Amycolatopsis dongchuanensis sp. nov., an actinobacterium isolated from soil.

Abstract: A novel actinomycete strain, designated YIM 75904(T), was isolated from a soil sample that had been collected from a dry and hot river valley in Dongchuan county, Yunnan province, south-western China. The taxonomic position of the novel strain was investigated by a polyphasic approach. In phylogenetic analyses based on 16S rRNA gene sequences, strain YIM 75904(T) formed a distinct clade within the genus Amycolatopsis and appeared to be closely related to Amycolatopsis sacchari K24(T) (99.3% sequence similarity). Strain YIM 75904(T) had a type-IV cell wall, with no detectable mycolic acids, and had MK-9(H(4)) as its predominant menaquonine. Its cell wall contained meso-diaminopimelic acid, galactose, glucose and arabinose, and its major cellular fatty acids were iso-C(16:0), iso-C(15:0), anteiso-C(17:0) and anteiso-C(15:0). The genomic DNA G+C content of the novel strain was 68.5 mol%. Based on the results of physiological and biochemical tests and DNA-DNA hybridizations, strain YIM 75904(T) represents a novel species of the genus Amycolatopsis for which the name Amycolatopsis dongchuanensis sp. nov. is proposed. The type strain is YIM 75904(T) (=CCTCC AA 2011016(T) =JCM 18054(T)).

Observation of a Neutral Structure near the D(D)over-bar* Mass Threshold in e(+)e(-) -> (D(D)over-bar*)(0)pi(0) at root s=4.226 and 4.257 GeV

Abstract: A neutral structure in the D (D) over bar* system around the D (D) over bar* mass threshold is observed with a statistical significance greater than 10 sigma in the processes e(+)e(-) -> D+D*(-)pi(0) + cc and e(+)e(-) -> D-0(D) over bar*(0)pi(0) + cc at root s = 4226 and 4257 GeV in the BESIII experiment The structure is denoted as Z(c)(3885)(0) Assuming the presence of a resonance, its pole mass and width are determined to be [38857(-57)(+43) (stat) +/- 84(syst)] MeV/c(2) and [35(-12)(+11) (stat) +/- 15(syst)] MeV, respectively The Born cross sections are measured to be sigma[e(+)e(-) -> Z(c)(3885)(0)pi(0); Z(c)(3885)(0) -> D (D) over bar*] = [77 +/- 13(stat) +/- 17(syst)] pb at 4226 GeV and [47 +/- 9(stat) +/- 10(syst)] pb at 4257 GeV The ratio of decay rates B[Z(c)(3885)(0) -> D+D*(-) + cc]/B[Z(c)(3885)(0) -> D-0(D) over bar*(0) + cc] is determined to be 096 +/- 018(stat) +/- 012(syst), consistent with no isospin violation in the process, Z(c)(3885)(0) -> D (D) over bar*
