Abstract

Aqueous extracts of fungal biomass (Aspergillus niger, A. flavus, Penicillium notatum, Fusarium oxysporum and the filtrates of their culture media) were analysed for their ability to enhance anthocyanin production in callus cultures of carrot (Daucus carota). A 2.5% mycelial extract of A. flavus gave max. elicitation; a 2-fold increase in anthocyanin was observed with max. productivity of 23.7% dry wt. Media filtrates of A. flavus induced a 1.25-fold increase in anthocyanin production (20.6% dry wt.). P. notatum and F. oxysporum were not as effective as A. flavus or A. niger. The contact time and the concn. required for max. elicitation of anthocyanin differed with the type of elicitor used. Qualitative analysis of anthocyanins revealed the presence of cyanidin glycosides in control and elicited cultures.
