    摘要： The present disclosure is related to a method for increasing the ethanol concentration from the conversion of lignocellulose. The pretreated solid residues are mixed with ethanol-containing broth from the fermentation of xylose hydrolysate by Pichia stipitis and then are performed under the process of simultaneous saccharification and fermentation (SSF) with Sacharomyces cerevisiae and cellulase for converting cellulose to ethanol. The final ethanol concentration in broth as well as the ethanol productivity is increased at least 1.8 times in comparison of conventional process for lignocellulosic ethanol production.

    摘要： A cellulose hydrolase and a gene thereof are obtained by screening a cDNA genomic library constructed with Orpinomyces sp. Y102. The gene is 1071 base pairs long and comprises an open reading frame (ORF) for producing the cellulose hydrolase comprising 357 amino acids by translation. A transformed cell and a carrier carrying the gene are introduced. The gene is transferred to E. coli by transformation, such that E. coli can acquire activity of decomposing CMC, beta-glucan, and xylan. The cellulose hydrolase is multifunctional and is capable of decomposing cellubiose and directly decomposing fiber into glucose.

    摘要： A method for cleavage of the ether-linkage of polyethoxylates is described. A novel pure microbial culture, Pseudomonas nitroreducens TX1 (Depository No.: BCRC910228), is used under aerobic condition to cleave the ether-linkage adjacent to the carboxylated terminus or ethoxyl terminus. This method is useful to cleave sequentially ether-linkage of polyethoxylates in an aqueous buffer solution with an initial concentration of the polyethoxylates between 0.05% and 20%. This method is also effective for the cleavage of the ether-linkages in short-chain polyethoxylates with one to three ethoxyl units.
