TABLE 2.

Substitution patterns in the LMW succinoglycan from various S. meliloti strains

S. meliloti strain	Molar ratio (substituent/repeat) or presence of substituent
S. meliloti strain	Pyruvate^a	Acetate^a	Succinate^a	Malate^b
Rm1021	1.00	0.70	1.40	−
NRG185	1.00	0.97	1.95	−
Rm41	1.00	0.80	0.78	+
TJR41	1.00	0.84	1.50	+

Determined by integration of diagnostic resonances in ¹H NMR analyses for strains NRG185, Rm41, and TJR41 (Fig. 5). Data for Rm1021 are from Wang et al. (53), although preliminary analyses in this study yielded similar results.

Determined by MALDI-MS and FAB-MS analyses (Fig. 3 and 4A) and verified by HPLC (Fig. 4B).
