Characterization of a thermostable α-glucosidase from Geobacillus thermodenitrificans F84a
Isolation of novel thermophilic bacilli has received considerable attention among the scientific community in whole world because of their biotechnological importance as they possess unique enzymes with thermal activity and stability. Of the thermophilic enzymes, we were interested in α-glucosidases which catalyze hydrolysis of terminal non-reducing α-D-glucosidic linkages of oligoand polysacch...
متن کاملLantibiotics from Geobacillus thermodenitrificans.
The lantibiotic nisin has been used as an effective food preservative to combat food-borne pathogens for over 40 y. Despite this successful use, nisin's stability at pH 7 is limited. Herein, we describe a nisin analog encoded on the genome of the thermophilic bacterium Geobacillus thermodenitrificans NG80-2. This analog termed geobacillin I was obtained by heterologous expression in Escherichia...
متن کاملMolecular Engineering of the Geobacillus stearothermophilus α-Amylase and Cel5E from Chlostridium thermocellim; In Silico Approach
Background: Considering natural thermal stability, Geobacillus stearothermophilus amylase and Cel5E from Clostridium thermocellum are good candidates for industrial applications. To be compatible with the industrial applications, this enzyme should be stable in the high temperatures, so any improvement in their thermal stability is valuable.Objectives: Us...
متن کاملExpression and Characterization of Geobacillus stearothermophilus SR74 Recombinant α-Amylase in Pichia pastoris
Geobacillus stearothermophilus SR74 is a locally isolated thermophilic bacteria producing thermostable and thermoactive α-amylase. Increased production and commercialization of thermostable α-amylase strongly warrant the need of a suitable expression system. In this study, the gene encoding the thermostable α-amylase in G. stearothermophilus SR74 was amplified, sequenced, and subcloned into P. ...
متن کاملPurification and Characterization of a Thermostable Lipase from Geobacillus thermodenitrificans IBRL-nra
Thermostable lipase from Geobacillus thermodenitrificans IBRL-nra was purified and characterized. The production of thermostable lipase from Geobacillus thermodenitrificans IBRL-nra was carried out in a shake-flask system at 65°C in cultivation medium containing; glucose 1.0% (w/v); yeast extract 1.25% (w/v); NaCl 0.45% (w/v) olive oil 0.1% (v/v) with agitation of 200 rpm for 24 hours. The extr...
