Table 2 Dry matter (DM), volatile solids (VS) and chemical composition of the lignocellulosic materials used as substrates in anaerobic reactions

Materials	DM (% w/w)	VS^b (% w/w)	Chemical compositon^a [% (w/w) of dry matter]
Materials	DM (% w/w)	VS^b (% w/w)	Arabinose	Galactose	Glucose	Xylose	Mannose	Total lignin	Total carbohydrates
Birch	93.5	93.2	5.0	1.1	34.5	26.3	2.6	19.3^c	69.6
Spruce	93.4	93.0	1.3	1.9	38.0	5.6	11.5	27.0^c	58.3
LRR birch^b	94.5	93.9	0.0	0.1	9.1	1.1	0.1	80.3^c	10.5

^aValues represent sugars in their dehydrated polymeric form
^bLignin-rich residue recovered as insoluble fraction at the end of a 48-h enzymatic hydrolysis of steam-explosion birch with Cellic Ctec2
^cThe ratio of syringylpropane to guaiacylpropane (S/G ratio) was determined to be 2.8 and 5.8 for birch and LRR birch, respectively. For spruce only G could be quantified
