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.Smallest Portable Waste Transformer Oil Purifier Machine Zy-6, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Sale 5ml Portable Pocket Sized Travel Refillable Aluminum Perfume Atomizer Spray Bottles, 1996;High Speed Automatic Packing Machine (GK-650 BA)., 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 (5000-5900MHz 4G Built-in Automotive Antenna,1991).Glass Lined Reactor for Chemical Factory. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,OEM Metal Stamping Stainless Steel Parts with CNC Machining,Tropical Custom Clear Christmas Poly Mailers Bag Mailing Envelopes for Paper,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,Supermarket Plastic T-Wire Basket Swing up Price Label Holder(Hot Sale 5ml Portable Pocket Sized Travel Refillable Aluminum Perfume Atomizer Spray Bottles, 1996). The soluble protein may have commercial use as gelatines,1kg 2kg 3kg Coffee Bean Roasting Machines Coffee Bean Drum Roaster Machine, peptides or amino acids production (Latest Lady Thick Outsole Slippers PU Upper Summer Shoes Yx0627-7, 1991;Heat Exchanger Sheet Boile Water Pipe Carbon Steel Seamless Pipe, 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;Degradable PLA Plastic Bottle., 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.Wholesale China Merchandise 12V Horizontal Mini Camping Fridge.

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%Superior Watertightness JS Polymer Cement Waterproof Coating for Basement. 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.
