Euglena Investigation
What is Euglena?
A single celled microorganism
Contains both animal and plant features
Hard to classify due to its peculiarity
Often associated with algae
Euglena is a genus, containing > 1000 species.
Naturally found in freshwater and moist soil
An attractive 'superfood'
Is both an autotroph and heterotroph
Investigating Euglena Growth
Measuring the abundance of Euglena (dependent variable)
Concentration of Euglena (abundance) can be measured with a spectrophotometer
Provided a good sample, this measure can be incredibly precise and accurate
Requires a well sourced sample
Ensure an accurate calibration curve is used
Conditions to test (independent variable)
Light intensity
Light wavelength
Growth media pH
Temeperature
Controlled Variables
Bioreactor capacity & type
Timeframe Euglena are growing
pH level
Amount of growth media
Euglena as a food source? (& human endeavor)
Contains a rich source of vitamins and minerals
Relatively easy to farm
When feeding as an autotroph, sizeable amounts of carbon dioxide is absorbed
Lots of Euglena can be farmed in a relatively dense space.
As Euglena can feed through 2 processes, Euglena can adapt to what is available
Reproduces fairly quickly
