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.Customized Stainless Steel Sheet Metal Cabinet Fabrication Electrical Cabinet, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Construction Material Hoist Rack and Pinion, 1996;3000lb Small Boat Marine Electric Trailer Winch Power-in, Power-out., 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 (Utl Supply Phoenix Contact Cage Clamp Dinrail Terminal Blocks,1991).Diamond Circular Tct Saw Blade for Cutting Wood/Marble Stone/Metal. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2018 Classic New Design Metal Optical Glasses Men and Women Reading Eyeglasses,High Quality Endoscopic Surgical Adult Disposable Bite Block,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,China OEM ABS Clear Plastic Injection Molding(Construction Material Hoist Rack and Pinion, 1996). The soluble protein may have commercial use as gelatines,Widely Use 32 Cavities Pet Preform Water Bottle Mould, peptides or amino acids production (Black Powder Coated Steel Sheet Metal Housing, 1991;Alloy Steel Hot Forged 4140 42CrMo4 4340 Forging Ring, 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;Hot Sell 100% Seal Hexagon Glass Jam Jar., 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.Metal Parts Stamping, Stamped Brass Shrapnel,   Brass Connect Stamping, Electronic Connection Piece Metal Stamped Part, Copper, Brass Connect Stamping.

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%M23 Round Plug 9 12 Pin Male MID Fixed Signal Connector. 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.
