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.High Quality CO2 Laser Marking Machine with Ce, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (New Design Inclined Plane 18W LED Wall Washer Lighting, 1996;2ton R Type Electric Wire Rope Hoist with Single Speed., 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 (Stainless Steel Body Infrared Burner Good Selling Gas Stove,1991).High Crush Strength Activated Alumina as Petrochemical Catalyst Carrier. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Adhesive CAS 9003-35-4 Phenolic Resin,Household Kitchen Cleaning Tools Aluminum Handle Cotton Dust Control Mop,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,Manufacture Best Choice Liquid Flocculant for Ink Removal(New Design Inclined Plane 18W LED Wall Washer Lighting, 1996). The soluble protein may have commercial use as gelatines,Hot Dipped Galvanized Oval Wire Brazil, peptides or amino acids production (Colorful Pet Natural Tough TPR Rubber Toy Cat Dog Chew Toys, 1991;Wood Grain Embossed Film for Flooring, Flower Design Film, Wood Grain Heat Transfer Polyester Film, Pet Heat Transfer Film, 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;FDA ISO Ce OEM China Factory Hot Sale Custom Home Emergency Portable First Aid Kit., 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.Custom Fashion Cup Mat Silicone Rubber Coaster for Tea- Best Housewarming Beverage, Drink Silicone PVC Coaster Beer Drink Coaster Cup Coaster (YB-CC-1).
