Abstract: An electrostatic sprayer includes a spray gun having a nozzle at which pressurized spray media and pressurized air are combined into an atomized mixture. A generator electrostatically charges the atomized mixture at the nozzle. The generator may also electrostatically charge the pressurized spray media, or the pressurized air, or both at the nozzle. An input device of the spray gun is actuable by a user to vary a flow of the pressurized spray media to the nozzle. A main unit is connected to the spray gun with a hose via which the pressurized spray media and the pressurized air are communicated to the spray gun. The main unit has a first power mode in which a battery powers component(s) of the electrostatic sprayer. The main unit also has a second power mode in which a power source spaced apart from the main unit powers the component(s) of the electrostatic sprayer.

Abstract: A process for producing high yields of enantioselective amino acids and chiral amines by reacting a keto acid or ketone and an amino acid donor in the presence of a transaminase biocatalyst to produce a keto acid by-product and an amino acid or amine product. Further reacting the keto acid by-product with a peroxide to increase the yield of additional amino acid or amine product.

Abstract: A method for detecting biofuel producing microbes in a colorimetric assay by providing a microbe, a feedstock, and an assay solution. The assay solution contains an alcohol oxidase, a peroxidase, and a peroxidase co-substrate. The microbe is cultured with the feedstock as part of a culture medium that produces a detectable amount of bioalcohol. The culture medium is contacted with the assay solution to produce a colorimetric reaction to screen for a biofuel producing microbe.
