During the preliminary screening process, the experiments were carried out for 7 days, and it was found that at the 96 h, the maximum production occurs. Hence, experiments are carried out for 96 h. All the experiments were carried out in duplicate and the average values are reported as mean ± SD calculated using MS Excel.
