Última Purification and characterization of a phytoalexin elicitor from spores of the saprobe Mucor ramosissimus Rev. Bras. Bot. Simões,Kelly; Dietrich,Sonia M.C.; Hahn,Michael G.; Braga,Marcia R.. Plants accumulate antimicrobial compounds (phytoalexins) in response to a wide variety of microorganisms. Mucor ramosissimus Samutsevitsch is a saprobe capable of inducing phytoalexin production in soybean cotyledons and in the leaves of tropical Rubiaceae on whose surface it has been found. In the present study, the elicitor from M. ramosissimus was partially purified and the activity compared to that of a glucan elicitor isolated from Phytophthora sojae. Optimal isolation of the elicitor (based on fungal growth, yield of spores and elicitor activity) was achieved by autoclaving spores obtained from nine day-old cultures of the fungus. The elicitor was precipitated with ethanol and purified by chromatography on an anion exchange column, which retained the...

The present study aimed to evaluate the ability for biotransformation of the Diels-Alder adduct tricyclo[6.2.1.0(2,7)]undeca-4,9-dien-3,6-dione (1) and two synthetic derivatives by the saprobe fungus Mucor ramosissimus Samutsevitsch. Products from oxidation, isomerization and, regioselective and enantioselective reduction were achieved.
