Gracilaria Salicornia Oil Content

Do anyone know how much is the oil content of the ‘gracilaria salicornia’ algae?

Genetically Engineering Algae To Produce Bioplastics

Poly-3-hydroxybutyrate (PHB) is a thermoplastic polyester which can be found naturally in the bacteria: Bacillus megaterium and Ralstonia eutropha. The genes encoding for this polymer were identified and transferred to the algae Phaeodactylum tricornutum. This resulted in the synthesis and eventually accumulation of the compound in the cytosolic granules of the algae. When the researchers studied the algal biomass, the compound was found to constitute nearly 10 percent of the dry weight.

Covered Ponds

Covering ponds with translucent membranes or the use of greenhouses overcomes this problem, allowing the more productive strains to be grown free of atmospheric contamination.


In raceway ponds, large contaminants can be removed regularly by placing a suitably sized screen in the water flow. Heavy contaminants that sink to the bottom can be trapped in pits arranged at right angle to the flow and can then be removed from these sediment traps.

SCALING AND COMMERCIALIZATION OF ALGAE HARVESTING TECHNOLOGIES

The technology looks to efficiently remove algae from water potentially permitting the economic use of algae based products to be used for sustainable fuel, food, feed, chemicals, plastics and many more products and materials. 
This novel algae harvesting system could dramatically reduce the energy cost necessary to harvest, dewater, and dry algae and potentially transform the economics of algae-based biofuel production by removing a major barrier to large-scale commercialization.

Future Potential For Astaxanthin

Astaxanthin, as an anti-oxidant, has significant potential to increase the life-span…granted, it is expensive, but there are enough millionaires in the world (over 10 million millionaires), who can easily afford it!


Anyone has any idea of the future potential of astaxanthin? Right now, I believe it has a market of less than $300 million worldwide, which is surprising…

Could Be Competitive Algae Biofuel

Could be competitive algae biofuel production in relation to other methods?  If, yes, show it in numbers (not in many words), please. If, not now, explain why, please, also in figures. Especially when has appeared a new method of fossil fuel production: http://www.angelnexus.com/o/web/29729

How Can Algae Production Be Coupled With Anaerobic Digestion To Treat Wastewater?

Anaerobic digestion is a very effective process for BOD removal, but is not an effective way to remove nutrients. There is thus a need for further treatment of the effluent from anaerobic digesters before it can be discharged into the environment. And, this is where the algae based treatment comes in.

Quest and craze on algae but why has it not been commercialized yet?

I happened to come across an article where the commercialization of algae based fuels is under question. Despite the availability of algal strains, waste water and machinery, what are the constraints in commercialiing algae? The answer to which I understand is in getting the right algal strains, low energy harvesting processes and COST/ economics involved in a large scale production.


"On average so far algae production at the end of the process comes up with the ratio of water used to dry weight algae biomass of 1 to 0.01. With the amount of high energy usage during harvesting, you just cannot go commercial. The cost of adding phosphorous and nitrogen as well as concentrated CO2 throughout the algae growth would be enormous on a commercial scale. These are some of the most important factors preventing the move to commercial scale.

It seems so far no one has come up with a solution to these issues so the quest and craze on algae as a renewable energy source and other by products goes on. It is a long way off from providing the quantities of fuel to satisfy the current global demandeds at 1:0.01 ratio

The amount of energy produced from all biomass currently is about 1% or less of the total global energy usage."
