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.CE Certificated Wheel Loader (HQ912) with Agricultural Tire, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Sale Custom Made Sublimation Printing Women Polyester Gym Shorts, 1996;PPGI/PPGL Corrugated Steel Roofing Sheet for New Building Construction Material., 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 (Cold Rolled 0.3-3mm 310 310S Stainless Steel Sheet,1991).Rd 10 Portable Air Operated Double Stainless Steel Diaphragm Pump. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,ASTM Tp316 304 201 Square/Round Galvanized Stainless Steel Pipe for Chemical, Aerospace Equipment,Komatsu Shantui Shehwa Zoomlion Liugong Dozer Steering Valve (16Y-76-22000 144-40-00100),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,Custom Black and White Segment Code Screen Electronic Scale LCD LCD Screen Digital Display Electronic Scale Dedicated LCD Screen(Hot Sale Custom Made Sublimation Printing Women Polyester Gym Shorts, 1996). The soluble protein may have commercial use as gelatines,DIN7504 Stainless Steel Pan Head Philips Self Drilling Screw, peptides or amino acids production (Auto Two Piece Folder Gluer for Corrugated Box, 1991;British Standard 2 Gang 1 Way Wall Light Switch, 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;Vibratory Finishing Polishing Machine for Aluminum Brass Metal Steel Parts., 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.Commercial Fitness Gym Strength Equipment Half Rack Body Solid Power Cage.

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%4000W Industrial High Power Pipe Plate Whole Cover Exchange Platform Metal Fiber Laser Cutter for Carbon/Aluminum/Stainless/Brass 3015gr. 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.
