Production of B. stratosphericus lipase in submerged fermentation. Lipase activity was determined for submerged fermentations using (a) basal media (diamond); (b) basal media with acid pre-treatment coconut dregs (circle); (c) basal media with alkali pre-treatment coconut dregs (square); (d) basal media with acid pre-treatment coconut dregs and coconut oil (triangle); and (e) basal media with un-treated coconut dregs (χ) carbon. The fermentations were performed at 37 °C and pH 7. Error bars represent one standard deviation about the mean (n = 3)
