Cadmium ion biosorption by the thermophilic bacteria Geobacillus stearothermophilus and G. thermocatenulatus.
This study reports surface complexation models (SCMs) for quantifying metal ion adsorption by thermophilic microorganisms. In initial cadmium ion toxicity tests, members of the genus Geobacillus displayed the highest tolerance to CdCl2 (as high as 400 to 3,200 microM). The thermophilic, gram-positive bacteria Geobacillus stearothermophilus and G. thermocatenulatus were selected for further elec...
متن کاملEmended descriptions of Geobacillus thermoleovorans and Geobacillus thermocatenulatus.
Nineteen thermophilic, aerobic, endospore-forming bacterial strains were subjected to 16S rRNA gene sequence analysis. Eight of these strains had been received as cultures of Geobacillus kaustophilus, G. lituanicus, G. stearothermophilus, 'G. thermoleovorans subsp. stromboliensis', G. vulcani, 'Bacillus caldolyticus', 'B. caldotenax' and 'B. caldovelox', but they showed close relationships with...
متن کاملPurification and characterization of an acidic, thermophilic phytase from a newly isolated Geobacillus stearothermophilus strain DM12
Microbial phytases were applied mainly to animal and human foodstuffs in order to improvemineral bioavailability and food processing. In addition, phytases have potentialbiotechnological application in various other fields, such as environmental protection,aquaculture and agriculture. Bacillus sp. DM12, an isolate from a hot spring, produces phytase,which catalyzes the hydrolysis of phytic acid...
متن کاملAvicelase Production by a Thermophilic Geobacillus stearothermophilus Isolated from Soil using Sugarcane Bagasse
Studies were carried out on the comparative study of the production of Avicelase enzyme using sugarcane bagasse-SCB in two different statuses (i.e. treated and untreated SCB) by thermophilic Geobacillus stearothermophilus at 50oC. Only four thermophilic bacterial isolates were isolated and assayed for Avicelase production using UntSCB and TSCB. Only one isolate selected as most potent and ident...
