Biochemistry of civet coffee fermentation in the digestive tract civets until now is not fully known. This study aims to isolation, characterization and identification bacteria molecularly from civet's tract. Analysis begins with surgery obtain fluid three parts Isolation conducted by pour plate method using nutrient agar media. Single different colonies (shape, colour, margin, elevation, size)...

Molecular vegetable breeding has been progressed intensively in recent years. Huge advances have made germplasm evaluation, gene isolation, plant transformation, editing and molecular-marker-assisted breeding. The goal of this Special Issue is to highlight, through selected works, frontier research from basic applied molecular papers published Horticulturae exhibit a diversity listed editorial ...

The lysozyme gene has been purified by molecular cloning from two chicken gene libraries. Several recombinant phages harbouring sequences homologous to a plasmid carrying a double stranded lysozyme cDNA have been isolated. One recombinant appears to carry an entire lysozyme gene. Electron microscopic studies show that the latter is split by at least three introns. The length of the gene is abou...

conclusions this paper may serve as a guide to screening, isolation, and cultivation of more new mtb. the new isolated strain opens up good opportunities for biotechnological applications such as medicine to bioremediation processes due to its unique abilities. results the results revealed a correlation of important physicochemical factors such as ph and iron with growth and blooms of these bac...

A general method of gene isolation has been developed that involves the chemical linkage of RNA to cellulose by a water-soluble carbodiimide, and the continuous circulation of DNA containing specific sequences complementary to the RNA. The temperature of the cellulose matrix is maintained at 37 degrees (50% formamide, 0.3 M NaCl-0.03 M Na(3) citrate) to allow efficient DNA-RNA interaction in th...

Understanding how speciation can take place in the presence of homogenizing gene flow remains a major challenge in evolutionary biology. In the early stages of ecological speciation, reproductive isolation between populations occupying different habitats is expected to be concentrated around genes for local adaptation. These genomic regions will show high divergence while gene exchange in other...

we describe a rapid, simple, and reliable procedure for routine isolation of mycobacterium leprae dna from slit-skin swab specimens. this one-step dna extraction method is based on the utilization of chelexr 100, a chelating ion exchange resin. slit-skin swab specimens from seven untreated leprosy patients at baba baghi leprosy hospital in iran were processed by this procedure. the polymerase c...

When grown under anaerobic conditions, Neisseria gonorrhoeae, the etiologic agent of the sexually transmitted disease gonorrhea, expresses several novel outer membrane proteins. One of these, Pan 1, has an apparent molecular mass of 54 kDa in electrophoresis and is recognized by serum samples from patients with gonococcal infection. The presence of antibodies to this protein in patient sera sug...

Nocardiae are Gram-positive, filamentous, aerobic, relatively slow-growing, and weakly acid-fast bacteria which cause nocardiosis in humans. We describe a 53-year-old patient with chronic bronchitis referred to Al-Zahra Hospital, Isfahan. A bronchial washing sample was taken from the patient. A Nocardia-like microorganism was detected in microscopic evaluation. Based on the phenotypic and 16S r...

We describe reproductive isolation caused by a gene transposition. In certain Drosophila melanogaster-D. simulans hybrids, hybrid male sterility is caused by the lack of a single-copy gene essential for male fertility, JYAlpha. This gene is located on the fourth chromosome of D. melanogaster but on the third chromosome of D. simulans. Genomic and molecular analyses show that JYAlpha transposed ...
