The atmospheric pressure matrix-assisted laser desorption/ionization with ion trap mass spectrometry (AP-MALDI-ITMS) was investigated for its ability to analyse plant-derived oligosaccharides. The AP-MALDI-ITMS was able to detect xylooligosaccharides (XOS) with chain length of up to ten xylopyranosyl residues. Though the

Two novel aminooligosaccharides were separated from the culture filtrate of Streptomyces coelicoflavus ZG0656. Their chemical structures were determined by acidic hydrolysis, electrospray-ionization tandem mass spectrometry (ESI-MS/MS), and NMR spectroscopy. The compounds were named acarviostatins III0(-1) and III23 according to the

Bacillus amyloliquefaciens alpha-amylase (1,4-alpha-D-glucan glucanohydrolase. EC 3.2.1.1), which is commercially supplied as 'Bacillus subtilis alpha-amylase' does not cross-react immunologically with B. subtilis alpha-amylase. This enzyme (from B. amyloliquefaciens) was cleaved by treatment with CNBr into seven fragments. Peptide A was
