Grow algae in a photobioreactor

Algae grows in nature, but can also be cultivated in photobioreactor. We tell you more about this emerging trend.  


Algae in an open pond system

Many algae species are currently grown in an open pond system. Compared to an open (pond) system, a photobioreactor has a low risk of contamination and virtually no CO2 loss. We explain how culture in a photobioreactor works.


Algen in een fotobioreactor

In a photobioreactor, light is used, CO2 and specific nutrients are used to create photosynthesis.

Specific conditions for the algae can be controlled in a fully automated photobioreactor. Think, for example, of the optimal temperature, the nutrient supply, pH value, CO2 supply and biomass concentration in relation to the available light and more. These controlled conditions may differ for the different algae species and must therefore be perfectly matched to the species.

A photobioreactor generates a higher biomass concentration, faster growth and a completely clean algae culture compared to an open pond system.


Optimal biomass concentration

However, algae must be grown in ideal conditions.

The most optimal way of biomass concentration means that all available light is absorbed by the biomass. An algae culture that is too dense causes a larger dark zone and this can lead to loss of productivity through respiration.

On the other hand, too low a biomass concentration leads to loss of photons. This is especially the case during periods of high light intensity.


Positive research results

Studies done on the growth of algae in a photobioreactor indicate a positive effect on growth compared to open (pond) systems.

About Lgem

Algae can do a lot for our health. They have high levels of vitamins, minerals, proteins and other important substances for our body.

Because of this emerging trend, growing algae is more important than ever.

Growing algae can be done better, in an easy and affordable way. Lgem designs and produces reliable and innovative systems for growing algae and we control all the biochemical processes involved. It is important to us that our systems are low labour-intensive, energy efficient and scalable.
