Fuente: WIPO "tomato" Described herein are genelight cultures and extracts and methods of making and using thereof. In one aspect, the method of making a genelight culture or extract includes the steps of (a) making a DNA construct containing genes for producing a heat shock protein, RuBisCO large subunit 1, tonB, hydrogenase, and a P-type ATPase, (b) introducing the DNA construct into host microbial cells via transformation or transfection, and (c) culturing the microbial cells to produce the genelight cultures and extracts. The compositions of these cultures and extracts can be tailored to have specific properties such as the ability to provide power to a light emitting diode. The cultures and extracts have further uses including enhancing the growth of plants and as supplemental nutrients of cultures of industrially important microorganisms. The cultures and extracts further have UV-protective properties. Also described herein are microbial electric circuits containing the cultures and extracts described herein.
