Kojic acid is a secondary fungal metabolite that is commonly produced by many species of Aspergillus and Penicillium (Manabe et al., 1984). These fungi also produce mycotoxins that occur as components of distinctive secondary metabolite profiles, which can serve as reliable chemotaxonomic characters at the species level (Dorner, 1983; Frisvad & Filtenborg, 1983; Wicklow, 1984a). The mycotoxin a...

An effi cient whole plant regeneration method from callus cultures of Piper auritum was achieved through organogenesis derived from leaf tissue. Proliferating callus and shoot cultures derived from leaf tissue explants placed on Murashige and Skoog (MS) medium supplemented with 2.0 mg·L 2, 4-dichlorophenoxyacetic acid (2,4-D) plus 1.5 mg·L kinetin. Optimum combination of hormones (mg·L) for sho...
