Algoland: Biological Solutions to Clean Air and Clean Water |
Interesting projects here. Cynobacteria reactors fed with cement plant CO2 and treated landfill wastewater to make biomass. Another is Actively cultivating small shell mussels/bivalves for ocean algae control and as a another biomass source.

An algal photoenzyme converts fatty acids to hydrocarbons | Science
GM bacteria using algae derived genes can convert fat to hydrocarbons using mostly (only?) blue light, by slicing off the carbon on a lipid chain with an enzyme

Horie-mon's new venture. Apparently commercializing a type of algae for biomass production for engineered nutrition, fibers, and biomass for biofuel production. Got the japanese government to bite, via NEDO. Now working with Isuzu for diesel substitute biofuels.

NASA - OMEGA Project
Interesting idea of feeding effluent/wastewater/sewage into ocean floating clear tubes to make algae and clean the water. End run around the issues of fertilizer/nutrient feeds for algae production, algae growth medium location, facility structure cost and location, and nicely deals with the wastewater output of sewage treatment facilities.

News releases 2012
Apparently, these guys were already working on using microbubbles to improves algae density in production. Now, they have retasked the same tech to help with floatation/separation/harvesting to ease gathering and drying, which is somewhat energy intensive normally. Naturally this assumes algae for biofuel where you are using the biomass directly (thus killing the algae), rather than using algae types the excrete oils that can be skimmed (and keep the algae alive).

Single-Step Extraction | OriginOil - Breakthrough Algae Oil Technology
Interesting take on the algae lipid recovery process, similar to GM algae that excrete oil, since both processes use a tank with surface skimming for recovery. Basically a wet recovery process that skips the drying process of conventional biomass lipid recovery. Still kills the little guys, but you would end up doing that if biomass was a production target anyways, but that introduces the issues of whether or not the energy costs of drying are transferred to the biomass or should be charged to the lipids, and there is a secondary concern of what sort of changes occur in the biomass, that could potentially make it unattractive as a product for specific industries (maybe pharmaceuticals/nutriceuticals might be out, but straight animal feed and biomass feedstock should be alright)

MSU News Service - MSU: Baking soda dramatically boosts oil production in algae
Interesting result, but they failed to do the simple check of seeing if simply bubbling CO2 gas through the algae grow medium fluid at the same critical timing would result in the same increase in performance. Specifically, is direct stimulation/fertilization of algae with carbon dioxide sufficient, or is the chemical pathway being used here specific to free swimming carbonate in solution.

Scientists look to ultrasound for control of blue-green algae
Interesting possible containment/filter method. I wonder if this could be applicable to algae farms, preventing hostile external species from invading systems, and preventing engineered species from escaping?

Fine-Tuning Growth Conditions Helps Cyanobacteria Flourish
Upping the phosphorus a bit means the limiters for growth are generally CO2 and light. Light you can do with tricky clear acryllic tubes and panels in novel arrangements. But the phosphorus is a problem. World supply is getting tighter due to industrial agriculture and runoff, so there is talk about peak phosphorus. Since we don't harvest sewage sludge and runoff for phosphorus, it gets trapped in sediment or washed out to sea. Most of the easy phosphorus sources are gone now.

Stanford researchers find electrical current stemming from plants
Directly tapping algae cells with piercing gold electrodes to siphon off photosynthesis electrons for power. Scalable? Probably not, unless you can culture the algae cells directly on an electrode grid panel and make them stick.

Potentially interesting closed photobioreactor technology using flat emitters for the lighting with good energy coupling to the algae. Only problem is, the website screams crank/scam, even if it isn't. Maybe a link to some whitepapers or published articles would be nice...

News Release : SHOWA DENKO K.K.
Someone pointed out that ideal plant growth acceleration under artificial lighting would be 92% red LED's and 8% blue LED's, and that white LED's are a waste of energy. So these special red LED's by SDK would be great for indoor agriculture and specialty photobioreactors for algae production.

Though there will be the inevitable comments about underground growops in a certain variant hemp industry...
