A New Species of Actinomycete, Amycolata alni

A new species of the genus Amycoluta, Amycolata alni, is proposed for strains which were mostly isolated from root nodules and rhizospheres of alder trees and were formerly assigned to the species Amycoluta uutotrophicu. Strains of this new species could be differentiated from representatives of A. uutotrophica by deoxyribonucleic acid homology data (17 to 29% relatedness), as well as by their ability to grow on salicin and D-gluconate, their failure to produce acid from cellobiose and meso-inositol, their resistance to penicillin and carbenicillin (10 pg/ml), and other characteristics. Phenotypic features and low levels of deoxyribonucleic acid homology distinguish A. alni from two other species of the genus Amycolatu, Amycoluta suturneu and Amycolata hydrocuibonoxydans. The type strain of A. alni is strain 3LS (= VKM Ac-901).
