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.Ld-Zg002 Special Corrosion and Scale Inhibitor for Chemical Plant, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Aluminum Mould Shoe Mould Making CNC Milling Router Machine, 1996;High Pressure Fitting Quick Coupling Hydraulic Plug., 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 (High Quality Products Insulin Syringe/ Insulin Pump with Medical Head Cover,1991).Refrigeration Digital Temperature Controller Stc-100A. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Boston Round 50ml Refillable Plastic Pet Cosmetic Perfume Mist Spray Bottle,Women Cow Leather Handbag Genuine Leather Shoulder Bag for Ladies,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,Black Color Hexagon Bolt with High Quality(Aluminum Mould Shoe Mould Making CNC Milling Router Machine, 1996). The soluble protein may have commercial use as gelatines,China Supplier! ! ! Hot Sale 16mn Galvanized Steel Pipes, peptides or amino acids production (Afen Auto Opened Door Pasta Sexy Toys Auto Vending Machine with Competitive Price, 1991;Fengdeng Wholesale Multi-Functional Fashion Mummy Baby Diaper Backpack Bag, 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;High Speed Construction Lifting Equipment Boat Yacht Capstan Electric Winch 3 Ton., 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.Back Adhesive 72W Solar Flexible PV Laminate Panels (PVL-72).

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%Mini Car Portable Fridge 10L Mini Fridge. 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.
