  1. Characterization and high expression of recombinant Ustilago maydis xylanase in Pichia pastoris.

    Biotechnology Letters 37(3):697 (2015) PMID 25381595

    A recombinant xylanase gene (rxynUMB) from Ustilago maydis 521 was expressed in Pichia pastoris, and the enzyme was purified and characterized. Phylogenetic analysis demonstrated that rxynUMB belongs to glycosyl hydrolase family 11. The Trp84, Trp95, Glu93, and Glu189 residues are proposed to be pre...
  2. Enhanced photo-H2 production by unsaturated flow condition in continuous culture.

    Biotechnology Letters 37(2):359 (2015) PMID 25257592

    A biofilm photobioreactor under unsaturated flow condition (BFPBR-U) is proposed using a polished optical fiber as the internal light source for photo-H2 production in continuous culture. The main chamber was filled with spherical glass beads to create the reaction bed and the cells were immobilized...
  3. Hairy root biotechnology of Rauwolfia serpentina: a potent approach for the production of pharmaceutically important terpenoid indole alkalo...

    Biotechnology Letters 37(2):253 (2015) PMID 25326172

    Hairy root cultures of Rauwolfia serpentina induced by Agrobacterium rhizogenes have been investigated extensively for the production of terpenoid indole alkaloids. Various biotechnological developments, such as scaling up in bioreactors, pathway engineering etc., have been explored to improve their...
  4. Preparation and application of collagen scaffold-encapsulated silver nanoparticles and bone morphogenetic protein 2 for enhancing the repair...

    Biotechnology Letters 37(2):467 (2015) PMID 25326174

    The healing of contaminated/infected bone defects is a significant clinical challenge. Here, a novel collagen scaffold composite encapsulating silver nanoparticles (AgNP) and bone morphogenetic protein 2 (BMP-2) was prepared to enhance the healing of infected bone defects. Collagen scaffolds conjuga...

    Biotechnology Letters 17(11):1233 (1995)

  8. A new system for the expression of recombinant antibody in mammalian cells

    Biotechnology Letters 17(2):135 (1995)

  9. Transitory plasmid instability during the exponential phase of growth of a recombinantEscherichia coli

    Biotechnology Letters 16(11):1113 (1994)

  10. A novel bacterial thermostable alpha-amylase system produced under solid state fermentation
