Abstract
A Gram-negative, coccobacilli, non-spore forming and non-motile bacterium, designated PN1T, was isolated from a banana leaf collected in Mattra island, Thailand. This isolate was observed to grow optimally at 30 °C and pH 7.0, and to grow with 0–3 % NaCl. Comparative 16S rRNA gene sequence analysis showed that strain PN1T is closely related to members of the genus Roseomonas, exhibiting the highest 16S rRNA gene sequence similarity to Roseomonas aestuarii JC17T (96.5 %). The DNA G + C content of strain PN1T was determined to be 69.7 mol %. Based on physiological and biochemical tests, and genotypic differences between strain PN1T and the validly named species of the genus Roseomonas, it is proposed that the strain be classified as a new species of Roseomonas for which the name Roseomonas musae sp. nov. is proposed. The type strain is PN1T (= BCC 44863T = NBRC 107870T).
