Spores found germinated well with a reduction in absorbance of 30% or more with cellobiose (250 mM), dextrose (50 mM), 2-deoxy-D-glucose (150 mM), glucosamine (150 mM), maltose (250 mM), methyl-α-D- glucoside (300 mM), sorbose (200 mM), starch (150 mM) and xylose (150 mM).
This distinction in recognition of sugars by spores can be speculated to link with permeability of the outer spore layers, for different germinant to the inner membrane [21], germinant specificity [22, 23] and GR (nutrient germinant receptors) level [15]
