RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.

INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Plastic Clear T-Shirt Retail Drinks Tea Coffee Coca Beverage Bags, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Oscillating Knife Cutting Machine EVA/Foam/Cardboard Cutter Plotter, 1996;Printing Pure Color Women Fitness Wear., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Butterfly Pn16 CF8m Water Dual Flap Flapper Type Wafer Check Valve,1991).Polypropylene Strapping Band Production Line/PP Strap Making Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,China Suppliers Plastic Vacuum Blister Packaging Machine with Servo Motor,12V Battery Power DC Mini Air Pump for Sphygmomanometer Dqb370-B,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,500ml Blue Glass Beer Bottle with Crown Cap(Oscillating Knife Cutting Machine EVA/Foam/Cardboard Cutter Plotter, 1996). The soluble protein may have commercial use as gelatines,White Iron Wear Crusher Blades 63HRC, peptides or amino acids production (Inclined Plate Sedimentation Tank Lamella Clarifier with Chemical Dosing System, 1991;Stone Carving Flower Pot for Garden Decoration, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;2018 New Fashion Men Canvas Messenger Bag., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.High Purity Sodium Bicarbonate with White Powder Type.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%2017 Year The Newest 7inch LCD Screen Advertising Brochure Video Greeting Cards. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
