People use to substitute their lack of sunlight by traveling to warm places or taking Vitamin D. They start running after the last sunbeams because they know the impact of being without it. | People use to substitute their lack of sunlight by traveling to warm places or taking Vitamin D.

This reminded me of Euglena, the microorganism that is attracted by light. Do we share a similarity in this way? | This reminded me of Euglena, the microorganism that is attracted by light. Do we share a similarity in this way? | ||

== Developing an Euglena Experiment Kit == | |||
Experimenting with Euglena in different ways made me even more intersteted in this organism. Especially the experiments with the shapes were very exciting and fascinating. So I decided to develop a toolkit (or the prototype of a toolkit) which makes it easy to arrange similar projects. I still have more ideas what I could do with the tools I have and I am curious what kind of ideas other people have regarding this topic. | |||
''Remark:'' I developed this experiment kit based on the knowledge of Euglena I have by now. The main focus on this project is giving interested people the chance to experiment with Euglena artistically on a low budget. | |||
'''What is it?''' A playful installation which makes it possible to draw with the single-celled organism Euglena. If you have different ideas to enhance it - go for it! | |||
'''What can you do with it?''' The installation is made for experimenting with Euglena in connection with light, colors and shapes. People who are interested can use it for playing around and turn their pictures into a very different form of drawing. I think it is especially interesting because you can control the development of the outcome not completely. At some point you need to give up the control over your artwork and let Euglena surprise you. You can draw your very own picture, convert it into a mask and receive an Euglena based drawing as outcome. By taking a photo before the artwork fades, you can create a visual memory which can also be printed (e.g. on linen) as art print. | |||
By working on my experiments I wondered how I can connect this idea with my previous work. I thought about building a connection between humans reaching for light and the organisms that do the same. My first achievement is an Euglena painted picture which makes my thoughts visible. | |||

==Conclusion== | |||
===Cultivating Euglena=== | |||
'''After nearly one month of cultivating Euglena the color of all cultures is finally green. Time to sum up the results.''' | |||
One of the most important things to say is that in every vessel the Euglena increased to a preferable amount, independently from the ingredients I used for the medium. The big difference is the time they needed. | |||
Tube 1 and 2 were very fast because I used the medium I already cooked what means they have had two weeks to grow before I startet Experiment 1. So I was already able to recognize a medium amount of organisms after three days. | |||
Nevertheless I am convinced that the cheese and the fertilizer helped the growing because of some reasons: The concentration was nearly the same in Tube 1 and 2 and in the Erlenmeyer flask after 30 days. That means the growing in the flask speeded up so that in the end it reached the same concentration with a significantly smaller amount of Euglena in the beginning. Also, the tubes only contain 15ml and the Erlenmeyer flask 100ml - another sign that also without the chemicals a high amount of Euglena can be bred in a short time. | |||
Also I guess that it took longer in tube 3 and 4 because they contained the fewest nutrients. I used cheese and fertilizer but the water was distilled. | |||
There was no noticeable difference in the vessels in which I additionally put CO2 fertilizer once a week. | |||
'''My recommendation for growing Euglena:''' | |||
Miga’s recipe (pdf) in combination with a small piece of hard cheese, a warm and light place but no direct sunlight, at least three weeks time and some patience :) | |||
''Note:'' I don’t think the extra solution 3 of the medium is needed anymore because the cheese contains Vitamin B12. To substitute Vitamin B1 some wheat grain should be added as well. I often read that this I used for breeding Euglena too, for example [https://www.uni-weimar.de/kunst-und-gestaltung/wiki/images/Culturing-Euglena2.pdf here]. | |||
