BACKGROUND VanYn, encoded by the dbv7 gene (also known as vanYn) of the biosynthetic cluster devoted to A40926 production, is a novel protein involved in the mechanism of self-resistance in Nonomuraea sp. ATCC 39727. This filamentous actinomycete is an uncommon microorganism, difficult-to-handle but biotechnologically valuable since it produces the glycopeptide antibiotic A40926, which is the p...

Almost complete 16S rRNA sequences from seven Thermomonospora strains, Thermomonospora curvata, Thermomonospora formosensis, Thermomonospora fusca, Thermomonospora mesophila, Thermomonospora chromogena, Thermomonospora alba and Thermomonospora mesouviformis (a synonym of Thermomonospora alba) were determined and subjected to phylogenetic analysis together with the sequences from all the represe...

The lungs and viscera of 23 dwarf crocodiles (Osteolaemus tetraspis) obtained from markets in Brazzaville, were examined for pentastomid infection. Twenty-one animals were infected and harboured a total of 82 pentastomids, all belonging to the family Sebekidae and representing at least two genera and three species. Sebekia okavangoensis Riley & Huchzermeyer, was present in the body cavity and l...

8 strains of endophytic actinomycetes were successfully isolated from root nodules of Elaeagnus angustifolia by the methord of nodule-slicing respectively on three mediums S, FTW and DPM. And these strains were analyzed by 16S rDNA phylogenetic studies, the result showed that 5 of these strains belonged to Micromonospora, and the other 3 strains was Nonomuraea, Pseudonocardia and Planotetraspor...
