(2017-07-31)This project was designed to validate antimicrobial applications on intact beef subprimals, frozen beef, and moisture-enhanced beef for the reduction of Shiga toxinproducing Escherichia coli (STEC). In-plant validation ...
-
(2012-10-19)Excessive bacterial levels are a major water quality concern. Better methods are needed to quantify the proportion of bacterial loading contributed by various sources, and best management practices are needed to restore ...
-
(2011-02-22)Carters Creek in Brazos County, Texas, like many surface water reaches in the Texas Gulf Coast region, has been identified for bacteria and nutrient impairment on the Texas Commission on Environmental Quality (TCEQ) 303(d) ...
-
(2013-08-28)Numerous outbreaks of foodborne illness have been attributed to non-intact beef (e.g., tenderized, marinated, and enhanced) products contaminated with Escherichia coli O157:H7. Organic acids are commonly utilized in the ...
-
(2009-05-15)Autoinducer 2 (AI-2) molecules produced by bacterial cells are thought to be involved in controlling a variety of bacterial cellular processes by coordinated gene and protein expression. Previous work in our laboratory has ...
-
(2016-04-26)E. coli contamination in surface waters is a universal issue that signifies increased risks to human health. Understanding E. coli fate, transport, sources, and distribution in watersheds is critical for reducing these ...
-
(2012-10-19)There are approximately 10^14 bacteria belonging to nearly 1000 different species in the human gastrointestinal (GI) tract that co-exist with host cells. Within the GI tract, signaling molecules secreted by both eukaryotic ...
-
(2021-08-31)Bacterial chemotaxis to microbial-derived metabolites likely plays a key role in shaping the diversity in microbial communities in the gastrointestinal tract (GI tract). Among the important metabolites is indole, which ...
-
(2012-10-15)This study evaluated methods for controlling Escherichia coli O157:H7 and Salmonella non-pathogenic bacterial surrogates during the production of marinated non-intact beef products. Hot (~30 degrees C) boneless, beef strip ...
-
(2013-12-12)Foodborne illness outbreaks associated with fresh produce have increased over the past decade. Food workers employed at full-service restaurants are found to perform risky food practices more often than food workers ...
-
(Texas A&M University, 2005-02-17)Phosphofructokinase from Escherichia coli (EcPFK) is allosterically regulated by MgADP and phospho(enol)pyruvate (PEP). Both molecules compete for binding to the same allosteric site, however, MgADP activates and PEP ...
-
(2014-07-24)Since 1996, the E. coli levels in Dickinson Bayou have been considerably higher than the Texas state maximum of 126 colony forming units (CFU) per 100 mL for recreational waters. One hypothesis is that failing onsite sewage ...
-
(2021-10-20)Dwindling supplies of readily available freshwater, coupled with the continuous growth of the human population, necessitates the purification and reuse of wastewater. This requires next-generation treatment processes, such ...
-
(2017-12-01)Cellular decision making is a ubiquitous process among all life forms, and a key step that organisms take to integrate the environmental signals to choose an optimal response to improve their overall fitness. The genetic ...
-
(2021-11-30)The excursion into biological iron-sulfur cluster assembly began at the close of the 20th century, and has continued to develop in the last twenty years. Currently, it is known that [2Fe-2S] clusters are assembled through ...
-
(2018-11-08)Section 303(d) of the Federal Clean Water Act cites bacterial pathogens as one of the most common cause of impairment in the streams and other water bodies in the state of Texas and the number of bacteria impaired water ...
-
(1989)Aspartate transcarbamoylase (ATCase, EC 2.1.3.2) is a ubiquitous enzyme which catalyzes the first unique step in pyrimidine biosynthesis in both prokaryotes and eukaryotes. From bacteria to animals, enzyme complexes occur ...
-
(2012-11-28)Thiamin transport in Escherichia coli is a model system to establish the tolerance of derivatives for transport into the cell. Since little is known about what types of thiamin derivatives may be successfully taken into ...
-
(2013-12-09)Reactivation of different Escherichia coli strains and Aeromonas hydrophila after ultraviolet (UV), ultrasound, and photocatalytic disinfection treatments was addressed in this study. Photocatalytic disinfection was carried ...
-
(2021-05-12)Escherichia coli swarm on semi-solid agar surfaces with the aid of flagella. One hypothesis suggests swarmer cells may overcome the increased viscous drag near surfaces by developing higher flagellar thrust and by promoting ...
