Algea - Watch it budding
Raphidocelis subcapitata is a sweet water algae that is used in environmental testing. Growth and budding can be synchronized by light. CASY allows to follow the budding process very precisely.
R. subcapitata has a cell size of 6µm and each mother cell buds into 4 daughter cells. As budding begins, increasing numbers of single daughter cells appear. The budding continues over a time period of 4 to 5 hours increasing the number of single buds. In parallel the mother cells at 6µm almost completely disappear.
CASY can also be used indirectly for applications like standardizing algae quantities for feeding Daphnia. Since Daphnia feeding behavior is influenced by water quality, CASY was employed to measure the initial algae concentration and the remaining amount after one hour.
