Bioreactors for Algae Seed Train Inoculum to Maximize Production in Massive Systems
The Drive Towards Scalable and Efficient Algae Production Producing algae as a commodity for feed, pharmaceuticals, nutraceuticals, carotenoids, and pigments calls for expansive setups. Executing this production at scale and making this economical, vast installations like raceway ponds or extensive tubular systems are required. However, the efficiency of these systems hinges on a critical ...

Rhodomonas
Have you ever come across a beautiful reddish (and pink in my opinion) coloured algae? That algae may have been rhodomoas, one of our favourites! Why use Rhodomonas for feeding oysters and other aquatic animals? Particle Size Rhodomonas algae have medium cell sizes, which makes them an ideal food source for oyster larvae. The cells are well-suited for the small filtering apparatus of young ...

Photobioreactor (PBR) Features
Algae bioreactors (PBR) Features – Easy algae cultivation Traditional algal culture techniques are unreliable and labour & space-intensive. Our photobioreactors make algae growth simple by automating routine tasks. Algae grows incredibly dense in our PBRs’ custom-designed high surface area sealed tank and it stays clean as everything entering the PBr is sub-micron filtered. We ...

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 ...

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 ...

Rosebud Pilot Project - Case Study
Symbiotic Algae Cultivation System - Pilot Launch 2018 The Hamlet of Rosebud currently discharges 9,460 m3 of effluent from their 60 residences into a 30 year old septic field which is now failing. Symbiotic Envirotek Inc., in partnership with Wheatland County and the residents of Rosebud, intend to implement an Algae Cultivation BiofieldTM (ACS) that will replace the septic field and ...

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, ...

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. ...

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 ...

Toxicity evaluation of two typical surfactants to Dunaliella bardawil, an environmentally tolerant alga
Sodium dodecyl benzene sulfonate (SDBS) and cetyl trimethyl ammonium chloride (CTAC) are two kinds of surfactants widely applied in various industries. The tremendous direct discharge of these surfactants into natural waters has posed a significant threat to ecosystems. Dunaliella bardawil was employed in the present research to test the toxic effects of SDBS, CTAC, and their mixture on cell ...
