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.Interlocking Precast Plastic Concrete Paver Molds for Sale, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (24K Gold EGF Serum Capsule Anti-Wrinkle Repairing Anti Aging Serum, 1996;900-1800MHz GSM PCB Antenna, 3m Adhesive GSM Built-in PCB Antenna., 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 (Best Price 1.4507/S32550/Alloy 2507 Stainless Steel Pipe,1991).Plastic Flange Housing Ucf310-115 for Electric Hand Tools. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Two Sided Lighted Vanity Mirror Folding 1X and 5X or 10X LED Makeup Mirrors,Yangtze 12V 100ah Lithium Ion 10kw Solar Recharge Battery,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,Fabric Coated PVC for Garment Woven Fabric 600d 100% Polyester(24K Gold EGF Serum Capsule Anti-Wrinkle Repairing Anti Aging Serum, 1996). The soluble protein may have commercial use as gelatines,Tct Circular Saw Blade &Diamond Saw Blade, peptides or amino acids production (Low Voltage Mediu Voltage Cable PVC Flexible Control Cable with Braided Shield Cable, 1991;Lifting Thread with Needle for Plastic Surgery, 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;Methyl Cyclohexane Methylcyclohexane, Organic Chemicsls., 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.LiFePO4 Prismatic Pouch Cell 3.2V 10/20/30/40/50/100ah Flat LiFePO Lithium Battery for Electric Car.
