Described herein are genelight cultures, extracts and related methods. 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.

A recombinant yeast cell that functionally expresses: a nucleic acid sequence encoding a protein having glycerol dehydrogenase activity; a nucleic acid sequence encoding a protein having dihydroxyacetone kinase activity; and a nucleic acid sequence encoding a protein having glycerol transporter activity, wherein the expression of the nucleic acid sequence encoding the protein having glycerol transporter activity is under control of a promoter (the GT promoter), which GT promoter has an anaerobic/aerobic expression ratio for the glycerol transporter of 2 or more, and a process for the production of ethanol using such recombinant yeast cell.

Provided are methods for plastid genome editing and development of plants, plant cells, plant parts, and seeds comprising edited plastid genomes. Compositions for transformation of plastid genomes are further provided. Specifically, the plastid genome is modified to comprise the replacement of a targeted endogenous plastid genome sequence with a modified version of the target plastid sequence, where the modified plastid genome sequence has been designed to deliberately reduce its homology to the targeted endogenous plastid genome sequence and, in some cases, encode a protein containing one or more mutations.
