A new aminoglycoside antibiotic, S-11-A, was isolated from the fermentation broth of the 2-deoxystreptamine negative (DOS-) mutant of Bacillus circulans S-11. The structure of S-11-A was elucidated as 1-deamino-1-hydroxyxylostasin, which contains an intermediate of DOS biosynthesis (S-11-P) and has resistance to some aminoglycoside-inactivating enzymes. This is the first finding of antibiotic p...

Alcanivorax hongdengensis A-11-3(T) was isolated from an oil-enriched consortium enriched from the surface seawater of Hong-Deng dock in the Straits of Malacca and Singapore. Strain A-11-3(T) can degrade n-alkane and produce a lipopeptide biosurfactant. Here we report the genome of A-11-3(T) and the genes associated with alkane degradation.

During atrial extrastimulation, split His potentials, prolonged His-to-ventricular (H,V,) intervals and block distal to the His bundle deflection were observed in both preoperative and postoperative children with heart defects. His-Purkinje responses and refractoriness were identified in 31 of 78 (40%) pediatric patients (20 of 51 preoperative and 11 of 27 postoperative) during atrial extrastim...

In this paper the notion of Rees short exact sequence for S-posets is introduced, and we investigate the conditions for which these sequences are left or right split. Unlike the case for S-acts, being right split does not imply left split. Furthermore, we present equivalent conditions of a right S-poset P for the functor Hom(P;-) to be exact.
