Nonomuraea terrae sp. nov., isolated from arid soil

Autor: Hilal Ay

Publikováno v: Archives of microbiology. 202(8)

During the course of isolating rare actinobacteria from unexplored habitats, strain CH32T was obtained from an arid soil sample in eastern Anatolia, Turkey. Polyphasic characterization and comprehensive genome analyses showed that the strain is a mem

Ethyl 2,3-diphthalimidoylpropanoate was effectively synthesized from ethyl propynoate with two equivalents of phthalimide catalyzed by triphenylphosphine in good yield. The choice of reaction media was important for selective synthesis of the desired

Kytococcus aerolatus sp. nov., isolated from indoor air in a room colonized with moulds

Autor: Peter Schumann, Jenny Schäfer, Peter Kämpfer, Karin Martin

Publikováno v: Systematic and applied microbiology, 2009, 32(5), 301-305; doi:10.1016/j.syapm.2009.05.004

A Gram-positive, coccoid bacterial isolate (02-St-019/1(T)), forming beige pigmented colonies was obtained from an indoor air sample. Based on 16S rRNA gene sequence similarity studies it was determined that this isolate 02-St-019/1(T) belonged to th
