    Narsi asked Algae Strains for Toxic Ingredient Absorption in Large-scale Cultivation of Microalgae in Diverse Wastewater 9 months ago

    Are there algae strains that could consume toxic components in waste water, such as mercury? Can someone list down such strains that can decrease the toxicity of waste water from specific industries?

      need ones that tollerate high levels of heavy metals like Cadmium Lead ect. for the mining industry, I have had a special request from a client. ?? Latin names anyone? strain numbers?

    Narsi asked Cultivation of Microalgae in Industrial Wastewater in Large-scale Cultivation of Microalgae in Diverse Wastewater 9 months ago

    Industrial wastewater treatment using algae poses significant challenges because the wastewater composition from different industries are dramatically different from each other. What is the best way for a company to devise frameworks for algae cultivation in industrial waste water so that some kinds of synergies can be obtained across industries?

      @donmichael - I agree with you that having differentiated systems could work as we have perhaps a hundred thousand algae species. The problem I think with such an amount of diversity is the need for so much more R&D, pretty much for each strain, as against one or two R&D efforts if it were for a more homogenous medium... What are your thoughts?

    Akshaya posted Sustainable Production of Algae Biodiesel by using Waste from Landfill in Large-scale Cultivation of Microalgae in Diverse Wastewater 8 months ago

    The basis of this project includes development of an algae bioreactor and biodiesel process facility at the Development Authority of the North Country (DANC) landfill in Rodman, NY. This facility will be designed to grow the alga Chlorella protothecoides for the purpose of producing biodiesel from extracted lipids. The project is unique in that it uses waste from existing processes at the landfill to support algal growth. Electric power generators at DANC use biogas collected from the landfill to produce a significant amount of waste heat that is currently being released to the atmosphere. This heat could be captured to aid several phases of algae cultivation. This research will also examine the feasibility of using landfill leachate as a growth medium. Leachate is produced as a result of garbage decomposition and the infiltration of rainwater through the waste materials, and is found to contain several nutrients that are necessary for algal growth when diluted with freshwater. The specific goal of this project is to determine the most feasible and effective method of using these resources, while optimizing algal lipid production to generate enough biodiesel to displace at least 20% of the landfill’s petroleum diesel use.

    Inna suggested nonsense, may be in Large-scale Cultivation of Microalgae in Diverse Wastewater 9 months ago

    It is possible to take mercury in captivity? For example, within synthesized by algae polymers?

      Yes, it will be a problem. But in principle, the system with mercury captured by algae exopolymers may be created, for example, if strains have a strong mercury reducing activity. I have read a research article about immobilized Klebsiella with high Hg reductase activity. It seems to me that nanoparticles which reduce mercury also can be constructed.

    Inna suggested MerA homologues in Large-scale Cultivation of Microalgae in Diverse Wastewater 9 months ago

    We have found in Chlorella genome 10 hits with homology to merA. We note that all hits have a strong correspondence to domain stucture of mercuric reductase.
