spasmolytic, antioxidant, anti-inflammatory and immuno-modulatory properties of ginger (rhizome of zingiber officinale roscoe) suggest that it may has beneficial effects on inflammatory bowel diseases. in the present study, the effect of this herbal extract on a model of acute colitis was evaluated. ginger hydroalcoholic extract with doses of 150, 350, 700 mg/kg, prednisolone (2 mg/kg), or vehi...

conclusions it can be concluded that the rsm is an effective method for the optimization of recombinant protein expression using synthetic genes in e. coli. results the proposed optimum fermentation condition consisted of 7.81 g l-1 glucose, od 600 nm prior induction 1.66 and induction temperature of 30.27°c. the model prediction of 0.267 g l-1 of rhifn-β and 0.961 g l-1 of acetate at the optim...

in this research, the accelerated ripening of the kabkab dates from khalal to tamr using nacl and acetic acid solutions was studied. fruits at khalal stage were harvested and washed with distilled water before being treated with ripening inducers: 1. nacl solutions, 2. acetic acid solutions and 3. aqueous solution of nacl (1%) and acetic acid. moisture, ph, colour, brix and textural firmness of...

Levels of free D-amino acids were compared in 11 vinegars produced from different sources or through different manufacturing processes. To analyze the D- and L-amino acids, the enantiomers were initially converted into diastereomers using pre-column derivatization with o-phthaldialdehyde plus N-acethyl-L-cysteine or N-tert-butyloxycarbonyl-L-cysteine. This was followed by separation of the resu...

A critical factor in ensuring the safety of acidified foods is the establishment of a thermal process that assures the destruction of acid-resistant vegetative pathogenic and spoilage bacteria. For acidified foods such as dressings and mayonnaises with pH values of 3.5 or higher, the high water phase acidity (acetic acid of 1.5 to 2.5% or higher) can contribute to lethality, but there is a lack...

abstract balanced nutrition and soil organic mater are among most important factors affecting yield and quality of grape (vitis vinifera cv.peykani). humic acid as an organic acid derived from humus and other organic sources, in accompany with zinc, and acetic acid can reduce deficiency symptoms in grape. to study the effects of zinc, humic acid and acetic acid on yield and yield components, an...

Organic apple cider vinegar is produced from apples that go through very restricted treatment in orchard. During the first stage of the process, the sugars from apples are fermented by yeasts to cider. The produced ethanol is used as a substrate by acetic acid bacteria in a second separated bioprocess. In both, the organic and conventional apple cider vinegars the ethanol oxidation to acetic ac...

Antisera were raised in rabbits with acid-treated Re mutant bacteria from Salmonella minnesota and Escherichia coli and tested in a passive hemolysis assay with di- and monophosphorylated free lipid A of E. coli (LipA-Ac and LipA-HCl, respectively) coated onto sheep erythrocytes. Depending on the acid used to prepare the immunogen (acetic versus hydrochloric acid), different antibody specificit...

Ready-to-eat meats are considered foods at high risk to cause life-threatening Listeria monocytogenes infections. This study screened 5 L. monocytogenes strains for their ability to hydrolyze sinigrin (a glucosinolate in Oriental mustard), which formed allyl isothiocyanate (AITC) and reduced L. monocytogenes viability on inoculated vacuum-packed, cooked, cured roast chicken slices at 4 °C. Test...

indole acetic acid is an important hormone that improved the growth of different plant organs such as the root under normal and stress conditions. as various studies have shown, most of rhizobacteria produce indole acetic acid and thereby contribute to the growth of plants. in this study, different rhizobacteria were isolated from different regions of iran for the assessment of their ability to...
