Disclosed herein are glucosyltransferases with modified amino acid sequences. Such engineered enzymes exhibit improved alpha-glucan product yields and/or lower leucrose yields, for example. Further disclosed are reactions and methods in which engineered glucosyltransferases are used to produce alpha-glucan.

Engineered glucosyltransferases

An oral care composition including a hydrophobic phase and a hydrophilic phase is disclosed. The hydrophobic phase may include a source of hydrogen peroxide and an acyl donor, and the hydrophilic phase may include an enzyme having perhydrolytic activity that catalyzes the generation of peracetic acid between the source of hydrogen peroxide and the acyl donor.

Oral care compositions and methods for increasing the stability of the same

An enzymatically produced soluble α-glucan fiber composition is provided suitable for use as a digestion resistant fiber in food and feed applications. The soluble α-glucan fiber composition can be blended with one or more additional food ingredients to produce fiber-containing compositions. Methods for the production and use of compositions comprising the soluble α-glucan fiber are also provided.

Enzymatic synthesis of soluble glucan fiber

An enzymatically produced α-glucan oligomer/polymer compositions is provided. The enzymatically produced α-glucan oligomer/polymers can be derivatized into α-glucan ether compounds. The α-glucan oligomers/polymers and the corresponding α-glucan ethers are cellulose and/or protease resistant, making them suitable for use in fabric care and laundry care applications. Methods for the production and use of the present compositions are also provided.

Glucan fiber compositions for use in laundry care and fabric care

A system for stimulating oil or gas production from a wellbore includes a hydraulic fracturing pump unit having one or more hydraulic fracturing pumps driven by one or more electrical fracturing motors, a variable frequency drive (VFD) controlling the electrical fracturing motors, a fracturing pump blower unit driven by a blower motor, and a fracturing pump lubrication unit having a lubrication pump driven by a lubrication motor and a cooling fan driven by a cooling motor. The system may further include a blender unit and a hydration unit. A system control unit may control the operational parameters of the system.

Well fracturing systems with electrical motors and methods of use

A dry product additive system includes a skid, a hopper, a pickup funnel, a feeder system, a supply pump, and an eductor assembly. The feeder system may be configured to transport product from the hopper to the pickup funnel. The eductor assembly including a suction inlet, a motive inlet, and an outlet. The suction inlet may be coupled to the pickup funnel by a suction hose. The motive inlet may be coupled to the supply pump by a motive fluid hose.

Dry product additive unit

An oral care composition, including a catalyzing enzyme and an anhydrous matrix configured to at least partially stabilize the catalyzing enzyme, wherein the anhydrous matrix includes a source of hydrogen peroxide, an acyl donor, a non-aqueous anhydrous liquid, and a surfactant mixture including sodium lauryl sulfate (SLS), Betaine, and a poloxamer.

Oral care compositions

An oral care kit comprising an oral care implement having a first reservoir containing a first oral care agent comprising a first whitening reagent that includes triacetin; and a container having a second reservoir containing a second oral care agent, the second oral care agent comprising a catalytic enzyme and a second whitening reagent that includes peroxide forming compound.

Whitening system

A method includes supplying a plurality of generators, each generator in electrical communication with a switchgear with each switchgear in data communication with a generator data management system. The method also includes supplying a plurality of electrically driven fracturing pumps with each electrically driven fracturing pump in data communication with pump data management system. Further, the method includes supplying a load shedding system, the load shedding system in data communication with the generator data management system and a pump control system, the pump control system in data communication with the pump data management system. The method includes determining which pumps should have speed reduced by the load shedding system and reducing the speed of the pumps determined by the load shedding system using the pump control system.

Wellsite electrical power management system

Disclosed herein are aqueous compositions comprising fructose and methods of production thereof. A method for producing an aqueous composition comprising fructose can comprise, for example, conducting an enzymatic reaction by contacting water, sucrose, and a glucosyltransferase enzyme that synthesizes poly alpha-1,3-glucan having at least 30% alpha-1,3-linkages. A soluble fraction produced by such a reaction comprises at least about 55% fructose on a dry weight basis, and can be separated from insoluble poly alpha-1,3-glucan product(s), thereby providing an aqueous composition comprising fructose.

Production and composition of fructose syrup

An enzymatically produced &#x3b1;-glucan oligomer/polymer compositions is provided. The enzymatically produced &#x3b1;-glucan oligomer/polymers can be derivatized into &#x3b1;-glucan ether compounds. The &#x3b1;-glucan oligomers/polymers and the corresponding &#x3b1;-glucan ethers are cellulose and/or protease resistant, making them suitable for use in fabric care and laundry care applications. Methods for the production and use of the present compositions are also provided.

A two-phase oral care whitening composition including a hydrophobic phase and a hydrophilic phase, and methods for oral care whitening teeth with the same are provided. The hydrophobic phase may include a source of hydrogen peroxide and an acyl donor. The hydrophilic phase may include an enzyme that catalyzes the generation of peracetic acid between the source of hydrogen peroxide and the acyl donor. At least one of the hydrophobic phase and the hydrophilic phase may further include at least one surfactant.
