Table 2 Definition of taxonomy Set 2.

Bacterial Class*	Number of sequences**	Gram reaction
Actinobacteria	395	+
Bacilli	640	+
α-Proteobacteria	324	-
β-Proteobacteria	365	-
(γ-Proteobacteria)	(3305)	-
Enterobacteriales [order]	2087
other γ-Proteobacteria [orders]	1218
δ/ε-Proteobacteria	284	-
(δ-Proteobacteria)	(2)
(ε-Proteobacteria)	(282)

* The groups used to define Set 2 are those with more than 200 sequences and are listed without parentheses.
** For each class each unique carbohydrate sequence was counted only once; a given sequence may occur in more than one taxonomic group.
