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.Ghrp-2 Building Muscle Pharmaceutical Peptide 5mg/Vial 99.80% High Purity From Lab Supply, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Density Celuca Kitchen Cabinets PVC Foam Board, 1996;2mm Mirror Glass/Coated Glass for LED, LCD, Computer Screen etc., 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 (E171 Standrad Titanium Dioxide Food Grade A200,1991).Elbow Forming Machine Gorelocker HVAC Duct Making Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Stainless Steel Barbecue Net BBQ Grill Grates Wire Mesh,Best Selling Colorful Branded Custom Logo Polarized Sunglasses Women Men 2018 Fashion UV400 Cat3 Mirrored Sun Shade Glasses,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,L Shape U Shape Big Corner Home Villa Living Room Hotel Lobby Full Chinese Italy Leather with Manual Movable Headrest Confortable Sofa Set Furniture(High Density Celuca Kitchen Cabinets PVC Foam Board, 1996). The soluble protein may have commercial use as gelatines,460g Good Tensile Strength PU Fiberglass Thermal Insulation Fabric, peptides or amino acids production (304 Stainless Steel Anti-Corrosion Welded Wire Mesh, 1991;Custom Made Colorful Sublimation Womens Yoga Pants Wholesale, 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;Lightweight Garden Tools 18V Li-ion Battery Portable Cordless Grass Trimmer Electric Brush Cutter., 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.Outdoor Garden Lamp Remote Control with Polycrystalline Silicon Solar Panel.

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%Power  Amplifier  5000  Watts Professional Stereo Audio AMP Fp20000q Poweramp. 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.
