What I can say is, that light is very important factor of any fuge that grows macro algae. Search for:. The failure to change metabolism owing to environmentally adverse conditions may be disadvantageous for survival in a competitive environment; however, impeding these pathways may allow for more consistent yields in partially controlled environments [ ], such as those being considered for algal biofuel production. Once extracted, because crude algae oil is chemically similar to crude fossil fuel oil, the engineering challenges associated with algae oil conversion to usable liquid fuels are similar to those already well managed by petroleum companies, although improved catalysts will be required to improve gasoline production from bio-oil [ 31 ]. Harmful Algal Bloom Forecasts. Food Sci.

Plant Cell 29, — Simply put it anywhere in your system, give it light strong enough to grow nuisance algae and it should be easy to keep. Comment by eileenroffe posted on on 30 July A number of algal species can be induced to produce hydrogen gas using the reducing potential of photosynthesis in a reaction catalyzed by a hydrogenase [ ]; however, both the movement towards a hydrogen economy and the ability to engineer algal species to produce substantial amounts of hydrogen in a regulated manner have moved forward at a slower rate than once predicted.

Our model consists of seven major factors: 1 annual maintenance costs: this includes personnel, land taxes, fertilizer costs, upkeep, water and power; 2 harvesting costs: this cost is incurred every time algae reaches harvesting stage which is a function of growth rate, and maximum growth density it includes costs for water extraction, oil extraction and oil transport from harvest site to sales destination ; 3 pond depth: this is how deep the ponds can be made while the algae still maintain optimal growth rates. While crop plants have been bred and selected for millennia to isolate specific traits and to obtain highly productive strains, all present microalgal species are effectively environmental isolates.
