A scheme has been developed for the identification of thermophilic actinomycetes associated with hypersensitivity pneumonitis. Eighty strains, 10 Micropolyspora faeni, 6 Saccharomonospora viridis, 52 Thermoactinomyces candidus, 7 T. vulgaris, 4 T. sacchari, and 1 T. dichotomica, either isolated from patients' environment or received as authentic strains, were studied. In addition to the cultura...

The production and characterization of cellulase from thermophilic strain Bacillus sp. C1AC5507 was studied. For enzyme production, sugarcane bagasse was used as carbon source. The produced carboxymethyl cellulase (CMCase) had a molecular weight around 55 kDa and its activity varied between 0.14 and 0.37 IU mL in conditions predicted by Response Surface Methodology. The optimum temperature and ...

A thermophilic Methanosarcina strain was isolated from a digester fed with water hyacinths and inoculated with ground termites from the Congo. Optimal growth temperature was 55 degrees C. Methane production was at its optimum between pH 6.5 and 7.0. The bacterium grew on acetate, methanol and methylamines in the absence of growth factors, but could not use H2-CO2 or formate. H2-CO2 inhibited ac...

anaerobic digestion of organic solid waste (osw) from kitchen was conducted in completely stirred tank reactors (cstrs) under both mesophilic and thermophilic conditions. the lab-scale reactors were fed with the osw containing 10% of total solids (ts) at a hydraulic retention time (hrt) of 30 days (3.0-3.5 g-ts/l/d of volumetric loading rate). both mesophilic and thermophilic reactors exhibited...

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...

key dissimilarities between thermophilic and mesophilic anaerobic digestion of waste activated sludge (was) were experimentally studied in this research. typical was with total solids (ts) concentrations of 30 and 60 g/l were digested anaerobically in a batch digester at mesophilic and thermophilic temperatures. solids reduction, total cod changes, the production of different volatile fatty aci...

Thirty-one lactic acid bacterial strains from different species were evaluated for exopolysaccharide (EPS) production in milk. Thermophilic strains produced more EPS than mesophilic ones, but EPS yields were generally low. Ropiness or capsular polysaccharide formation was strain dependent. Six strains produced high-molecular-mass EPS. Polymers were classified into nine groups on the basis of th...

A novel anaerobic, moderately thermophilic bacterium, strain Cas60314(T), was isolated from hot oil-well production water obtained from an oil reservoir in the North Sea. The cells were Gram-negative, motile, straight rods. The salinity and pH growth optima were 2.0-3.0 % NaCl and 6.5-7.0, respectively. The optimum temperature was 58 degrees C. Strain Cas60314(T) had a fermentative type of meta...

Rubrobacter radiotolerans strain RSPS-4 is a slightly thermophilic member of the phylum "Actinobacteria" isolated from a hot spring in São Pedro do Sul, Portugal. This aerobic and halotolerant bacterium is also extremely resistant to gamma and UV radiation, which are the main reasons for the interest in sequencing its genome. Here, we present the complete genome sequence of strain RSPS-4 as wel...
