(2013-07-24)Microbial-based industrial production has experienced a revolutionary development in the last decades as chemical industry has shifted its focus towards more sustain- able production of fuels, building blocks for materials, ...
-
(2017-07-31)Escherichia coli senses a variety of chemoeffectors. The Tsr chemoreceptor is known to mediate attractant response to serine. Previously, serine was the only attractant described for Tsr. Recent work suggests Tsr senses ...
-
(2013-05-02)Bacterial contamination due to excessive levels of bacteria is a confounding problem and remediation of impaired watersheds relies on the detection of fecal indicator bacteria and then assessing the source of said bacteria. ...
-
(2021-06-01)Low-molecular-mass (LMM) transition metal complexes are thought to play essential roles in metal ion trafficking, regulation, and signaling in biological systems. Their chemical identities remain largely unknown due to ...
-
(2018-05-09)Urban lotic surface waters have been extensively studied due to reported increases in their alkalization and dissolved organic carbon (DOC). However, urban lentic surface waters, which are subject to the same United States ...
-
(1993)E. coli cells expressing a recombinant organophosphate degrading gene (opd) were successfully encapsulated in polyvinyl alcohol (PVA) using cryoimmobilization. Gel matrices were composed of 10% cells in 10% PVA, and electron ...
-
(Texas A&M University, 2005-11-01)Toxic waste disposal problems have become enormous due to the proliferation of xenobiotic compounds for use in agricultural, industrial and numerous other applications. Organophosphate (OP) pesticides are commonly used in ...
-
(2013-01-04)This multi-phase project was designed (1) to evaluate existing post-harvest process controls and intervention strategies used to reduce Escherichia coli O157:H7, (2) to evaluate the impacts of cattle source and environmental ...
-
(2009-05-15)Antimicrobial interventions implemented in slaughter establishments for the reduction of enteric pathogens on beef carcasses must be validated to demonstrate efficacy under commercial operation conditions. Validation studies ...
-
(2015-11-18)Escherichia coli (E. coli) has a potassium (K+) channel (kch) and a non-selective ion channel (trkH/G). The goal of this project is to explore the individual function and modes of regulation for each system, which will ...
-
(2009-05-15)According to the USEPA National Section 303(d) List Fact Sheet, bacterial pathogens are the leading cause of water quality impairments in Texas. The automated Spatially Explicit Load Enrichment Calculation Tool (SELECT) ...
-
(2023-05-04)Escherichia albertii is an emerging foodborne enteropathogen. It was first isolated in 1991 from a 9-month-old febrile Bangladeshi girl with diarrhea, and retrospectively found to be the causative agent in a human foodborne ...
-
(2021-05-10)Bacteria have evolved to have different mechanisms of motility depending on the environment. On surfaces bacteria can locomote by swarming, a phenotype that is cell density dependent and requires cell coordination. As a ...
-
(2015-05-06)This study examines the relationship of E. coli concentrations and recreational use to both stream order and watershed size. To determine possible ecoregion effects, the E. coli data used in this study were obtained from ...
-
(2019-11-08)Shiga toxin producing E. coli (STEC) and Salmonella are two prominent bacteria that are recognized in pathogenic spread in the meat industry. In recent years outbreaks have occurred due to the ingestion of contaminated ...
-
(2016-12-06)Sections of streams located downstream from dairy farms and wastewater treatment plants (WWTPs) in central Texas are listed on the 303 (d) List of Impaired Waters due to bacterial contamination (possibly due to fecal ...
-
(2019-07-31)Pathogens are the leading cause of impairment for rivers and streams in the United States. Microbial contamination in recreational water bodies was the cause of 510 waterborne disease outbreaks in the United States. Water ...
-
(2014-08-12)Failing Onsite Wastewater Treatment Systems (OWTSs) have been identified as a significant threat to water quality, discharging significant amounts of inadequately treated sewage effluents. When developing a Watershed ...
-
(2012-10-19)When developing a Watershed Protection Plan (WPP) or a Total Maximum Daily Load (TMDL), it is often difficult to accurately assess the pollutant load for a watershed because not enough water quality monitoring data are ...
-
(2012-04-20)Ethylene is one of the most important and commonly used chemicals. Production of ethylene from a renewable resource would greatly reduce the amount of petroleum used in chemical processing. This would be a great help to ...
