Water samples were filtered through electropositive
Virosorb 1 MDS cartridges (CUNO, Meriden, CO). Once
water samples were concentrated to a 30 mL volume, RNA
was extracted using a Trizol LS reagent (Invitrogen,
Carlsbad, CA) and chloroform. Aliquots of 300 μL of
water were mixed with 300 μL of PBS 1× and shaken vigorously
five times, leaving the vials on ice for one minute
between each shaking, and then centrifuged at 12,000 × g
for five minutes. The upper phase containing RNA was
transferred and 500 μL of Trizol added, gently mixing for
one minute before replacing on ice. This procedure was
repeated five times. Subsequently, 100 μL of chloroform
was added gently and shaken vigorously five times.
