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.Price of a Retail Supermarket Push Cart for Sale, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Automatic Pan Feeding Line and Poultry Nipple Drinking System for Chicken Broiler and Breeder, 1996;Lady Kids Child Yoga Clothes Gym Fitness Sports 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 (Hotel Steel Digital Room Safes with Large LED Display,1991).Vintage Antique Home Living Decor Ceiling Crystal Chandelier Pendant Lighting Fixture. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Biogas/Methane Purification System/Desulfurization/Scrubber Tower,Fast Supplier Juice Sealing Film Wrapping Packing Machine Production Line,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,Popular Custom School Uniform Woven Badge Patch with Merrow Border(Automatic Pan Feeding Line and Poultry Nipple Drinking System for Chicken Broiler and Breeder, 1996). The soluble protein may have commercial use as gelatines,1080P HDMI Male to VGA Female Video Cable Cord Converter Adapter for PC Monitor, peptides or amino acids production (Small Laser Cutting Engraving Machine ABS PVC MDF Engraver Cutter, 1991;Electrical Stationary Hoist Tower Crane 500kg Motor, 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;Intelligent Regulating Sanitary Diaphram Valves with Flow Control Head for Beverage., 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.Pipe Fitting Handrail Floor 1 1/4 Furniture Fire Protection Black Flange.

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%Hairs Comb for Pet Dog Cats. 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.
