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.Top Grade 93% High Purity 5L Flow Home Use Medical Portable Oxygen Concentrator Generator, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Outdoor Portable Charcoal BBQ Grill Barbecue Camping Stove, 1996;CZ300 Automatic Switching Galvanized Plate C Z Purlin Roll Forming Machine., 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 (Small Portable Air Water Purifier with Disinfection and Detoxification,1991).Fog Smoke Machine 1500W for LED Moving Head Beam Light DMX. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,1850mm*80mm Stable Power Laser Tube,White Color Premium Quality Disposable Plastic PVC Apron,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,Galvanized Bar Grating(Outdoor Portable Charcoal BBQ Grill Barbecue Camping Stove, 1996). The soluble protein may have commercial use as gelatines,Ring Die Bio Organic Fertilizer Pellet Mill Machine, peptides or amino acids production (Hot Dipped Galvanized Deer Fence From Factory, 1991;High-Quality Glass Prp Tubes Centrifuge Kit Blood Collection Tube with Ce, 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;Tire Rubber Powder Recycling Equipment for Sale Truck Tires Rubber Shredding Facility., 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.Cheap Customized Aluminium Sand Casting.
