As part of our final work for chemical engineering bachelors degree we are working to improve the production of lipids using the green microalgae Scenedesmus dimorphus. To do so we will variate the nitrogen concentration (Urea from 1.2g/L to 2.4g/L) and nutrient deprivation time. We will also investigate the effect of CO2 as a form of agitation. The pH values will be recorded daily, also the algae concentrations and the Urea concentration will be measured every 3 days. For more information about this, you can enter to the back-ground area. You can also see photos of our set-up and videos. In this web page we will bring all the actualized information about the progress of our investigation. ||SPANISH|| Como parte de nuestro trabajo final del bachillerato en ingeniería química estamos buscando conocer las condiciones que mejoran o aumentan la producción de lípidos en un alga verde, en nuestro caso Scenedesmus dimorphus. Esto aumentaria la materia prima para la produccion de Biodiesel. En el espacio (Background) podran encontrar la propuesta sobre el trabajo que estamos llevando acabo. Utilizaremos este espacio para continuamente ir actualizando la información obtenida en el laboratorio.

1. In half of the beakers the algae had sediment during the weekend.
2. In a few they had rose up from the beakers and felt into the tank, minimizing its volume.
3. After shaking them manually they all look bright green and healthy.
4. The pH had risen in all, but the one with 1.8g/L urea had rise even more going from ~6.15 to ~7.10.
5. The algae in all 3 concentrations are growing nicely.
