Fig. 7From: Production and bioprocessing of camptothecin from Aspergillus terreus, an endophyte of Cestrum parqui, restoring their biosynthetic potency by Citrus limonum peel extractsMetabolic stability of A. terreus for sustainable production of camptothecin with the multiple subculturing. A The yield of camptothecin with the subsequent cultural generations of A. terreus. B The 3rd generation of A. terreus was cultured on the optimized medium, amended with different concentrations of lemon peel extracts (0.5–10 mL), incubated at standard conditions, then camptothecin was extracted and quantifiedBack to article page
