  • 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 ...

  • Algae Photo Bioreactors (APB`s)

    ALGAE PHOTO-BIOREACTORS (APB’s) Absorption of CO2 and NOx from industrial exhaust gases and conversion of algal feedstock, as a discipline of ecological engineering. Algae, live in a wide range of aquatic environments and are a natural component of most aquatic ecosystems being found in both fresh, brackish and marine waters. They range in size from large macrophytic kelps to microscopic ...

  • Nitrogen and phosphorus pollution alter the mutual relationship between corals and algae

    phosphorus pollution change the relationship between the pistillata and the algae living inside its tissues, a recent study has found. The researchers say the pollutants, mainly from urban and agricultural discharges, affect algae photosynthesis and the essential transfer of carbon from algae to the coral. Nitrogen and phosphorus pollution change the relationship between the tropical coral ...

  • Realistic environmental mixtures of micropollutants in surface, drinking and recycled water: Herbicides dominate the mixture toxicity towards algae

    Mixture toxicity studies with herbicides have focused on a few priority components that are most likely to cause environmental impacts and experimental mixtures were often designed as equipotent mixtures; however, real world mixtures are made up of chemicals with different modes of toxic action at arbitrary concentration ratios. The toxicological significance of environmentally realistic ...

  • Development of algae–based technology to mitigate energy crisis in coal mining areas: a critical review

    Algal biofuels around the world represent a sustainable pathway to meet increasing demand for fuel and clean energy with reduced environmental impact. More than half of that mass consists of lipids or triacylglycerides which are also found in vegetable oils and are used to produce such advanced biofuels as biodiesel, green diesel, green gasoline and green jet fuel. Algal remediation technology ...

  • Seasonal Dynamics of Periphyton in a Large Tropical Lake

    Tropical aquatic systems are generally assumed to have little seasonality in productivity patterns. However, this study indicated that there was substantial seasonal variation in epilithic productivity and biomass in tropical Lake Tanganyika, due primarily to seasonal patterns in lake hydrodynamics that influence nutrient availability. Although they support much of the lake’s biological ...

  • Prevent Fish Kill in the Spring

    Pond Deicing Can Help Prevent Fish Kill Keeping the pond open will help keep oxygen in the water, attract water fowl and help prevent fish kills in the spring. The most common cause of fish kills is suffocation due to lack of dissolved oxygen. Most dissolved oxygen is produced by algae and aquatic plants through photosynthesis. A lesser but also important source of oxygen in water ...

  • Seasteading could be the answer to sustainably feeding 9 billion people

    Self-sufficient nation states in the middle of the ocean might be our ticket to a sustainable future. Oceans cover 71 percent of Earth’s surface, yet provide less than 2 percent of the food we eat. The growing demand for seafood, however — predicted to rise to 8 percent during the next decade — from an already depleted and exhausted ocean is forcing ...
