Following thorough washing under running water for an hour, terminal growths of Aldrovanda were surface sterilized in 10% Clorox and placed directly into modified Gamborg B5 media without rinsing. New growth began 6-8 weeks later from the tips.
In our lab, we surface sterilize with 95% EtOH with great success.
