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.Colored Silicone NBR O-Rings Seals, Rubber O Ring with High Strength, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Reinforced Stainless Steel 306L Wire Wrap Johnson Type Strainer Screen, 1996;Colorful Braided Fabric Cable Round., 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 (Universal Wholesale Hot Sale Custom Blank Keys,1991).Latex Free Olive Face Cut Makeup Sponge /Oval Makeup Sponge Not Makeup Remover Sponge. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Rotary Automatic Wet Wipe Production Linewet Wipes Machine RM-Wl30,Waw 8 Ton Logistics Light Truck for Transportation,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 Forging Lathe Spindle Forged Spindle(Reinforced Stainless Steel 306L Wire Wrap Johnson Type Strainer Screen, 1996). The soluble protein may have commercial use as gelatines,Hot Sale Chic Straw Braid Floppy Hat with Print Tape, peptides or amino acids production (High Quality Plastic Butterfly Valve UPVC DIN ANSI JIS Standard Wafer Worm Gear Butterfly Valve PVC Level Butterfly Valve for Water Supply, 1991;Lamella Clarifier in Sewage Tretament Plant for Water Purification, 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;BMC (DMC) / SMC Compression Moulding., 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.Ring Caps &Plastic Tube Pop Novelties.
