The scientists chose algae growing conditions to produce raw materials for biofuel production. This was reported by the Sao Paulo Research Foundation.
In recent years, the developed world has been trying to reduce the use of fossil fuels. One solution is to switch to biodiesel, which can be produced using algae. However, for this it is necessary to choose the most suitable type of algae and the technological process of their processing.
Luisa Fernanda and her colleagues succeeded in forcing the microalgae to produce the oils necessary for fuel synthesis. Botryococcus terribilis. The authors tested different growth patterns in both closed photobioreactors and open channels. After each experiment, scientists determined the composition of proteins, carbohydrates, lipids and pigments, first of all they were interested in the released fats. oils terribilis They are suitable for biofuel synthesis as they consist of more saturated and monounsaturated fatty acids as well as long chain hydrocarbons.
It turns out that the necessary oils are best allocated in conditions when algae grow under stress – with a lack of phosphorus and nitrogen. “When the body senses the lack of these nutrients, it starts accumulating lipids in order to survive. We used this ability to accumulate the corresponding metabolite. In other words, we were stressing the body by removing nutrients necessary for growth,” the authors write.
