(Texas A&M University. Libraries, 1986)Genes and gene products in the transfer region of the Escherichia coli plasmid F were investigated. A detailed restriction map of F DNA in the traB-traG region was constructed, and a series of plasmids expressing SmaI, ...
-
(Texas A&M University. Libraries, 1986)Bacteriophage Mu dl(lac,Ap[superscript r]), a transposable element, was used to inactivate the pyrB gene by insertion. Derivatives of these pyrimidine auxotrophs were used to select the pyrB gene cloned pBR322. Three ...
-
(Texas A&M University, 2006-10-30)Autoinducer 2 (AI-2) is a quorum sensing signal employed by bacteria to coordinate their response to environmental stresses. The objective of this study was to determine the relationship between presence of AI-2 molecules, ...
-
(1990)The Asp15-->Ala mutant of ribonuclease T1 (RNase T1) was constructed by site-directed mutagenesis, cloned and expressed in Escherichia coli. This mutant was synthesized to determine whether or not the aspartic acid at ...
-
(2020-04-16)Strain robustness and productivity are key traits for bio-based production. Stressors, such as inhibitory compounds present in the feedstock, osmotic, temperature, and toxic products, can inhibit cell growth and productivity. ...
-
(2019-11-01)K^+ channels are widely conserved among all species. Although bacterial K^+ channels are often used in structural and biophysical assays as models for their eukaryotic homologs, little is known about their physiological ...
-
(Texas A&M University. Libraries, 1991)The Escherichia coli Rep protein has DNA-dependent ATPase activity and unwinds duplex DNA with an apparent 3' to 5' directionality. Biochemical and biophysical aspects of the Rep helicase-DNA interactions were examined in ...
-
(Texas A&M University. Libraries, 1987)The ATCase from Escherichia coli has been the subject of extensive physical, biochemical and genetic studies. The exact natures of the intrasubunit and intersubunit interactions responsible for enzymatic function are still ...
-
(2012-12-03)The Escherichia coli twin-arginine translocation (Tat) system transports fully folded and assembled proteins across the inner membrane into the periplasmic space. The E. coli Tat machinery minimally consists of three ...
-
(2015-11-12)Mastitis is the number one infectious disease on dairies. Treatment and prevention is mainly through good milking hygiene, proper environmental conditions, and antibiotic usage. For organic dairies, mastitis prevention and ...
-
(Texas A&M University. Libraries, 1976)Resistance to the proline analogue, azetidine-2-carboxylic acid, was used as a selection technique with E. coli in order to measure the production of mutations caused by low doses of X-radiation. An improved procedure was ...
-
(2021-01-20)Functional characterization of metagenomic DNA often involves expressing heterologous DNA into genetically tractable microorganisms such as Escherichia coli. Expression of heterologous genes can suffer from limitations due ...
-
(2013-11-15)In the United States, the proportion of outbreaks of microbial foodborne illnesses associated with fresh produce has increased over the past decades. A large proportion of these outbreaks have been caused by enteric ...
-
(2012-02-14)Escherichia coli is the best characterized bacterium; it grows rapidly, and it is easy to manipulate genetically. An increased knowledge about the physiology of this model organism will facilitate the development of ...
-
(2015-12-01)Non-O157 Shiga-toxin producing Escherichia coli (STECs) serovars O145:NM, O45:H2, O26:H11, O103:H11, O111 (organism was originally ordered from American Type Culture Collection (ATCC) under accession # BAA-2217, and has ...
-
(2018-10-24)Scientists are slowly gaining a better understanding of the composition of the gut microbiota and the role it plays in maintaining metabolic homeostasis in the host. Metagenomic sequencing of various gut microbial species ...
-
(2012-10-19)The purpose of this dissertation is threefold: to determine the differences in apparent prevalence and the antimicrobial susceptibility of Campylobacter spp. between antimicrobial-free and conventional swine farms; secondly, ...
-
(2017-07-27)Industrial biotechnology provides a sustainable and environmentally sound way to produce chemicals by using renewable raw materials. Sustainability of industrial biotechnology can be further improved if alternative water ...
-
(1990)Bacteria swim through their environment, but not that much is known about the "motor" which propels them. In Escherichia coli, a bacteria found in human intestines, six to eight flagella(4) move the cell around so that it ...
-
(Texas A&M University. Libraries, 1976)Orotidine 5'-monophosphate decarboxylase has been partially purified approximately 200-fold from Escherichia coli. The molecular weight determined by gel filtration was 56,000. The enzyme exhibited biphasic kinetics. A new ...
