Anaerobic Co-digestion of Microalgae with Food Waste and Wastewater Sludge
… to optimize anaerobic co-digestion of microalgae biomass harvested from a wastewater treatment pond facility with locally-available wastes. The goal was to produce high methane yields and stable digestion without the need for supplemental alkalinity addition. A key research question was if …

Anaerobic Co-digestion of Wastewater Treatment Pond Algae with Wastewater Sludge
<p>Microalgae harvested from wastewater treatment ponds can be anaerobically digested to produce biogas, a renewable fuel resource. However, past experiments have shown some limitations of algae digestion. Algal cell walls are thought to be resistant to digestion, and the high protein content of …

Nonlinear Sliding Mode Observer Applied to Microalgae Growth
<p>Modeling biological processes, such as algae growth, is an area of ongoing research. The ability to understand the multitude of parameters that influence this system provides a platform for better understanding the dynamics of microalgae growth. Empirical modeling efforts look to understand …

Fabrication of TIO₂-embedded PVDF membranes and their application in algae membrane bioreactor systems
… were fabricated and applied for high-density algae cultivation in membrane algae bioreactors (MBR). Microalgae species Chlorella Vulgaris was cultivated in the MBR systems fed with artificial wastewater at a target solids retention time (SRT) of 25 days. Under steady-state conditions, the MBR …

Algae Lysis with Pulsed Electric Fields
<p>With growing interest in alternative fuels, algae lipid harvesting is seen as a possible source of biofuel. Algae species under consideration include Chlorella vulgaris, Chlamydomonas reinhardtii and Dunaliella salina due to lipid contents as high as 30% to 56% of their dry weight (depending on …

The impact of green macroalgal mats on benthic invertebrates and overwintering wading birds.
… areas of estuarine intertidal habitats and have biomass >1 kg m-2 (wet weight). One of the key metrics for assessment of the ecological condition status of estuarine features in Europe is the extent and biomass of macroalgal mats. The aim of this research is to establish whether the development …

Mitigation of ammonia gas from animal house using microalgae
<p>We suggest a strong potential of algae to mitigate ammonia gas from animal house and to be used as a high-value animal feed. Ammonia gas emission from animal manure decomposition is a major concern in animal housing operations. Excessive ammonia gas volatilization will affect both animal and …

Geographical assessment of algal productivity and water intensity across the United States
… requirements for commercial-scale production of algae biomass through a dynamic integrated thermal and biological modeling framework. Water demands were calculated through a validated dynamic thermal model which predicts temperature with an accuracy of -0.96 ± 2.72 °C and evaporation losses with …

The Effect of Pretreatment Methods on Methane Yield and Nutrient Solubilization During Anaerobic Digestion of Microalgae
<p>Microalgal biomass is a candidate feedstock for biofuel production. To improve the sustainability of algae biofuel production, following biofuel recovery, the biomass nutrients should be recycled for additional algae growth. Anaerobic digestion of algae or oil-extracted algae is a means of …

Systemic and Intracellular Trafficking of Long-chain Fatty Acids in Lactating Dairy Cattle
… cows were supplemented with rumen protected algae biomass or algal oil in a 4 × 4 Latin Square. Feeding lipid encapsulated algae supplements increased docosahexaenoic acid content in milk fat while not adversely impacting milk fat yield; however, docosahexaenoic acid was preferentially …

Effects of Short-Term Dewatering on Grazer Abundance and Algal Biomass in a Wastewater Treatment Algal Turf Scrubber
… is one of society’s most daunting challenges. Algae biomass is a promising renewable resource for biofuel production due to its efficient conversion of solar energy into chemical energy. Algal turf scrubbers (ATS™) systems mimic natural streams, flowing wastewater over hard substrates designed …

Harvesting natural algal blooms for concurrent biofuel production and hypoxia mitigation
… algal blooms and conversion of the harvested biomass into biofuels. An engineering model was developed to compare the energy efficiency of different harvesting methods and biofuel conversion techniques. The modeling data was largely compiled from a variety of literature sources, but was also …

Interactive effects of temperature and grazing by seagrass limpets (Siphonaria compressa and Fissurella mutabilis) on seagrass (Zostera capensis)
… feeding on epiphytic diatoms, filamentous algae and bacteria growing on blades on seagrass. Siphonaria compressa occurs exclusively in beds of Zostera capensis and is currently listed as critically endangered. Increasing sea temperatures have been found to directly and indirectly affect …
