Phyco-Flow Photobioreactor Installed at the University of Helsinki - Case Study
The Varicon Aqua team have recently returned from Finland, where we are pleased to have installed a top of the range Phyco-Flow System for the University of Helsinki. Researchers will use the tubular photobioreactor, situated on the Lahti campus (Faculty of Biological and Environmental Sciences), to cultivate microalgae in support of their on-going projects. One such project, Algae Factory, ...

Light Intensity
Microalgae Growth – Light Intensity If light is one of the key ingredients in photosynthesis, will more light always generate more productivity? Not exactly. Microalgae growth tends to have a consistent relationship with light intensity. Though the actual growth rates and intensities for different points in this curve will vary depending on many factors the general shape is consistent ...

Microalgae Growth - Light Spectrum
Microalgae need light to grow and photosynthesize, but not all light is created equal. The spectrum of light can have a big impact on how well your algae grows. The spectrum of a light is how bright it is at different wavelengths. This can be closely related to colour, e.g. a red LED looks red because it is emitting light with a wavelength of 650 nm. However, differences in light spectra can ...

Microalgae Growth - Overview of Key Parameters
Growing microalgae can seem complicated because there are so many factors that need to be just right for a successful algae culture. In this article we are going to briefly explain some of these factors and why they are important. Microalgae are an evolutionarily diverse group of organisms that come in many colours and shapes. They are united by their small size (1 – 100 µm for ...

Why is NASA taking astaxanthin to space?
It was only a matter of time until NASA (National Aeronautics and Space Administration U.S.A.) began to study the benefits of taking microalgae into space. Consider the resilience of microalgae combined with the many potential health benefits they can provide to the astronauts. Recently, NASA has been testing the growth of microalgae in space for its potential use during long-duration space ...

Polishing of municipal secondary effluent using native microalgae consortia
This work evaluates the use of native microalgae consortia for a dual role: polishing treatment of municipal wastewater effluents and microalgae biomass feedstock potential for biodiesel or biofertilizer production. An initial screening was undertaken to test N and P removal from secondary effluents and biomass production by 12 consortia. A subsequent treatment was performed by selected ...

Using ozonation to eliminate the inhibition of soluble algal products (SAP) of Scenedesmus sp. LX1 on its growth in microalgal cultivation for biomass/bioenergy production
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 ...

Investigation of initial pH effects on growth of an oleaginous microalgae
Chlorella sp. HQ for lipid production and nutrient uptakeUsing microalgae for synchronous biodiesel production and wastewater treatment is a promising technology. The growth, lipid accumulation and nutrient uptake characteristics of an oleaginous microalga Chlorella sp. HQ were evaluated at different initial pH from 5.0 to 11.0. The pH values changed towards neutrality and ended in the range 6.0–9.0 without artificial control. The alkalinity ...
