Streptomyces lunalinharesii sp. nov., a chitinolytic streptomycete isolated from cerrado soil in Brazil.
A novel chitinolytic actinomycete isolated from a Brazilian cerrado soil, designated strain RCQ1071(T), was assigned to the genus Streptomyces on the basis of chemical and morphological characteristics. The almost-complete nucleotide sequence of the 16S rRNA gene of strain RCQ1071(T) was determined and also placed this strain in the genus Streptomyces. Phylogenetic analyses of 16S rRNA gene sequences showed that strain RCQ1071(T) formed a long branch in a group related to Streptomyces albulus, sharing approximately 98 % sequence similarity. Levels of DNA-DNA relatedness between strain RCQ1071(T) and members of this group, namely S. albulus DSM 40492(T), Streptomyces noursei DSM 40635(T) and Streptomyces yunnanensis DSM 41793(T), were 38.3, 27.8 and 46 %, respectively, strongly indicating that strain RCQ1071(T) was not a member of any of these species. The relatively long branch length within a stable clade together with the phenotypic data strongly supported that strain RCQ1071(T) represented a novel species. Based on the combination of physiological, phylogenetic and genomic data, strain RCQ1071(T) is suggested to represent a novel species of the genus Streptomyces, for which the name Streptomyces lunalinharesii sp. nov. is proposed. The type strain is RCQ1071(T) (=ATCC BAA-1231(T) =CIP 108852(T) =DSM 41876(T)).
