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.Hot Sale Classic Golden Painted Rectangular Mirrored Dining Table, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (52cc Gasoline Paddy Cutter Two Handle, 1996;Horizontal Heavy Duty High Pressure Multistage Centrifugal Water Pump., 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 (Durable Fully Automatic Hot Dipped Anti-Rust Galvanized Vertical Type Wire Mesh Steel Metal Baby Chicks Breeding Cage,1991).OEM Viton Mechanical Rubber Oil Seal. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Rapid Prototype Plastic Molding Simple Rapid Tooling and Simple Mould,Dicalcium Phosphate 18% Granular DCP 18% Feed Grade Animal Nutrition Feed Additives,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,China Manufacturer PVC Layflat Hose, High Pressure Lay Flat Hose for Industrial Discharge(52cc Gasoline Paddy Cutter Two Handle, 1996). The soluble protein may have commercial use as gelatines,400-600 Grit 201 304 Grade Polished Stainless Steel Pipe, peptides or amino acids production (Meanwell LRS-35-24 35W 24V 1.5A Merchanical And Electrical Equipment With 3 Years Warranty Switching Power Supply, 1991;Wholesale 10kg 25kg Raschel Sacks for Packaging Vegetables, 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;5 Axis CNC Machining Part Clear Anodize High Precision 3D Horizontal Scanner Extension Adjusting Nut., 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.Variable 50Hz 22kw AC Drive 3 Phase Frequency Inverter.
