2.4.1. BC production using WBY hydrolysates as nutrient source
The prepared seed inoculum (9%, v/v) was transferred into a glass vessel (500 mL) containing different treated WBY hydrolysates as described above after adjusting their pH to 5 using 2 M NaOH and they were cultivated statically at 30 °C for 14 days.
