A peptide for synthesizing silica and use thereof are provided. The peptide for synthesizing silica can polymerize silica from a silica precursor in an aqueous solution having conditions of normal temperature, normal pressure and near-neutral weak base. The peptide for synthesizing silica can form a self-assembled structure during silica synthesis, and thus can be used as various biomaterials such as a silica-based protein immobilizer, a biosensor, and a drug delivery system.

摘要:
Mutant photosynthetic microorganisms having reduced chlorophyll and increased photosynthetic efficiency are provided. The mutants have a locked in high light-acclimated phenotype, in which many of the photosynthetic parameters characteristic of high light acclimated wild type cells are found in the LIHLA mutants when acclimated to low light, such as reduced chlorophyll, reduced NPQ, higher qP, higher Ek, higher P max per unit chlorophyll with little to no reduction in P max per cell, and higher rates of electron transport through photosystem II over a wide range of light intensities. Provided herein are constructs for attenuating or disrupting genes are provided for generating mutants having the LIHLA phenotype. Also provided are methods of culturing LIHLA mutants for the production of biomass or other products.
摘要:
The invention, in some aspects relates to compositions and methods for altering cell activity and function and the introduction and use of light-activated ion channels.
摘要:
The disclosure generally relates to methods and materials for modulating cell productivity. In particular, the present disclosure provides polynucleotides and polypeptides that when overexpressed in microorganisms result in increased in productivity, such as increased biomass productivity. Also disclosed are methods of using the polynucleotides and polypeptides to modulate or increase productivity of host cells such as, for example, algal or heterokont cells. Genetically engineered host cells, such as algal and heterokont cells having increased biomass productivity and bioproducts derived from such host cells are also disclosed.
摘要:
The present invention relates to a polypeptide (BIG1) and variants thereof capable of enhancing the rate of cell-division of a microorganism or plant cell, as well as nucleic acid molecules encoding said polypeptides, vectors comprising said nucleic acid molecules and host cells transformed or transfected with said vectors and expressing said polypeptides. The BIG1 polypeptide which has been identified in the marine centric diatom Thalassiosira pseudonana, variants thereof and nucleic acids encoding these may be used in methods of enhancing the rate of cell-division of microorganisms, plant cells or plants which produce useful sub stances or exhibit useful properties, to increase the yield thereof.
