    摘要: Embodiments provide a modified microbe capable of growing in or fermenting a solution, or lignocellulosic hydrolysate, comprising ferulic acid and/or coniferyl aldehyde. The microbe has one or more modifications to provide: (a) a decrease in copy number or expression of a BNA7 gene; (b) an increase in copy number or expression of one or more pentose phosphate pathway genes; and/or (c) localization of one or more products of the pentose phosphate pathway genes to the mitochondria or endoplasmic reticulum. Also provided is a microbe having modified expression or copy number of BNA7 and/or one or more of the pentose phosphate pathway genes. The pentose phosphate pathway genes may in certain embodiments be selected from at least one of ZWF1, TKL1, RPE1 and GND1. Also provided is a method for fermenting a substrate comprising ferulic acid and/or coniferyl aldehyde to produce a fermentation product.

    摘要: Provided herein are methods for removing mercury contaminant from an aqueous solution, the methods including: providing an aqueous solution, the aqueous solution being contaminated with at least trace amounts of an oxidized mercury species; culturing a photoheterotrophic or fermentative heterotrophic bacteria in the aqueous solution under anaerobic conditions in which the bacteria reduce the oxidized mercury species to elemental mercury (Hg0), wherein the bacteria comprises one or more bacteria of the order Clostridiales; and removing the elemental mercury from the aqueous solution. Also provided are bioreactors for removing mercury contaminant from an aqueous solution, as well as uses of photoheterotrophic or fermentative heterotrophic bacteria, wherein the bacteria comprises one or more bacteria of the order Clostridiales, for removing mercury contaminant from an aqueous solution.

    摘要: Described herein are uses of fluorescent enveloped virus particles as standards in nanoscale flow cytometry applications. The virus particles comprise a fluorescent dye or a fluorescent protein. A standard ladder comprising a plurality of fluorescent enveloped virus particles of different sizes is also provided. The standards may also comprise marker(s) of interest, and may be used as controls for detection of other viruses or extracellular vesicle, e.g. in diagnostic applications. Methods of producing controls for such applications are provided, including those having desired profiles. The controls may be used for enumeration of markers on microparticles (e.g. extracellular vesicles or viruses). Also described is a modified gammaretrovirus comprising a mutation that abolishes expression of the viral glyco-Gag protein, and having a fluorescent protein inserted in-frame into the proline-rich region (PRR) of the viral env protein. The gammaretrovirus may be M-MLV bearing a mutation that abolishes expression of the glyco-Gal protein, gPr80.

    摘要: Safety head wear for use for example in high risk activities such as sports and industrial purposes where protection from head injuries is required. Components are provided inserted between the liner and outer shell and consists of two parts; a chamber or bladder and a fluid or gel like material. The fluid or gel material is contained in the chamber or bladder and is positioned in such a way to create low friction between the surface of the shell and liner or liner and head. It can also be used on the outer surface of the shell or placed within two layers of the liner. The device provides a method of independently managing both compression and shear force characteristics of the helmet around the head designed to decrease brain trauma resulting from high linear and angular acceleration during impacts to the helmet.
