Реферат: New antibiotic (I) is obtd. by culturing microorganisms of the order Actinomycetales, esp. the new strain Streptomyces griseus 587 (DSM 1471). (I) is characterised by its physicochemical properties: (1) IR absorption at 3400 2920, 1680, 1375, 1260, 1140 and 825 cm-1 (KBr); (2) elementary analysis C 63.2%, H 8.0%, N 4.7%, O 24.1% by difference); (3) optical rotatory dispersion spectrum with lambda max = 297 nm (+380 degrees, c=3 mg/10 ml CHCl3); (4) mass spectrum with fragment-ion peaks at 260, 205, 155, 152, 126, 112, 84, 69, 55 and 41. (I) is useful as a defoliant, desiccant, germination inhibitor and esp. herbicide active against mono- and dicotyledonous plants (pre- and post-emergence herbicidal activity against Lepidium sativum is exemplified). (I) also has fungicidal activity e.g. with MIC values of =1.0 against Pyricularia, Pellicularia and Sclerotinia spp. and yeasts.
