Feeding Sugars to Algae Makes Them FatDepartment of Energy, Office of Science
Some microscopic green algae stop photosynthesizing and start accumulating fats and/or other valuable molecules when certain changes happen. However, scientists don’t know the details of those swift metabolic changes. A team examined a green microalga to better understand this process. After a few days of feeding this microbe sugar, it completely dismantles its photosynthetic apparatus while accumulating fat. In contrast, after the team stopped feeding it sugar, the microbe returned to its normal metabolism.
