Extraction and antioxidant activity of phenolic compounds from wheat bran treated by steam explosion
Purpose: To use response surface methodology to optimize the extraction of the phenolic compounds in wheat bran treated by steam explosion, and to determine the antioxidant activity of the extract obtained. Methods: By using response surface methodology, the effects of extraction time, methanol concentration, liquid/solid and temperature were studied and optimized. 2,2-Diphenyl-1-(2,4,6trinitro...
متن کاملAdsorption of Cadmium(ii) Ions from Aqueous Solution by Tectona Grandis L.f. (teak Leaves Powder)
Batch adsorption studies were undertaken with the abundantly available waste biosorbent Tectona grandis L.f. leaf powder for removal of cadmium(II) from aqueous solutions. The adsorption experiments were performed under various conditions such as time, temperature, different initial Cd(II) concentrations, pH, adsorbent dosage, and adsorbent particle size. The data showed that in 30 minutes, 1 g...
متن کاملAffinity precipitation of Aspergillus niger pectinase by microwave-treated alginate.
Affinity precipitation is a simple, single plate separation process in which the complex of a smart macroaffinity ligand with the target protein (from a crude broth) can be selectively precipitated by application of a suitable stimulus. Alginate is a copolymer of guluronic acid and mannuronic acid residues and precipitates with Ca(2+) ions. It was found to bind to pectinase present in a commerc...
متن کاملThe effect of wheat bran on the absorption and accumulation of cadmium in rats.
1. The major purpose of the present study was to determine whether the addition of wheat bran to endosperm crisp bread in a composite diet given to rats for 6 weeks causes an increase in the accumulation of cadmium in the rats due to the Cd content in the bran, or whether binding factors in the bran, such as dietary fibre and phytic acid, reduce or prevent the accumulation of this Cd. A second ...
متن کاملProduction of Clavulanic Acid by Streptomyces clavuligerus in Batch Cultures with Using Wheat Bran as the Source of Carbon
Nowadays Microbial biotechnology is considered as one of the most important and profitable branches of industry. In this approach, by using the generator microorganisms, We are able to produce biotechnological products, with higher efficiency. Clavulanic acid is being used in combination with commonly used beta-lactam antibiotics in order to fight against bacterial infections that are resistant...
