CONTROLLED BREEDING AND SELECTION OF RESISTANT SPECIES Aegagropila linnaei and Taxiphyllum Barbieri FOR PREVENTING PETROLEUM BASED POLLUTION IN FRESH WATER RESOURCES

Our project consists of four processes:
1. Cultivating and the reproduction of these species in stable conditions,
2. Preparation of an experiment which consisted of adding 50 and 100 μl of diesel to 200 ml clean fresh water. And adapting them to a polluted enviroment,
3. Taking measurements of the colonies which have adapted to diesel,
4. Lastly, the selection of the strongest and best colony in the polluted environment.

Today, with the effect of both global warming and the increase of manmade pollutants, our clean fresh water resources are decreasing and becoming polluted day by day. Especially in recent years, thousands of square kilometers of ocean and sea water have been polluted as the result of accidents occurring in the world's largest oil production platforms. The same is true for fresh water sources, with waste being directed to fresh water sources. In our project, we wanted to reproduce a type of species that can ensure the continuity of aquatic life in polluted fresh water sources caused directly by petroleum and petroleum products. To ensure the selection of this species, we have exposed these species to the petroleum product in various proportions to create the most durable and strongest colony. In our study, by selecting two species that can grow and excist both on the surface of the water and just below the surface, we aimed to create colonies that can survive even if the petroleum product surrounds them.
