The present disclosure provides mammalian cell lines for expression of viral vectors, and methods of making and using the same. Provided methods employ use of identifiers that are capable of being packaged into a viral vector to select and/or identify mammalian cell lines with engineered sequences associated with beneficial characteristics for viral vectors production. Exemplary viral vectors include AAV vectors.

Mammalian cells and methods for engineering the same

A method for removal of sulfide from a stream, the method comprising preparing a metal-chelant complex, designated M-Yn, where M is a divalent or trivalent cation, Y comprises a gluconic acid, glucaric acid or derivative thereof, and n is from about 1 to about 3; contacting a mixture comprising M-Yn and a base with a sulfide stream under conditions suitable for the formation of a metal-sulfide species; and contacting the metal-sulfide species with an oxidizing agent to form a soluble metal sulfide species. A method for removal of sulfide from a stream, the method comprising preparing a sulfide scavenging mixture comprising a base and a metal-complex characterized by Structure (I); contacting the sulfide scavenging mixture with a sulfide stream under conditions suitable for the formation of a metal-sulfide species; and contacting the metal-sulfide species with an oxidizing agent to form a soluble metal sulfide species.

A hydrogen peroxide and gluconic acid production method and system is disclosed that can include receiving an aqueous solution having glucose, water, and glucose oxidase at a reaction chamber. Here, the reaction chamber facilitates an enzymatic reaction between a gas phase and a liquid phase of the aqueous solution, thereby yielding a first solution comprising hydrogen peroxide, gluconic acid, and the glucose oxidase. The method can further include receiving the first solution at a separation chamber, wherein the separation chamber is comprised of a semi-permeable membrane having a pre-defined molecular weight barrier for separating the glucose oxidase, thereby resulting in a combined hydrogen peroxide and gluconic acid solution. The method can further include at least partially converting the gluconic acid into a gluconate salt, and separating and concentrating the hydrogen peroxide from the gluconic acid or gluconate salt via vacuum flash evaporation and vacuum distillation.

Hydrogen peroxide and gluconic acid production

A hydrogen peroxide production method, system, and apparatus is provided for producing large volumes of hydrogen peroxide having concentrations up to and excess of 80% in one continuous cycle. In one aspect, the hydrogen peroxide production system can include an aqueous solution comprised of an NQO1 enzyme, an NQO1 activated compound or molecule, and an NADH or NADPH cofactor for producing hydrogen peroxide, a production chamber having a semi-permeable membrane for receiving the aqueous solution. Here, the membrane can further include one or more molecular weight barriers configured to diffuse the produced hydrogen peroxide there through. The system can also include a collection chamber for receiving the produced hydrogen peroxide, and one or more pumps for circulating the aqueous solution having the hydrogen peroxide to the collection chamber and back to the production chamber.

A hydrogen peroxide production method, system, and apparatus is provided for producing large volumes of hydrogen peroxide having concentrations up to and excess of 80% in one continuous cycle. In one aspect, the method can include mixing NQO1 enzyme, an NQO1 activated compound or molecule, and an NADH or NADPH cofactor with an aqueous solution, dispensing the aqueous solution within or onto a semi-permeable membrane, wherein the semi-permeable membrane further includes a pre-defined molecular weight barrier. In addition, an oxidation-reduction reaction of the NQO1 enzyme, the NQO1 activated compound or molecule, and the NADH or NADPH cofactor within the aqueous solution produce hydrogen peroxide at a concentration level. Here, the produced hydrogen peroxide is above the pre-defined molecular weight barrier of the semi-permeable membrane and diffuses through the semi-permeable membrane to be extracted for use.
