Abstract

Methods and compositions for increasing a plant's resistance to an insect pest such as the corn rootworm are provided. Methods are provided for overexpression of Crw2, or variants thereof, in a host plant or plant cell to increase resistance to an insect pest in a plant such as maize. Methods are also provided for identifying variants of Crw2 that when incorporated into a plant via transgenic or traditional breeding means increase resistance to an insect pest in a plant such as maize. Also provided are methods for increasing resistance by overexpressing Crw1 and Crw2.

Abstract

The present invention is designed for use with a biolistic bombardment device having a cold gas shock wave splitter that divides a cold gas shock wave into two or more separate pressure waves that burst into one or more macrocarrier disks so as to create two or more separate microparticle groups. In various embodiments, the present invention provides a divider that is configured to define two or more separate bombardment areas, each configured to contain a respective target and to receive a separate one of the microparticle groups created by a cold gas shock wave splitter. In such a manner, the present invention avoids mixing of microparticles between microparticle groups and allows for independent biolistic bombardment of the targets.

Abstract

An acetyl xylan esterase variant having perhydrolytic activity is provided for producing peroxycarboxylic acids from carboxylic acid esters and a source of peroxygen. More specifically, a Thermotoga maritima acetyl xylan esterase gene was modified using error-prone PCR and site-directed mutagenesis to create an enzyme catalyst characterized by an increase in the ratio of peracetic acid formation to peracetic acid hydrolysis specific activities (PAAF/PAAH ratio). The variant acetyl xylan esterase may be used to produce peroxycarboxylic acids suitable for use in a variety of applications such as cleaning, disinfecting, sanitizing, bleaching, wood pulp processing, and paper pulp processing applications.

Abstract

A process is provided for rapidly producing target concentrations of peroxycarboxylic acids from carboxylic acid esters. More specifically, carboxylic acid esters are reacted with a source of peroxygen, such as hydrogen peroxide, in the presence of an enzyme catalyst comprising an enzyme having identity to an acetyl xylan esterase from Lactococcus lactis having perhydrolysis activity. The polypeptide is an enzyme structurally classified as a member of the carbohydrate esterase family 7 (CE-7). The peroxycarboxylic acids produced by the present process can be used in disinfecting, bleaching, and other laundry care applications. Compositions comprising the reaction components and the peroxycarboxylic acids produced by the process are also provided.

Abstract

Disclosed herein are two-component enzymatic peracid generation systems and methods of using such systems wherein the first component comprises a formulation of at least one enzyme catalyst having perhydrolysis activity, a carboxylic acid ester substrate, and a cosolvent and wherein the second component comprises a source of peroxygen in water. The two components are combined to produce an aqueous peracid formulation useful as, e.g., a disinfecting or bleaching agent. Specifically, organic cosolvents are used to control the viscosity of a substrate-containing component and to enhance the solubility of the substrate in an aqueous reaction formulation without causing substantial loss of perhydrolytic activity of the enzyme catalyst.

Abstract

A process for the synthesis of beta linked low molecular weight polymers of galactosamine and glucosamine has been developed. Through the use of high amounts of activating agents, efficient coupling of stable monomers is achieved. Using this process, chain extension is through the addition of single monomers, providing populations of single chain length polyhexosamines.

Abstract

A computer- implemented system and method for converting the resistances of an array of metal oxide sensors into constituents and concentrations of a multi-component gas provided around the sensor array. The method includes providing a self-diagnostic module to calculate the quality factors associated with corresponding prediction models and determine if the response of the sensor array are within a preferrred range; and providing a concentration calculation module to calculate the gas concentration outputs from each prediction model, corresponding tolerance limits, and gas concentration outputs determined by weighting the outputs from the prediction models by corresponding quality factors and determining the weighted tolerance limits, so that the gas concentration outputs with the lowest tolerance limits can be reported as the actual constituents and concentrations of the multi-component gas .

Abstract

Methods and compositions are provided for reducing the level of expression of a target polynucleotide in an organism. The methods and compositions selectively silence the target polynucleotide through the expression of a chimeric polynucleotide comprising the target for a sRNA (the trigger sequence) operably linked to a sequence corresponding to all or part of the gene or genes to be silenced. In this manner, the final target of silencing is an endogenous gene in the organism in which the chimeric polynucleotide is expressed. In a further embodiment, the miRNA target is that of a heterologous miRNA or siRNA, the latter of which is coexpressed in the cells at the appropriate developmental stage to provide silencing of the final target when and where desired. In a further embodiment, the final target may be a gene in a second organism, such as a plant pest, that feeds upon the organism containing the chimeric gene or genes. Compositions further comprise vectors, seeds, grain, cells, and organisms, including plants and plant cells, comprising the chimeric polynucleotide of the invention.

Abstract

A process for producing aqueous fluoropolymer dispersion with low fluorosurfactant content by polymerizing at least one fluoromonomer in an aqueous medium in the presence a fluorosurfactant to produce aqueous fluoropolymer dispersion having a first pH and an initial fluorosurfactant content. The process includes adding nonionic surfactant to stabilize the dispersion; contacting the stabilized fluorosurfactant-containing aqueous fluoropolymer dispersion with strong base anion exchange resin to reduce fluorosurfactant content to a predetermined level wherein the anion exchange resin is in the hydroxide form; and separating the anion exchange resin from the dispersion after the fluorosurfactant content has been reduced, the separated dispersion having a second pH. According to the invention, the first pH is sufficiently low such that an increase in pH resulting from the contacting with anion exchange resin produces a second pH less than a pH that promotes thermal degradation over volitilization of the nonionic surfactant in coating and film applications.

Abstract

A process for reducing the fluorosurfactant content of a stabilized fluorosurfactant-containing aqueous fluoropolymer dispersion by passing dispersion through a first fixed bed of anion exchange resin to reduce fluorosurfactant content. The first fixed bed has a working zone which moves though the column as the ion exchange resin is saturated. The process includes monitoring a property of the dispersion as the dispersion exits the fixed bed to determine break though of the working zone indicating saturation of the fixed bed. The property being monitored is selected from the group consisting of pH and conductivity.

Abstract

The present invention discloses a heat retentive food server for maintaining food at an elevated temperature, especially important in food service operations. The server is a container having an upper shell (15) and lower shell (20) and cavity (25) defined therebetween containing a phase change material (70) . The phase change material (70) is preferably an ethylene acrylate copolymer, which absorbs energy upon heating, and then keeps freshly prepared hot foods placed in the server warm as the phase change material slowly cools and releases heat.
