Bacteria from the phylum Deinococcus-Thermus are known for their resistance to extreme stresses including radiation, oxidation, desiccation and high temperature. Cultured Deinococcus-Thermus bacteria are usually red or yellow pigmented because of their ability to synthesize carotenoids. Unique carotenoids found in these bacteria include deinoxanthin from Deinococcus radiodurans and thermozeaxan...

In the present work, ability of different sodium-based salts like Na2CO3, Na2HPO4, Na2SO4 and Na2SO3 to salt out aqueous solutions two biodegradable non-ionic surfactants (Tergitol 15S7 Tergitol 15S9) has been demonstrated. We have empirically characterized immiscibility regions models Merchuk Othmer-Tobias equations were employed for binodal tie-line data, respectively. The effect phase formin...

A gene coding for GH5 endoglucanase exploited from metagnomic DNA data of bacteria in Vietnamese goats’ rumen was modularity structure including a catalytic module, fibronectin-3 like module and an X module. The recombinant enzyme sucessfully expressed E. coli purified. To study the effect some metal ions chemicals on activity, this study, we used tools Swiss-Prot, ProFunc, COFACTOR prediction ...

A new microbial strain was isolated from an arsenic-rich terrestrial geothermal environment. The isolate, designated HR13, was identified as a Thermus species based on 16S rDNA phylogenetic relationships and close sequence similarity within the Thermus genus. Under aerobic conditions, Thermus HR13 was capable of rapidly oxidizing inorganic As(III) to As(V). As(III) was oxidized at a rate approx...

The accessibility of histone H5 in chromatin was examined with monoclonal antibodies recognizing several epitopes of the globular region (GH5) of the histone (Rózalski, M., Lafleur, L., and Ruiz-Carrillo, A. (1985) J. Biol. Chem. 260, 14379-14385). The stoichiometry of the chromatin-antibody complexes indicated that while 0-86% of the H5 molecules were able to react, depending on the particular...

A novel thermo-alkali-stable catalase from Thermus brockianus was purified and characterized. The protein was purified from a T. brockianus cell extract in a three-step procedure that resulted in 65-fold purification to a specific activity of 5300 U/mg. The enzyme consisted of four identical subunits of 42.5 kDa as determined by SDS-PAGE and a total molecular mass measured by gel filtration of ...

Pink discoloration defects in cheese manifests as the appearance of pink patches within blocks and has recently been associated with Thermus thermophilus. Swiss-type cheeses were prepared at pilot scale using thermophilic starter cultures, Propionibacterium freudenreichii, one thermophilus HB27, scotoductus SE1 or DPC6866 a control without Thermus. Significantly, higher level redness was observ...
