RT Journal Article SR Electronic T1 Effect of Synthetic Polylysine on Fungi JF Science JO Science FD American Association for the Advancement of Science SP 1664 OP 1666 DO 10.1126/science.132.3440.1664 VO 132 IS 3440 A1 Buchanan-Davidson, Dorothy J.

YR 1960 UL http://science.sciencemag.org/content/132/3440/1664.abstract AB The synthetic, basic poly-α-amino acid, polylysine, had antifungal activity against plant pathogens (three strains of fusaria, three isolates of verticillia, and Ceratocystis fimbriata) and against the human pathogens (Trichophyton mentagrophytes, T. rubrum, and Candida albicans) in vitro. It inhibited penetration of Ceratocystis fimbriata on sweet potato slices. Polylysine inhibited the infection of tomato cuttings by Flsarium oxysporum f. lycopersici, but it was also toxic to the plants.
