Arabidopsis IRX10 and IRX10-LIKE (IRX10-L) proteins are closely related members of the GT47 glycosyltransferase family. Single gene knock-outs of IRX10 or IRX10-L result in plants with either a weak or no mutant phenotype. However irx10 irx10-L double mutants are severely affected in their development, with a reduced rosette size and infrequent formation of(More)
An extracellular xylanase was purified to homogeneity from the culture filtrate of a thermophilic fungus, Thermomyces lanuginosus-SSBP, and its biochemical characteristics were studied. A yield of 70-80% was achieved through the procedures of 80%-satd. ammonium sulphate precipitation, DEAE-Sephadex A25 and quaternary aminoethyl (QAE)-Sephadex A25 column(More)
The beta-D-glucosidase produced by Thermomyces lanuginosus-SSBP was purified to apparent homogeneity. The purified enzyme consisted of two identical subunits with a native molecular mass of 200 kDa. The purified beta-D-glucosidase only hydrolysed the glucoside substrates containing a terminal, non-reducing beta-D-glucose residue and was active on both(More)
Thrombotic disorders have emerged as serious threat to society. As anticoagulant and thrombolytic therapies are usually associated with serious bleeding complications, the focus has now shifted to regulating and maintaining platelets in an inactive state. In the present study we show that nanosilver has an innate antiplatelet property and effectively(More)
Thermophilic fungi producing extremely high beta-xylanase and their associated hemicellulases have attracted considerable attention because of potential industrial applications. Thermomyces lanuginosus strain SSBP isolated from soil, produced beta-xylanase activity of 59 600 nkat ml-1 when cultivated on a medium containing corn cobs as substrate and yeast(More)
Many aquatic snails act as intermediate hosts for the larvae of trematodes, Fasciola hepatica and Fasciola gigantica, which cause the diseases fascioliasis and schistosomiasis. The WHO has tested several thousands of synthetic compounds for the control of the snail host. Although effective, these molluscicides have so far not proved themselves to be(More)
Bioenergy, particularly biofuel, from lignocellulosic biomass has been considered as one of the most promising renewable and sustainable energies. The industrial productivity and efficiency of microbial lignocellulolytic enzymes for cellulosic biofuel applications are significantly affected by pH of culture condition. This study established and compared(More)
In 424 African-American and 75 white subjects, we found that the -5 (TPI 592 A-->G), -8 (TPI 589 G-->A), and -24 (TPI 573 T-->G) variants in the triosephosphate isomerase (TPI) gene occurred frequently (41.0%) in the African-American subjects but did not occur in the whites. These data suggest that this set of polymorphisms may turn out to be one of the(More)
Mycelial stock cultures of Agaricus bisporus, A. Bitorquis, Pleurotus flabellatus, P. Sajor-caju, P. Ostreatus, P. Sapidus, Auricularia polytricha, Lentinula edodes, Morchella esculenta and Volvariella volvacea were maintained by frequent subculturing at an interval of two months and separately as wheat grain spawn in liquid nitrogen with 15 percent(More)
