β-lactoglubin adsorption equilibrium and kinetics at silanized silica surfaces

Creator:: Krisdhasima, Viwat
Abstract:: The adsorption equilibrium and kinetic behavior exhibited by β-lactoglobulin at silanized silicon surfaces of varying hydrophobicity were examined using ellipsometry. Adsorption equilibrium results were used to construct adsorption isotherms; the adsorbed mass of β-lactoglobulin was observed to increase with increasing surface hydrophobicity, within a defined range of hydrophobicity. Adsorption kinetics...

Studies on the hydrophobic effect and its contribution to the stability, crystallization, and helix packing of Z-DNA

Creator:: Kagawa, Todd F.
Abstract:: The studies presented here use the B- to Z-DNA transition and Z-DNA crystallization as model systems to determine the contribution of solvent interactions to macromolecular structures. The substituent groups of naturally occurring and modified nucleotide bases affect the hydration and thus the stability of right-handed B-DNA and left-handed Z-DNA. The...

Resistance of adsorbed nisin to exchange with bovine serum albumin, α-lactalbumin, β-lactoglobulin, and β-casein at silanized silica surfaces

Creator:: Muralidhara, Lakamraju
Abstract:: Nisin is an antibacterial peptide, which when adsorbed on a surface can inhibit bacterial adhesion and viability. The ability of noncovalently immobilized nisin to withstand exchange by the milk proteins bovine serum albumin, β-lactoglobulin, α-lactalbumin, and β-casein on surfaces that had been silanized with dichlorodiethylsilane to exhibit high and low...

Method development for characterizing the hydrophobicity of engineered nanoparticles

Creator:: Lee, Fang Yu
Abstract:: Characterizing the hydrophobicity of nanoparticles can help us understand their fate and transport in the environment, as well as how nanoparticles may interact with biological systems. However, contact angle and partition coefficient have limitations in measuring the hydrophobicity of nanoparticles, thus promising methods to measuring the hydrophobicity of nanoparticles are...

The influence of surface functional groups on β-lactoglobulin adsorption equilibrium

Creator:: Al-Makhlafi, Hamood K.
Abstract:: Interactions between proteins and contact surfaces can have important implications in the food industry. Such interactions contribute to the course of fouling of membrane surfaces and they appear to mediate bacterial and spore adhesion to some degree as well. In addition to protein and solution properties, interfacial behavior is strongly...

Bacterial hydrophobicity : assessment techniques, applications and extension to colloids

Creator:: Saini, Gaurav
Abstract:: This research details laboratory assessment of bacterial hydrophobicity, variations in bacterial adhesion properties with growth and extended starvation as well as extension of this assay to colloidal hydrophobicity measurement. Hydrophobicity is an integral component of surface interactions and has been studied extensively for its role in a number of engineering...

Exploring mechanisms that drive the development of reversible soil hydrophobicity

Creator:: Woolverton, Priscilla B.
Abstract:: This study focuses on one widespread characteristic of poor soil quality: hydrophobic soil. Previous research has produced conclusive evidence to show that soil hydrophobicity is affected by soil organic matter (SOM) and soil water content (WC). Hydrophobicity that responds to changes in WC is a unique form of surface hydrophobicity...

The influence of preadsorbed milk proteins on adhesion of Listeria monocytogenes to silica surfaces

Creator:: Al-Makhlafi, Hamood K.
Abstract:: β-lactoglobulin (β-Lg), bovine serum albumin (BSA), α-lactalbumin (α-Lac), and β-casein were adsorbed onto silanized silica surfaces of low and high hydrophobicity for 8 h, and β-Lg and BSA for 1 h. The surfaces were incubated in buffer for 0, 5, 10, or 15 h and then contacted with Listeria monocytogenes...

Surfactant interactions with recombinant factor VIII at the air/water interface

Creator:: Chu, Liping
Abstract:: The surface tension kin'ti4tnd ste'dy state behavior exhibited by mixtures of selected surfactants with a recombinant Factor VIII (rFVIII) were evaluated with automated interfacial tensiometry. In particular, fresh solutions of rFVIII with different concentrations of Tween 80, sodium dodecylsulfate (SDS), or dodecyltrimethylammonium bromide (DTAB) were prepared and their surface tension...

Effects of Initial Moisture and Surface Properties on Sorptivity of Coarse Soil and Sand

Creator:: Ambrowiak, Gloria M.
Abstract:: Many different models and mechanisms of water imbibition into soil have been described in the literature. Theoretical equations based on those models exist to predict how water will flow in porous media. These models can be useful, but have their weaknesses. Research on imbibition and infiltration into soils has mostly...
