  • Algae research budget cuts... what now?

    Other than long overdue massive budget cuts, nothing has changed at the Department of Energy Algae Program. NAA has asked the DOE Secretary to review algae technologies giving private industry the opportunity to see if any algae technologies could be used in commercial algae production. While the DOE conducts advanced algal systems listening sessions, commercial algae producers are in commercial ...

  • Conical Bottom Tanks-Backstory - Case Study

    Originally we only offered the flat bottom tanks in our line of tanks. Eventually, fit was discovered that they are ideal for growing algae with natural sunlight, however some growers wanted to something a little more. Several customers wanted an easier way to harvest the algae from the growth chambers, particularly the bottom. Siphoning works for the flat bottom tanks, and is a great option for ...

  • Prevent harmful conditions from damaging crops with sensor alerts

    Your algae monitoring and control system is all set up, humming along efficiently, and the algae is growing well. Your solenoids are controlling the CO2 input so that your pH is always on target. Coolers (or heaters) are controlling your temperature. Maybe you even have automatic harvesting based on the density of your algae. But what happens if one of the devices breaks down? Pumps, valves, ...

  • Algae biomass cultivation in nitrogen rich biogas digestate

    Because microalgae are known for quick biomass growth and nutrient uptake, there has been much interest in their use in research on wastewater treatment methods. While many studies have concentrated on the algal treatment of wastewaters with low to medium ammonium concentrations, there are several liquid waste streams with high ammonium concentrations that microalgae could potentially treat. ...

  • Algae for Fertilizer

    As early as 1949, Spoehr and Milner (1) suggested that mass culture of algae would help to overcome global protein shortages. The basis for their optimism was that algae had a crude protein content in excess of 50 per cent and a biomass productivity of the order of 25 tons/ha/year. Ironically, in spite of the lamentably low per capita protein supplies in many parts of the world, mass cultivation ...

  • The treatment of (fish) ponds on an environmentally friendly manner with the usage of the LG Sonic case study

    Aquaculture, or aqua farming, is the cultivation of aquatic organisms, such as fish or shrimps, in a controlled environment. Where this happens in a closed water container, algae may occur that pollute the water and may damage the organisms grown. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally unfriendly, or all of these. LG Sonic uses ...

  • Ecological swimming pond case study

    In spring 2009 LG Sound installed an LG Sonic in an ecological swimming pond in France. This pond has been suffering from the growth of filamentous algae for a long period of time. Even when the algae where removed, they grew back within a couple of days. Swimming or any other recreational use was made impossible in this pond. The LG Sonic products can shift the balance in a watery ecosystem to ...

  • Recovery of photosynthesis and growth rate in green, blue–green, and diatom algae after exposure to atrazine

    We evaluated the recovery of photosynthesis and growth rate in green (Pseudokirchneriella subcapitata), blue‐green (Anabaena flos‐aquae), and diatom (Navicula pelliculosa) algae after pulsed exposure to atrazine. Subsequent to a grow‐up period of 24 to 72 h to establish requisite cell density for adequate signal strength to measure photosystem II (PSII) quantum yield, algae were exposed to a ...

  • Golden Algae Treatment Success

    The Challenge: In recent years Golden Algae has become a growing problem, causing fish kills and aquatic health issues in the fall and winter. Chemical management through the use of copper sulfate is not very effective even in the short term. In the long term, copper sulfate is toxic to many of the beneficial aquatic algae, bacteria and protozoa that can potentially compete with the golden ...

  • How did palm oil become such a problem — and what can we do about it?

    Production of this ubiquitous ingredient is devastating for the environment. Solutions are complex, but they are out there. Last August, from the window of a jet high over Sumatra, I counted nearly a dozen plumes of smoke rising from the vast jungles and plantations below. Some more than a half-mile wide, they looked like pillars holding up the sky. That week the Indonesian Disaster Mitigation ...

  • Pretreatment of brewery effluent to cultivate Spirulina sp. for nutrients removal and biomass production

    Due to the low concentration of nitrate and high contents of organics, brewery effluent was not suitable for the cultivation of Spirulina sp. This work changed the nutrient profile of brewery effluent effectively by dilution, addition of nitrate, and anaerobic digestion. The result showed that the optimum dilution rate and NaNO3 addition for brewery effluent were 20% and 0.5 g/L, ...

  • How Phytoplankton Endangers Fish Farms - and the Best Way to Combat the Threat

    Did you know that 99 percent of all biomass in the ocean is invisible to the human eye? To help put that in perspective, a teaspoon of seawater can hold over a million different living organisms – all tiny, often single-celled. Among them are phytoplankton – essentially the ocean’s microscopic plants and the foundation of the largest food chains on the planet. While too tiny ...

  • Project - MacroPro

    Seafood aquaculture is one of the fastest growing food production sectors, and there is a growing demand for organic farmed aquaculture products in many countries. Therefore, it is urgent to find alternative sustainable feed ingredients for aquaculture feeds to address these issues. A widely available but underutilised Nordic bio-resource is macroalgae (seaweed). Traditionally, macroalgae have ...

  • Photobiology of microalgae mass cultures: understanding the tools for the next green revolution

    Several obstacles and limitations currently prevent the industrial exploitation of microalgae for feed, food and biofuel production. Photobioreactors (closed systems for algae cultivation) suffer from high-energy expenditures for mixing and cooling, while cultures in large-scale open ponds, which have a more favorable net energy ratio, are unstable ecosystems in which maintaining selected strains ...

  • How to Analyze Photosynthesis in Plants: Methods and Tools

    Photosynthesis: Why is it important? Life as we know it would be impossible without photosynthesis. Outside of providing the essential elements that support life on earth, photosynthesis is of special importance to the food and agriculture industry, as well as for ecologists studying climate change. In addition, there are many commercial enterprises which depend heavily on photosynthesis. As a ...
