Abstract: Pretreatment of the corn stover powder by dilute sulphuric acid(solid-liquid ratio 1:20) at 130℃ for 30 min was carried out with 89.09% of the hemicellulose removed.After filtration,the xylose-rich corn stover pretreatment liquid,whose fermentable sugar was from hemicellulose hydrolysis only,consisting of 81.16% xylose and 15.27% glucose,was used to cultivate genetic recombinant Escherichia coli BL21 with human-like collagen(HLC) expression enhanced by 50.00% and 63.71% xylose consumption.

Key words: corn stover, Escherichia coli BL21, human-like collagen, combined sugar
