An obligately anaerobic, mesophilic, cellulolytic bacterium, strain ISDgT, was isolated from forest soil. Cells of this isolate stained Gram-negative, despite possessing a Gram-positive cell-wall ultrastructure, and were motile, straight rods that formed spherical terminal spores that swelled the sporangium. Cellulose, pectin, polygalacturonic acid, starch, xylan, arabinose, cellobiose, fructos...
We investigated a potential for glucose production from cellulose material using two kinds of hyperthermophilic enzymes, endo-cellulase (EG) and beta-glucosidase (BGL). Two BGLs from hyperthermophile Pyrococcus furiosus and mesophile Aspergillus aculeatus were compared for complete hydrolysis of cellulose with P. horikoshii endo-cellulase (EGPh). The combination reactions by each BGL enzyme and...
This investigation constitutes a comparative study of the ribonucleic acid production during the course of growth at different temperatures of an obligate thermophile and a mesophile. A study of this nature aside from the quantitative data should provide information concerning the rate of ribonucleic acid production, the characteristic ribonucleic acid patterns obtained during the course of gro...
A 1.5 Å resolution X-ray structure of the catalytic module of Caldicellulosiruptor bescii family 3 pectate lyase is reported (PDB entry 3t9g). The resulting structure was refined to an R factor of 0.143 and an R(free) of 0.178. Structural analysis shows that this new structure is very similar to the previously solved structure of a family 3 pectate lyase from Bacillus sp. strain KSM-P15 (PDB en...
Deinococcus geothermalis is an extremely radiation-resistant thermophilic bacterium closely related to the mesophile Deinococcus radiodurans, which is being engineered for in situ bioremediation of radioactive wastes. We report that D. geothermalis is transformable with plasmids designed for D. radiodurans and have generated a Hg(II)-resistant D. geothermalis strain capable of reducing Hg(II) a...
Biphenyl dioxygenase from the psychrotolerant bacterium Pseudomonas sp. strain Cam-1 (BPDO(Cam-1)) was purified and found to have an apparent k(cat) for biphenyl of 1.1 +/- 0.1 s(-1) (mean +/- standard deviation) at 4 degrees C. In contrast, BPDO(LB400) from the mesophile Burkholderia xenovorans LB400 had no detectable activity at this temperature. At 57 degrees C, the half-life of the BPDO(Cam...
