This laboratory is working on the development of an efficient maintenance strategy for stream ecosystems. This study focuses on the extraction of Chlorophyll a from Chlorella vulgarisand compares two different homogenization methods : the Precellys® bead-beater and a hand-held, Con-Torque Tissue Homogenizer.
The total yield of Chlorophyll a extracted is higher with Precellys compared to the manual grinding method (Fig. 1).
Precellys ® 24-Dual : 11,500 µg/L (average of triplicate values)
Hand grind method : 7,000 µg/L (average of triplicate values)
