Nystatin (NYS) is a fermentation-produced antibiotic of the polyene group.Commercial NYS is a mixture of compounds named NIS A1, A2 and A3.Current analysis undertook physical and chemical analyses in two samples of commercial nystatin (NYS I and NYS II).Moisture (Karl Fischer), spectroscopic (IR, UV and fluorescence) and thermal analyses (TGA and D
Portable antiquities (sometimes known as small finds or chance finds) are often recorded within most Historic Environment Records to a spurious level of precision.For example, finds located only within a parish, or general area, are often mapped within GIS systems to exact CORNER points.Similarly, finds known only to the nearest kilometre square ar
Glycoside hydrolases of families 32 (GH32) and 68 (GH68) belong to clan GH-J, containing hydrolytic enzymes (sucrose/fructans as donor substrates) and fructosyltransferases (sucrose/fructans as donor and acceptor substrates).In GH32 members, some of the sugar substrates can also function as inhibitors, this regulatory aspect further adding to the c
