Title: Method for producing hydrogen and oxygen by use of algae

Full Record
Other Related Research

Abstract

Efficiency of process for producing H.sub.2 by subjecting algae in an aqueous phase to light irradiation is increased by culturing algae which has been bleached during a first period of irradiation in a culture medium in an aerobic atmosphere until it has regained color and then subjecting this algae to a second period of irradiation wherein hydrogen is produced at an enhanced rate.

Method to transform algae, materials therefor, and products produced thereby

Patent Dunahay, Terri Goodman [2710 Arbor Glen Pl., Boulder, CO 80304]; Roessler, Paul G [15905 Ellsworth Pl., Golden, CO 80401]; Jarvis, Eric E [3720 Smuggler Pl., Boulder, CO 80303]

Disclosed is a method to transform chlorophyll C-containing algae which includes introducing a recombinant molecule comprising a nucleic acid molecule encoding a dominant selectable marker operatively linked to an algal regulatory control sequence into a chlorophyll C-containing alga in such a manner that the marker is produced by the alga. In a preferred embodiment the algal regulatory control sequence is derived from a diatom and preferably Cyclotella cryptica. Also disclosed is a chimeric molecule having one or more regulatory control sequences derived from one or more chlorophyll C-containing algae operatively linked to a nucleic acid molecule encoding a selectable marker,more » « less

Method and system for producing hydrogen using sodium ion separation membranes

Patent Bingham, Dennis N; Klingler, Kerry M; Turner, Terry D; ...

A method of producing hydrogen from sodium hydroxide and water is disclosed. The method comprises separating sodium from a first aqueous sodium hydroxide stream in a sodium ion separator, feeding the sodium produced in the sodium ion separator to a sodium reactor, reacting the sodium in the sodium reactor with water, and producing a second aqueous sodium hydroxide stream and hydrogen. The method may also comprise reusing the second aqueous sodium hydroxide stream by combining the second aqueous sodium hydroxide stream with the first aqueous sodium hydroxide stream. A system of producing hydrogen is also disclosed.

Methods for producing hydrogen using nanoparticle-catalyst mixtures

Patent Krauss, Todd D.; Eisenberg, Richard; Holland, Patrick; ...

Provided are compositions for and methods of producing hydrogen. For example, the compositions comprise nanocrystals, a catalyst, a source of electrons, and an aqueous medium. The nanocrystals, catalyst, aqueous medium, and, optionally, the source of electrons are present as a mixture. The methods produce hydrogen by exposing the compositions to electromagnetic radiation (e.g., solar flux).

Method for delivery of small molecules and proteins across the cell wall of algae using molecular transporters

Patent Geihe, Erika; Trantow, Brian; Wender, Paul; ...

The introduction of tools to study, control or expand the inner-workings of algae has been slow to develop. Provided are embodiments of a molecular method based on guanidinium-rich molecular transporters (GR-MoTrs) for bringing molecular cargos into algal cells. The methods of the disclosure have been shown to work in wild-type algae that have an intact cell wall. Developed using Chlamydomonas reinhardtii, this method is also successful with less studied algae, including Neochloris oleoabundans and Scenedesmus dimorphus, thus providing a new and versatile tool for algal research and modification. The method of delivering a cargo compound to an algal cell comprisesmore » « less
