Table 4.
Composition of the main species present in the charge deconvoluted ESI FT-ICR MS (negative ion mode) of the lower molecular mass fraction of the degraded PS isolated from the LPS of A. veronii Bs19, recorded with unspecific fragmentation. Mass fragments (marked with capital letters) are labeled according to the nomenclature of Domon and Costello [33].
