The original version of this article  unfortunately contained a mistake. The formula concentration described in the “Treatments” section was provided incorrectly. The corrected text is available below:
“The SBCG1 treatment was a solution with sodium bicarbonate and calcium gluconate, both at a concentration of 0.75 % (w/v); and SBCG2 had the same concentration of sodium bicarbonate than SBCG1, while the concentration of calcium gluconate was 1.5 % (w/v).
