In this project, Subalusky specifically investigates what ecosystem metabolism reveals about primary and secondary production in the Mara River. Primary production refers to the production of biomass by plant life such as algae, whereas secondary productivity refers to biomass ...
Algae Biomass Summit 2020 discussed Alternative Products from Algae. ...
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, ...
BUCHI Mini Spray Dryer B-290: Yield and total yield determination in spray dried microalgaes Recently, microalgal biomass has been recognized as a promising alternative source of raw material for biofuel production. Algal biomass has several advantages that may help to meet the need for the global demand of transport fuels, such as rapid growth rate, high lipid content, small land usage, and ...

Department of Energy (DOE), announced $15 million in funding for three projects that will work to improve algal biomass yields to reduce production costs of algae-based biofuels and bioproducts. The projects include Global Algae Innovations (San Diego, California), Algenol Biotech LLC (Ft. Myers, Florida), and MicroBio ...
The effect of chemical coagulation and biological auto-flocculation relative to zeta potential was examined to compare flotation and sedimentation separation processes for algae harvesting. Experiments revealed that microalgae separation is related to auto-flocculation of Anabaena spp. and requires chemical coagulation for the whole period of microalgae cultivation. In addition, microalgae ...
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. ...
Water recycling is an effective way to reduce water consumption in the industrialization of microalgae-based biomass/bioenergy production. The soluble algal products (SAP) which inhibit the microalgae growth will accumulate in the recycled water. Therefore, the ozone oxidation treatment of SAP produced by Scenedesmus sp. LX1 was studied to reduce the inhibition of SAP. The experimental ...
The production of different species of microalgae in consortium with other micro-organisms from wastewaters may represent an alternative process, to reduce the costs, for obtaining biofuels. The aim of this study was to evaluate the influence of pre-ultraviolet disinfection (UV) in the production of lipids from biomass produced in high rate ponds. Two high rate algal ponds were evaluated: a ...
True algae and blue-green algae both utilize some form of chlorophyll to perform photosynthesis. True algae are essentially plants. Blue-green algae are actually bacteria that exhibit a blue or green color, similar to true algae, but contain cellular structures typical of bacterial cells. True ...
Recycling a portion of gravity harvested algae promoted the dominance of a rapidly settling colonial alga, Pediastrum boryanum (P. boryanum) and improved both biomass productivity and settleability in High Rate Algal Pond (HRAP) treating domestic wastewater. ...
Algal monocultures (Chlorella sorokiniana and Botryococcus braunii) and algal communities native to clarifiers of a wastewater treatment plant were batch cultivated in (1) clarified effluent following a biochemical oxygen demand (BOD) removal reactor post-BOD removal clarified effluent (PBCE), (2) clarified effluent following a nitrification reactor post-nitrification clarified effluent (PNCE), ...
This paper projects a positive outcome for large-scale algal biofuel and energy production when wastewater treatment is the primary goal. Such a view arises partly from a recent change in emphasis in wastewater treatment technology, from simply oxidising the organic matter in the waste (i.e. removing the biological oxygen demand) to removing the nutrients – specifically ...
Algal/bacterial biomass production in the HRAPE (15.2 g/m2/d) was improved by CO2 addition by ∼30% compared with that of the control HRAPW (10.6 g/m2/d). ...
