Actinosporangiwn vitaminophilum sp. nov.

Abstract
A new Actinosporangium sp. is described, for which the name A. vitaminophilum is proposed. This organism produces new antibiotics called pyrrolomycins and is characterized by pseudosporangia lacking sporangial walls, nonmotile spores and a type I cell wall. It differs significantly from previously described Actinosporangium spp. in the cultural conditions necessary for pseudosporangium formation. The type strain of A. vitaminophilium is SF-2080 (= ATCC 31673).
