摘要:Polyphosphate kinases (PPKs) for efficient regeneration of guanosine triphosphate (GTP) and use thereof are provided, belonging to the field of biotechnology. The PPKs expressed and obtained in Escherichia coli BL21(DE3) can efficiently regenerate the GTP using tripolyphosphate (tripolyP), tetrapolyP, and hexametaphosphate as phosphate donors. Use of the PPKs in regeneration of GTP as well as synthesis of guanosine diphosphate (GDP)-L-fucose or GDP-mannose and a derivative thereof (such as fucosyllactose) significantly improves synthesis sustainability and reduces a synthesis cost.

权利人:ECOLAB USA INC
摘要:This disclosure relates to capped block copolymers, preferably reverse block copolymers capped with a hydrophobic group. Preferred hydrophobic groups include benzyl groups and silyl groups. In a preferred embodiment, the reverse block copolymer has at least two arms, wherein each arm is capped with a hydrophobic group. The disclosure also provides for the synthesis of the capped block copolymers as well as methods of using the capped block copolymers for defoaming and antifoaming applications.

权利人:UNIV KANSAS STATE
摘要:A catalyzed synthesis of ascorbate 2-phosphorylated compounds is provided which gives both mono-and polyphosphorylated species in excellent yield using inexpensive, readily available reactants. The method involves forming a reaction mixture of an ascorbic acid reactant such as L-ascorbic acid and a metaphosphate phosphorylating agent (e.g., sodium trimetaphosphate), and carrying out the phosphorylation reaction in the presence of a catalyzing ion selected from the group consisiting of calcium, strontium and barium ion and mixtures thereof, while maintaining the pH of the reaction mixture at a level of from about 3-12. The synthesis is characterized by very short reaction times, preferably from about 15 minutes-2 hours, and moderate temperatures on the order of 18 DEG C.-25 DEG C. Preferably, the catalyzing ion is provided by addition of calcium, strontium or barium hydroxide to the reaction mixture, this serving to also elevate the pH of the system to the desired range.

摘要:An electrolysis unit ( 10 ) has an ion selective barrier ( 20 ) for separating an anodic chamber ( 12 ) from a cathodic chamber ( 14 ). An electrolyte within the unit includes a precursor, such as potassium acetate, or acetic acid. A positive potential is applied to an anode ( 16 ) within the anodic chamber, resulting in the generation of a variety of shorter and longer lived oxidizing species, such as peracetic acid, hydrogen peroxide, and ozone. In one preferred embodiment, a solution containing the oxidizing species is transported to a site where articles, such as medical instruments, are to be decontaminated. The oxidizing species are generated as needed, avoiding the need to store hazardous decontaminants.

摘要:Methods disclosed herein provide for an environmentally-friendly approach that employ citric extracts from fruits as unique reducing and stabilizing agents for making a tellurium nanomaterial. A particular method of making a tellurium nanomaterial includes combining citrus fruit extract with a tellurium salt to form a mixture of citrus fruit extract and dissolved tellurium salt; and heating the mixture of citrus fruit extract and dissolved tellurium salt, thereby making the tellurium nanomaterial. The resulting nanoparticles exhibit enhanced and desirable biomedical properties toward treatment of both infectious diseases and cancer.
