Xylan is the major component of plant biomass and polysaccharide made from units of xylose. Hydrolysis of xylan is considerable interest for various biotechnological applications. To efficiently and stably hydrolyze xylan, the endoxylanase from Bacillus sp. was cloned and expression plasmid, pRSδ-xylp (YIp type) was constructed. This plasmid contains MFαsignal sequence for secretory expression of endoxylanase and δ-sequence for target integration. The pRSδ-xylp was transformed into Saccharomyces cerevisiae SEY2102△trp and the endoxylanase activity reached 4.4 unit/㎖ and the mitotic stability was 100%. The pRSδ-xylp was sequentially transformed in SEY2102△trp/pRSδ-xylp transformant by selective marker rescue and repeated integration and the endoxylanase activity was sequentially increased to 5.7unit/㎖. To examine the integration position and copy number of xylp gene, PFGE and southern hybridization were conducted. The xylp gene was integrated into Chr Ⅱ,Ⅳ,Ⅴ,Ⅶ,Ⅷ,Ⅻ andⅩⅣ of yeast and most of xylp gene was specially concentrated in Chr Ⅴand Ⅷ by multiple integration. The copy number was also increased with the endoxylanase activity increase. These results suggested that the endoxylanase from Bacillus sp. was stably expressed and the enzyme activity was sequentially increased by using multiple genome integration.
