Quenching method	Organisms
Centrifugation of the liquid culture media and filtration	Bacteria (Forner et al., 2013; Hou et al., 2012; Viegelmann et al., 2014)
Addition of solvent and freezing at − 20 °C	Cyanobacteria (Luzzatto-Knaan et al., 2017; Winnikoff et al., 2014)
Freeze-drying after harvesting	Cyanobacteria (Kleigrewe et al., 2015)
Addition of solvent and centrifugation	Bacteria (Bose et al., 2015)
Frozen and stored at − 20 °C	Sponge (Ali et al., 2013; Olsen et al., 2016; Reverter et al., 2018) Corals (He et al., 2014a)
