2.4.2. BC production using DOR aqueous extracts
The aqueous extracts, DOR40, DOR100 and DOR100H (45 mL)
were tested in sterilized 250 mL Erlenmeyers with 5 mL preinocula.
The initial pH value of the media was adjusted to
4.5 with NaOH 1 mol dm3 [32] and was not controlled during
flask cultivation. All the experiments were carried out in
duplicate and under sterile conditions.
