Antimicrobial peracid compositions with selected catalase enzymes and methods of use in aseptic packaging

Abstract: The present invention relates to specially selected catalase enzymes and their use in reducing hydrogen peroxide in applications, and particularly in aseptic packaging applications.

Zero phosphate warewashing detergent composition

Abstract: A warewashing detergent composition with an improved builder system having zero phosphate that conditions service water by holding or suspending divalent or trivalent hardness ions in solution and by preventing precipitation of the hardness ions beyond their stoichiometric concentration. The composition comprises a source of alkalinity, a water-conditioning vinyl polymer with pendant --CO 2 H groups, a soil-dispersing phosphinopolycarboxylic acid, and a water-conditioning organic phosphonate.

Stable carbon isotope evidence for nitrogenous fertilizer impact on carbonate weathering in a small agricultural watershed.

Abstract: The isotopic signature of Dissolved Inorganic Carbon (DIC), δ13CDIC, has been investigated in the surface waters of a small agricultural catchment on calcareous substratum, Montousse, located at Aurade (south‐west France) The Montousse catchment is subjected to intense farming (wheat/sunflower rotation) and a moderated application of nitrogenous fertilizers During the nitrification of the NH4 +, supplied by fertilization, nitrate and H+ ions are produced in the soil This anthropogenic acidity is combined with the natural acidity due to carbonic acid in weathering processes From an isotopic point of view, with ’natural weathering’, using carbonic acid, δ13CDIC is intermediate between the δ13C of soil CO2 produced by organic matter oxidation and that of the carbonate rocks, while it has the same value as the carbonates when carbonic acid is substituted by another acid like nitric acid derived from nitrogen fertilizer The δ13CDIC values range from −171‰ to −107‰ in Montousse stream waters We also measured the δ13C of calcareous molassic deposits (average −79‰) and of soil organic carbon (between −241‰ and −26‰) to identify the different sources of DIC and to estimate their contribution The δ13CDIC value indicates that weathering largely follows the carbonic acid pathway at the springs (sources of the stream) At the outlet of the basin, H+ ions, produced during the nitrification of N‐fertilizer, also contribute to weathering, especially during flood events This result is illustrated by the relationship between δ13CDIC and the molar ratio NO3 –/(Ca2+ + Mg2+) Consequently, when the contribution of nitrate increases, the δ13CDIC increases towards the calcareous end‐member This new isotopic result provides evidence for the direct influence of nitrogen fertilizer inputs on weathering, CO2 consumption and base cation leaching and confirms previous results obtained using the chemistry of the major ions present in the field, and in soil column experiments

Simultaneous use of peroxygen and olefin compound in odor reduction

Abstract: Disclosed is a process for the treatment of a plant fluid effluent containing odor compounds including an alkyl mercaptan or an alkyl thiol, an amine compound, ammonia, hydrogen sulfide and mixtures thereof by contacting the plant effluent in either a counterflow or cocurrent flow process. In the process, the effluent is contacted with an aqueous solution comprising a peroxyacid compound and one or more essential oils. When contacted with the peroxyacid, odor compounds in the effluent are oxidized and converted from the gaseous phase into a chemically modified highly aqueous soluble phase in the aqueous treatment. In this way, odor removal from the gas is preferred and odor compounds are efficiently transferred into the aqueous treatment solution. The use of such a process produces a significant improvement in odor quality index as measured by a conventional process using an expert panel when compared to conventional treatment methods.

Liquid fabric conditioner composition and method of use

Abstract: The invention includes a method of conditioning fabrics, comprising contacting fabric with a liquid composition comprising an amino-functional silicone and a quaternary ammonium, and drying said fabric at 200 degrees F. or greater. The invention includes a method of conditioning fabrics, comprising washing fabric in a detergent having a wash pH of greater than 10, contacting fabric with a liquid composition comprising an amino-functional silicone and a quaternary ammonium, and drying said fabric at less than 200 degrees F. The invention further provides a method of conditioning fabrics wherein softness, anti-static, and anti-wrinkle properties are imparted to the fabric wherein the conditioned fabric resists yellowing in industrial and institutional conditions wherein the wash pH is greater than 9 and/or the fabric temperature is 200 degrees Fahrenheit or greater.
