A Sugar and lignin composition of the substrates generated from the two-stage neutral/alkaline sulphite steam pretreatment of lodgepole pine with and without the addition of sodium carbonate. B The enzymatic hydrolysis yields of the washed substrates derived from two-stage alkaline sulphite steam pretreatment of lodgepole pine. Enzymatic hydrolysis was conducted at a solids loading of 5% for 48 h using a cellulose loading of 35 mg protein per g cellulose
