»Hydrogen from Algae
ξ hydrogen exists within certain algae
ξ if one can effectively manipulate those microorganism processes, one can capture solar energy directly in a form that is an ideal transportation fuel = LH2
ξ algal photosynthesis and hydrogen production are sister processes
ξ both start with the same solar-energy-activated splitting of water to oxygen, electrons, and protons;
ξ protons and electrons then go to a second enzymatic reaction
ξ in one case, the “normal” second reaction fixes carbon dioxide to produce sugar,
ξ in the other, an alternative reaction produces hydrogen molecules

~ Colorado Schools of Mines

»Colorado School of Mines
ξ the Environmental Science and Engineering Division (ESE) is a degree-granting academic program at the Colorado School of Mines (CSM)
ξ CSM is a institution with a focus on engineering and applied science related to earth, energy, materials and environment
ξ the current enrollment of 4,000 students includes those seeking B.S., M.S. and Ph.D. degrees
ξ the programs of study are interdisciplinary in scope
ξ faculty and staff are diverse in their backgrounds and expertise, spanning civil and environmental engineering, environmental chemistry,
ξ soil science, hydrology, ecology, microbiology, toxicology, and environmental law
ξ Robert L. Siegrist, Ph.D., P.E. Professor and Division Director, Email: siegrist@mines.edu

Environmental Biotechnology Laboratory
ξ houses current Division activities in the detection and manipulation of microbial genomes
ξ these efforts are directed toward understanding microbial activities in natural and engineered environments
ξ as well as modifying microbial activities to yield environmentally beneficial results in bioremediation and
ξ renewable energy (H2) production
ξ is equipped with thermocylers, protein and DNA electrophoresis apparatus,
ξ including DGGE apparatus, an autoclave, darkroom, transilluminator, ion chromatograph, laminar flow hood, and floor-scale and microcentrifuges
ξ in addition, an accessory room is equipped with a Leica confocal and epifluorescence microscope,

Basic Studies of Photosynthesis
ξ the process of plant photosynthesis produces the oxygen we breathe, the food we eat, and important materials for our houses, clothes, and industries
ξ in the future, it will also provide plant biomass for our fuel and
ξ more of our chemical needs through a process called "photoconversion"
ξ through photoconversion, these products will be renewable and non-polluting, and
ξ they won't contribute to global warming
ξ scientists in his group are working to understand the detailed mechanism of that part of the photosynthetic process associated with photosystem II,
ξ which provides the energy and reductant required by plants to grow
ξ this particular process uses sunlight to split water molecules and supplies us with oxygen (which to the plant is waste product)
ξ research has visualized the protein structure that performs these basic processes and
ξ has measured the extremely fast photochemical reactions (in trillionths of a second!) that drive these processes
ξ this understanding may someday help us improve the efficiency of natural photosynthesis and
ξ design artificial photosynthetic processes as next-generation systems to produce renewable energy

Algal BioHydrogen Research
ξ engaged in basic and applied research aimed at understanding the biochemistry and molecular biology of hydrogenases (algal biocatalysts that release H2 gas);
ξ the genomics and global metabolic pathways of the model organism, Chlamydomonas reinhardtii,
ξ that we have been using in BioHydrogen research; and
ξ processes and bioreactor systems in support of future algal, BioHydrogen-photoproduction system
