticks (59.3%) were collected from 1 site; ...
Microplate fluorescence assay for measurement of the ability of strains of Listeria monocytogenes from meat and meat-processing plants to adhere to abiotic surfaces
(American Society for Microbiology, 2007-08)
Listeria monocytogenes is a significant food-borne pathogen that is capable of adhering to and producing biofilms on processing equipment, making it difficult to eliminate from meat-processing environments and allowing ...
Prevalence of Escherichia coli O157 in cattle feeds in Midwestern feedlots
(American Society for Microbiology, 2003-09)
Comparisons of enrichment methods (with or without antibiotics and with or without a preenrichment step) using gram-negative (GN) broth or tryptic soy broth (TSB) were conducted with feeds inoculated with Escherichia coli ...
New Mycobacterium avium antifolate shows synergistic effect when used in combination with dihydropteroate synthase inhibitors
(American Society for Microbiology, 2005-11)
Mycobacterium avium complex (MAC) is resistant to trimethoprim, an inhibitor of bacterial dihydrofolate reductase (DHFR). A previously identified selective inhibitor of MAC DHFR, SRI-8858, was shown to have synergistic ...
Influence of the drilling mud formulation process on the bacterial communities in thermogenic natural gas wells of the Barnett Shale
(American Society for Microbiology, 2011-07)
The Barnett Shale in north central Texas contains natural gas generated by high temperatures (120 to 150°C) during the Mississippian Period (300 to 350 million years ago). In spite of the thermogenic origin of this gas, ...
Identification of the inducing agent of the 2,4-dichlorophenoxyacetic acid pathway encoded by plasmid pJP4
(American Society for Microbiology, 1997-01)
The inducing agent of the 2,4-dichlorophenoxyacetic acid (2,4-D) pathway of Alcaligenes eutrophus JMP134 (pJP4) was determined through the analysis of promoterless lacZ transcriptional fusions with tfd structural genes. ...
Nutrients mediate intestinal bacteria-mucosal immune crosstalk
(Frontiers Media, 2018-01-24)
The intestine is the shared site of nutrient digestion, microbiota colonization and immune cell location and this geographic proximity contributes to a large extent to their interaction. The onset and development of a great ...
Influence of light on bacterioplankton production and respiration in a subtropical coral reef
(Inter Research, 1998-02-13)
The influence of sunlight on bacterioplankton production [14C-leucine (Leu) and 3H-thymidine (TdR) incorporation; changes in cell abundances] and O2 consumption was investigated in a shallow subtropical coral reef located ...
