  • why in nutrient deficient environment algae produces more lipid?

    in Algae Fuels

    • Gaya3 4 years ago

      Under nutrient deficient conditions , Biochemical studies have also suggested that acetyl-CoA carboxylase (ACCase), a biotin-containing enzyme that catalyzes an early step in fatty acid biosynthesis, may be involved in the control of this lipid accumulation process.

  • Hi there, what is the metal ion which have toxic effect on microalgae? or what is the heavy metals that affecting algal growth?

    in Biomass Power Production Algae Fuels

    • Gaya3 4 years ago

      Generally the order of metal toxicity which affects the algal species is Hg> Cu>Cd>Ag>Pb>Zn. Mercury being the most toxic metal affects the enzyme systems of the algae and inhibits their functions. Copper is used to control the algal blooms in fresh water. The extent of toxicity depends on the ionic content or free Cu2+ ions available in the algal culture and not the total copper concentration.

  • 2 weeks ago there was a big news about Solazyme selling Algae Biodiesel and after that, I couldnt find any news article on the same. I would like to get an update on present status and user feedback from people who have used 20% algae fuel blend. Pls let me know if you come across any article on this.

  • This was what I read earlier today:"As of this week, a diesel fuel mix of 20% algae and 80% petroleum is available at four gas stations in Redwood City, San Jose, Berkeley, and Oakland. Drivers can fill up at designated Propel Clean Fuel Points (alternative fuel stations often located inside traditional gas stations). The algae comes from Solazyme, a renewable algae oil company that is also making inroads in the cosmetics and food industries.

    In addition to just cutting down on petroleum use, Solazyme claims that its fuel, which reportedly costs just under $4.25 per gallon (the average diesel fuel price in the Bay Area) at the Redwood City location, reduces particulate by 30%, CO2 by 20%, and total hydrocarbon emissions by 10%."

    Can some one find out if this is yet another nice PR spin or if Solazyme has become the first company in the world to find the "secret sauce" that can make cheap algae oil commercially? If I remember right, they use sugar as the base for heterotrophic growth...dunno if they still follow the same concept...

  • Does anyone know any other "cleantech" sites that pick up news on the innovation front, news on science behind algae or other sources with information i can take a look on? Feels like cleantech is a bit dead for a 18 year old dude like myself =)

      We have a section at CleanTick called CleanTick Feeds, where we automatically get blog post feeds from over 100 popular cleantech blogs http://www.cleantick.com/feeds Many of the blogs here could be of use to you, not to mention the aggregated feeds themselves

  • I really want to run some experiments growing algae heterotrophically or maybe mixotrophically. I have heard that cell densities as well as lipid content can get to very high levels. But I am having trouble finding good literature [technical or otherwise] to base experiments from. Could someone please help me out, or at least point me in the right direction

  • The number of companies developing algal biofuels has been increasing, and several oil companies are investing in them. Given these and other interests, the National Research Council was asked to identify sustainability issues associated with large-scale development of algal biofuels. A NRC report released on yesterday reveals certain issues in Algae fuels. The following are some of the key statements in the report:

    1. To produce 39 billion liters of algae based biofuel, roughly six to 15 million metric tons of nitrogen and nearly 1 to 2 million metric tons of phosphorus would be needed if the nutrients are not recycled.

    2. The committee found that to produce the amount of algal biofuel equivalent to 1 liter of gasoline, between 3.15 liters to 3,650 liters of freshwater is required, depending on the production pathway.

    Here is the link to the report - http://www.nap.edu/openbook.php?record_id=13437&page=1

      NAA usually provides highly optimistic predictions of algae fuels. Optimism is to be appreciated, but it is fairly obvious to me that the NRC report is based on a better scientific and technical understanding of the ground realities. Will someone be able to prove NRC wrong? Lets hope for all our sakes that they do, but in the context of reporting/assessing the future of algae fuels with the existing intelligence, the contents in the NRC report will be agreed to by most experts who have done an in-depth study of this field. Being one of the co-authors for one of the most comprehensive industry reports on this topic - the Comprehensive Oilgae Report - I feel most times to be agreeing with the NRC report. Would like to hear from the rest
