Friulimicins: Novel lipopeptide antibiotics with peptidoglycan synthesis inhibiting activity from Actinoplanes friuliensis sp nov I. Taxonomic studies of the producing microorganism and fermentation

A strain that produces new lipopeptide antibiotics is a new species of the genus Actinoplanes for which we propose the name Actinoplanes friuliensis ( type strain: HAG 010964). The strain is an actinoplanete actinomycete havin g cell wall II composition and forming sporangia. Comparisons with Actinopl anes spp. which have similarities with our isolate, including fatty acid an alysis, showed that the isolate belongs to a new species. Taxonomic studies and fermentation are presented.
