In lines 6 and 7, page 4 of our Bio-protocol paper www.bio-protocol.org/e2796, the unit “g” is incorrect, should be “mg”. The same mistake is repeated on page 7, lines 27 and 28. The correct text should be:

Procedure

Add 0.006% (w/v) of bromocresol purple free acid reagent grade (60 mg L^-1); 1 mM of CaSO₄ (172 mg L^-1) in sterile distilled water. Adjust pH to 5.7 using KOH or HCl. Pour the solution into an Erlenmeyer.
