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.280-350-500-550ml Glass Water Bottle with Sleeve (Customized Design Pattern), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (PS Foam Disposable Fast Food Box Making Machine, 1996;K Helical Bevel Gearboxes Reducer Motor., 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 (Indoor Customized Electronic Lighted LED Neon Open Sign,1991).Ecofriendly &Economic Jar Manufacture Cute Glass Handle Candy Jar. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fashion Buttons Clothing Accessories Eco-Friendly Nickel-Free Metal Blue Button,Custom Free Logo Design Cheap Hand Flag (NF01F02021),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,125kHz RFID Card 13.56MHz Proximity Card Blank Thin Card(PS Foam Disposable Fast Food Box Making Machine, 1996). The soluble protein may have commercial use as gelatines,Ultra Slim Crystal Seashell Design Shockproof Phone Cases for iPhone X, peptides or amino acids production (RJ45 Cat5e in-Line Coupler Modular Jack, 1991;Amazon Inserts Electric Fireplace with Gas Heaters Fan Modern Furniture, 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;Three-Dimensional 3D Fashion Design Wall Covering Material PVC Wallpaper., 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.Cold Rolled Coated Aluminum Coils 3003 H24 /1060/3004/5052.
