Pengaruh Variasi Media Pertumbuhan terhadap Aktivitas Peredaman Radikal Bebas DPPH Ekstrak Kapang Endofit Isolat Cb.D1

Endophytic fungi are a source of antioxidant compounds in nature. The low yield extracts and active produced is one the limiting factors for using endophytic as natural compounds. Modification growth media an alternative solution to overcome this problem. This study aimed determine effect conditions, belonging carbon nitrogen sources different initial pH fermentation, on through DPPH radical scavenging activity extract Cb.D1 isolated from cinnamon plant leaves. culture was propagated Czapek Dox Broth basal liquid medium with agitation speed 120 rpm at room temperature 14 days. used were glucose, sucrose, soluble starch. natrium nitrate, ammonium yeast extract. conditions 5, 7, 9, ethyl acetate extraction solvent. results obtained that variation also can increase Cb.D1. Glucose, extract, 9 best gain it. substitution free fungal compared sources. highest contain sucrose nitrate 5. Variation affected their activity.
