Feasibility of using dot blot hybridization to detect Salmonella InvA, SpiC and SipC directly from clinical specimens

  Pathogenesis of Salmonella depends upon a large number of factors controlled by an array of genes that synergise into actual virulence. The goal of this study was to detectSalmonella invA, spiC and sipC directly from clinical specimens, using the dot blot hybridization assay. We detected invA, spiC and sipC as a one combination from 4.5% (95% CI:...

Increasing the bioethanol yield in the presence of furfural via mutation of a native strain of Saccharomyces cerevisiae

  High ethanol yield is a desired property of industrial yeast strains. A significant problem in fermentative conversion of lignocellulosic materials to ethanol is the formation of furfural and hydroxymethylfurfural (HMF), which are formed during acid hydrolysis of lignocellulose. Furfural has been known to create strong inhibition in metabolism of the yeast Saccharomyces cerevisiae. In this article,...

Continuous butyric acid production by corn stalk immobilized Clostridium thermobutyricum cells

  Corn stalks were used as a support to immobilize Clostridium thermobutyricum in a fermentation process for butyric acid production. The effects of pH and acetic acid concentration on butyric acid production were examined in a steady-state 25-day continuous flow operation. A metabolic shift was induced by changing pH of the medium. The maximum and the minimum ratio of butyric acid and acetic acid...

Antibiotic drug resistance of hospital acquired Staphylococcus aureus in Andra Pradesh: A monitoring study

  Nosocomial infections are one of the occupational biohazards that affect the health of individuals with or without predisposing factors. Staphylococcus aureus is associated with significantly higher mortality and is associated with community-acquired serious nosocomial infections because strains generally show multiple drug resistance, which limits treatment possibilities. A total of 1800 patients...
