Fig. 3From: Evaluation of olive mill waste as substrate for carotenoid production by Rhodotorula mucilaginosaChanges in physicochemical parameters of different mediums after Rh. mucilaginosa growth. pH (a), protein (b) and available sugars (c) were measured in the different AE concentrations before (Initial, empty bars) and after 4 days in culture (Final, dotted bars) Rh. mucilaginosa growth. Bars show the mean and S.D. (n = 4), *p ˂ 0.01, **p ˂ 0.001Back to article page
