The present invention relates to materials comprising hydrophilic polymers and immobilized proteorhodopsin and the use of such materials as an optical information carrier. The material comprises one or more hydrophilic polymers that are capable to form a homogeneous phase with proteorhodopsin prior to solidification to a solid form. The hydrophilic polymer, for example, is silica sol-gel, gelatin, polyvinylalcohol, agarose, agar, methyl cellulose, polyvinyl acetate, polyvinyl pyrrolidone, polyethylene glycol, or a mixture thereof. The solid material having immobilized proteorhodopsin is deposited on a substrate selected from the group consisting of glass, paper, metal, fabric material, plastic material, and used as an optical data storage material or a fraud-proof carrier. The present invention further provides a security ink comprising proteorhodopsin and one or more hydrophilic polymers.

Assignee:
Genencor International, Inc. - Palo Alto CA
International Classification:
C12N 11/14 C12N 11/02 C12N 11/04
US Classification:
435176, 435177, 435182
Abstract:
This invention relates to a method of immobilizing biocatalysts including protein and cells by co-precipitation with silicate or organosilicate matrices through the action of an organic template molecule. The organic template molecule is in general a polyamine such as polyethylenimine (PEI), or polypeptide compound bearing at least two or three basic residues selected from the group consisting of lysine, arginine, histidine, proline, hydroxyproline, N-methylhistidine, ornithine, taurine, δ-hydroxylysine, and δ-hydroxy-ω-N,N,N trimethyllysine. The invention is also directed to a silica biocomposite comprising co-precipitates of active biocatalysts, silica or organosilicates, and an N-containing organic template molecule. Such silica biocomposites are useful in biocatalysis, and other applications requiring an immobilized biocatalyst. Preferred biocatalysts for this invention are enzymes and whole cells.

US Classification:
8107, 8102, 8111, 8115, 811561, 8181, 8192
Abstract:
Novel laccase mediators, including carboxyamido and cyano derivatives of 2,6-dimethoxyphenol that exhibit improved hydrolytic stability and good bleaching performance. The novel laccase enzymes may be employed in conjunction with the 2,6-dimethoxyphenol derivatives of this invention to provide an improved method for bleaching denim fabrics.

International Classification:
C12P 5/02 C07C 11/10
US Classification:
435167, 585 16
Abstract:
The invention features methods for producing isoprene from cultured cells wherein the cells in the stationary phase. The invention also provides compositions that include these cultured cells and/or increased amount of isoprene. The invention also provides for systems that include a non-flammable concentration of isoprene in the gas phase. Additionally, the invention provides isoprene compositions, such as compositions with increased amount of isoprene or increased purity.
