Characterization of the hexahydropolyprenols of Aspergillus fumigatus Fresenius.
The isolation and properties of a group of alcohols from the mycelium of Aspergillus fumigatus Fresenius are described. Mass-, nuclear-magnetic-resonance- and infrared-spectrometric studies coupled with evidence from ozonolytic degradation and chromatography show the mixture to contain hexahydroprenols-18, -19, -20, -21, -22, -23 and -24. Each contains a saturated ;hydroxy-terminal' isoprene re...
متن کاملLow cost single-step purification of endoglucanase from Aspergillus fumigatus ABK-9.
Low cost agro-waste was used as adsorption support for single-step purification of endoglucanase from the culture filtrate of A. fumigatus ABK-9. Among various agro-waste substrates, 1% NaOH pretreated rice bran was proved to be the best for adsorbing about 74.8 and 71.1% of endoglucanase at 4 degrees C and 10 degrees C respectively. Langmuir type adsorption isotherm at 4 degrees C showed maxim...
متن کاملPurification and Characterization of a Low Molecular Weight Xylanase from Solid-state Cultures of Aspergillus Fumigatus Fresenius
A xylan-degrading enzyme (xylanase II) was purified to apparent homogeneity from solid-state cultures of Aspergillus fumigatus Fresenius. The molecular weight of xylanase II was found to be 19 and 8.5 kDa, as estimated by SDS-PAGE and gel filtration on FPLC, respectively. The purified enzyme was most active at 55C and pH 5.5. It was specific to xylan. The apparent K m and V max values on solubl...
متن کاملIsolation, purification and characterization of 5'-phosphodiesterase from Aspergillus fumigatus
5'-Phosphodiesterase (5'-PDE) catalyzes the hydrolysis of ribonucleic acid to obtain a mixture of ribonucleotides, such as 5'-guanosine monophosphate and 5'-adenosine monophosphate. In this study, a 5'-PDE was newly isolated and purified from Aspergillus fumigatus. Following purification, this enzyme exhibited a specific activity of 1036.76 U/mg protein, a molecular weight of 9.5 kDa, and an op...
متن کاملCloning, purification, and characterization of a heat- and alkaline-stable endoglucanase B from Aspergillus niger BCRC31494.
Endoglucanase B (EGLB) derived from Aspergillus niger BCRC31494 has been used in the food fermentation industry because of its thermal and alkaline tolerance. It was cloned and expressed in Pichia pastoris. According to sequence analysis, the gene open reading frame comprises 1,217 bp with five introns (GenBank GQ292753). According to sequence and protein domain analyses, EGLB was assigned to g...
