The results of a series of experiments are presented which demonstrate that the absorption of UV-C light by DNA at temperatures below the melting temperature leads to complete and reversible denaturing for small synthetic DNA of 25 base pairs (bp), and to partial and reversible denaturing for the 48 bp DNA and for the large salmon sperm and yeast DNA of average size 100 kbp. This result support...

The rhizosphere is the area around the root of a plant occupied by a unique population of usefulbacteria known as plant growth promoting rhizobacteria (PGPR). In this study, the isolation andidentification of rhizobacteria from orange (Citrus sinensis) orchards using 16S rRNA gene, as well asbiological and biochemical assays is reported. Analysis of 16S rRNA gene was confirmed bybiological and ...

Micellar-enhanced ultrafiltration (MEUF) was used to remove phenol from simulant aqueous solutions. The effect of groups difference of cationic surfactant on the solubilization of phenol was investigated through orthogonal experiment, namely, surfactants with the same length of hydrocarbon chain but different hydrophilic head group and vice versa. The effects on the solubilization of

Acylphosphatase is expressed in vertebrates as two molecular forms, the organ common and the muscle types. The former does not contain cysteine residues, whereas the latter contains a single conserved cysteine (Cys-21). We demonstrated that H(2)O(2) at micromolar levels induces, in vitro, the formation of a disulfide dimer of muscle acylphosphatase, which displays properties differing from thos...

The deoxyribonucleic acid (DNA) of Escherichia coli B is converted by colicin E2 to products soluble in cold trichloroacetic acid; we show that this DNA degradation (hereafter termed solubilization) is subject to inhibition by infection with bacteriophage T4. At least two modes of inhibition may be differentiated on the basis of their sensitivity to chloramphenicol. The following observations o...

Obtaining homogeneous population of natively folded RNAs is a crippling problem encountered when preparing RNAs for structural or enzymatic studies. Most of the traditional methods that are employed to prepare large quantities of RNAs involve procedures that partially denature the RNA. Here, we present a simple strategy using 'click' chemistry to couple biotin to a 'caged' photocleavable (PC) g...
