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.Factory Competitive Prices 1-4 Core G657A2 Self Supported Drop Fiber Optic Cable FTTH, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Cast Iron Flooring Strong Corrosion Resistant Pig Flooring, 1996;STPP Sodium Tripolyphosphate for Detergent / Ceramic / Food., 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 (100ml/120ml/125ml Glass Bottle for Whisky/ Brandy/Rum/Wine,1991).New Styles Fashion Erotic Women Underwear Sexy Lingerie. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Quality 1530 Metal Cutting Cheap CNC Plasma Pipe Cutting Machine with Rotary,Custom Precision Sheet Metal Forming Bending Welding Parts Housing Stamping,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,200 Tons Press Brake 4000mm CNC Press Brake 200 Tons Hydraulic Press Brake with Bending 8mm(High Quality Cast Iron Flooring Strong Corrosion Resistant Pig Flooring, 1996). The soluble protein may have commercial use as gelatines,Fully Automatic Water Bottle Lids Labeling Machine, peptides or amino acids production (2u Lgx Swing out Fiber Optic Patch Panel with 4 SC Simplex Single Mode Adapter Panels, 1991;New CCTV 4.0MP H. 265+ IR Bullet Waterproof IP Camera, 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;Non-Woven Anti-Static Briefs...Non-Woven Anti Static Briefs., 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.Fused Silica Quartz Lump 5-50mm for Refractory Materials.

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%Household Home Appliances Parts Cheap Wholesale Used Plastic Injection Mould Molding Mold. 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.
