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.Bolts and Nuts Set Brass Fasteners Double Hex Bolt, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Direct Sales Kids Boy Cotton Children T Shirt, 1996;Strong Electric Locksmith Lock Pick Gun Tools for Bump Door Lock Opener., 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 (15/16/17/18/19/20 Inch Factory Direct Supply Car Alloy Wheels for Audi,1991).Light Blue PVC Plastic Sheet and PVC Film. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Dentist Used Metal Dental Steel Nickel Chrome with Beryllium Alloy,Metric Female Cone Hydraulic Hose Fitting,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,Hot Sale Dental Material Dental PMMA Block From China(Factory Direct Sales Kids Boy Cotton Children T Shirt, 1996). The soluble protein may have commercial use as gelatines,Plastic Waste Pet Flakes Recycling Washing Machine, peptides or amino acids production (Deposited Stainless Steel Rivet Nut with Knurled, 1991;High Quality Stainless Steel Mechanical Filter Hosing, 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;Paper New Year Greeting Cards Wedding Invitations Cards., 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.Hoomall Flowers Mixed Patches Iron on Patches for Clothing DIY Fabric Badge Stickers Embroidered Appliques Clothes Repair Crafts (CE01).

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%2019 Good Price Screw Press Sludge Dewatering Machine for STP ETP Wwtp Cetp/Water/Waste Water/Sewage/Effluent Treatment. 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.
