Biomass production (A), spore count (B), determination of CFU.mL−1 of Bv5 strain (C), and quantification of crystal proteins production (D) by Bv5 strain in different dilutions of pulp wash with salts with and without addition of nitrogen (ammonium nitrate), after 72 and 96 h and fermentation. Means followed by the same letter did not differ from each other by the Tukey test (p < 0.05). The error bar corresponds to the standard error. (PwS) Pulp wash with salts without nitrogen balance; (PwS + N) Undiluted pulp wash with salts and nitrogen balance; (PWS + N 1:1) 50% pulp wash + 50% water with salts and nitrogen balance; (PWS + N 3:1) 75% pulp wash + 25% water with salts and nitrogen balance
