TABLE 4.

LMW extracellular carbohydrate (expressed as percentage of total extracellular carbohydrate) generated by the addition of glycanase (final concentration of 10 μg/ml) to cultures^a

Strain genotype	% Extracellular carbohydrate in LMW form when indicated enzyme was added:
	Throughout culture incubation		Halfway through culture incubation		After removal of cells from culture
	ExsH	ExoK	ExsH	ExoK	ExsH	ExoK
exoK exsH	100	93	43	54	0	0
exoK exsH exoZ	100	100	46	51	4	5
exoK exsH exoH	59	21	9	6	0	0
