Isolation of Thermostable Lignocellulosic Bacteria From Chicken Manure Compost and a M42 Family Endocellulase Cloning From Geobacillus thermodenitrificans Y7

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...

Lantibiotics 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...

Purification 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...

Organic-Solvent and Surfactant Tolerant Thermostable Lipase, Isolated from a Thermophilic Bacterium, Geobacillus thermodenitrificans IBRL-nra

Lipases (triacylglycerol acylhydrolase, EC 3.1.1.3), catalyze the hydrolysis of long-chain triglycerides with the formation of diacylglyceride, monoglyceride, glycerol and fatty acids. Lipases are actively used in various industries which include food and diary, pharmaceuticals, organic synthesis and detergent and cosmetics. Thermostable lipases are commercially significant for their potential ...
