Regulating polysaccharide synthesis in bacteria

Creator:: Chen, Donald D.
Resource Type:: Masters Thesis

Regulation of exopolysaccharide synthesis

Creator:: Dierksen, Karen P.
Abstract:: Lactococcus lactis subsp. cremoris Ropy 352 and L. lactis subsp. cremoris Hollandicus produce an exopolysaccharide (EPS) that imparts commercially desirable textural and rheological properties to fermented milk products. This ropy phenotype is expressed under specific environmental conditions. A mucoid EPS phenotype, also expressed under specific environmental conditions, but not involved...

Short lived bacterial regulatory proteins : what determines their fate?

Creator:: Ebel, Wolfgang, 1967-
Abstract:: Rapid degradation of certain short lived "timing" proteins is an effective mechanism for cells to control important regulatory pathways. The mechanisms by which regulatory proteases recognize their substrates are not well understood. Escherichia coli Lon, an energy dependent protease highly conserved in many prokaryotes and eukaryotes provides a model system...

Exopolysaccharide biosynthesis by a natural lactococcal ropy isolate

Creator:: Knoshaug, Eric P.
Abstract:: The genes coding for the expression of a ropy exopolysaccharide responsible for commercially desirable textural and rhealogical traits in fermented milk products by a natural lactococcal ropy isolate were sought. Using a transposon mutagenesis vector, pGh9:ISS1, three mutants lacking expression of the ropy exopolysaccharide were isolated. One of the mutants...

The discriminator domain : does it reside at the C-terminus or the N-terminus of Escherichia coli Lon?

Creator:: Miller, Darcey L.
Abstract:: The mechanisms of substrate recognition by regulatory proteases are not well understood. Presently, two opposing models have arisen to describe E. coil Lon's ability to discriminate between substrates: one suggests the N-terminus involvement while the second suggests the C-terminus involvement. In this project, the role of the C-terminal domain as...

Presence of Diarrhea and its Intensity due to Human Behaviors in Deh Sabz, Kabul, Afghanistan.

Creator:: Farhad, Mohammad
Abstract:: Afghanistan is one of the poorest countries in the world. Most of the people live in villages below the poverty line, and do not have access to basic health care and a primary education. Living standards are very low, and surviving day to day is a lifetime struggle. Most villages...
Resource Type:: Honors College Thesis

Chromatophores as cell-based biosensors for the detection of chemically and biologically toxic substances

Creator:: Dukovcic, Stephanie R.
Abstract:: Cell-based biosensors are function-based detectors that use the physiological response of a living cell to sense biologically stimulating agents. This emerging technology extends the application of current detection methods by reporting on the toxicity of a sample and the potential to cause disease. Previously, Betta splendens erythrophores have been described...
Resource Type:: Dissertation

Bacterial pathogens and associated toxins involved in erythrophore cell aggregation

Creator:: Hutchison, Janine R.
Abstract:: Current detection methods for bacterial contamination rely on structure based detection of proteins and nucleic acids. While these methods are easy to use and reliable, they cannot evaluate the toxicity of a sample and the potential to cause disease. Previously, erythrophore cells derived from Betta splendens had been suggested as...

Analysis of Betta splendens erythrophore responses to Bacillus cereus cultured in different media

Creator:: Austin, Melissa J.
Abstract:: Biological agents and their products commonly cause foodborne illnesses. In the United States it is estimated that there are over 76 million cases of foodborne illnesses each year, resulting in an economic loss of approximately $40 billion. These high figures demonstrate the need for bioassays that display a rapid and...
