===Experiment 1: Light impact=== | |||
* Label the two vessels as "Light" and "Dark" using a marker or tape. | |||
* Measure equal amounts of water (e.g., 100 ml) and pour it into each vessel. | |||
* Add an equal volume of cyanobacteria culture (e.g., 5 ml) to each vessel, ensuring that the initial concentration is the same for both. Gently swirl the vessels to mix the water and cyanobacteria. | |||
* Place the "Light" vessel under a bright lamp or in a sunny spot near a window, ensuring it receives consistent light exposure throughout the experiment. | |||
* Place the "Dark" vessel in a dark area, such as a cupboard or a box, where it will not be exposed to any light. | |||
* Observe the vessels for a period of 6-8 hours. Pay close attention to the "Light" vessel and look for tiny bubbles forming around the cyanobacteria. These bubbles are oxygen produced as a result of photosynthesis. | |||
* Take notes on your observations, including the presence of bubbles in the "Light" vessel, and any differences in the appearance or behavior of the cyanobacteria between the two vessels. | |||
* At the end of the observation period, compare your findings and discuss how light exposure influenced the cyanobacteria's ability to perform photosynthesis, as evidenced by the formation of oxygen bubbles. | |||
===Experiment 2: Building a simple bioreactor=== | |||
* Clean glas containers | |||
* Construct ports and making them air tight | |||
* Add aluminum foil to protect ports after autoclaving | |||
* Add tubing for bubbling | |||
* Test the set-up regarding | |||
* Bubbling | |||
* Mixing | |||
* Various | |||
* Fill with destilled water | |||
* Autoclave | |||
