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.1.75mm 3mm ABS PLA PC 3D Printer Filament Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Korea Technology Commercial Waterproof Eco Click Lock Luxury Vinyl PVC Plank Flooring, 1996;Nutrition Enhancer Environmental Nutritional Yeast Powder., 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 (Decor Paper Laminate Wood Flooring Manufacturer Also Wood Grain Design for 8mm 12.3mm Laminated Flooring,1991).CO2 Glass Tube Ss Laser Marking Machine for Different Non Metal Marking Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New Technology P8 Outdoor LED Display Screen Videowall for Propaganda Board,Best Selling Anti-Aging Remover Hyaluronidase Injection Hyaluronic Acid Lyase,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,High Quality Army Captain Navy Blue Color Hat for Army Tender(Korea Technology Commercial Waterproof Eco Click Lock Luxury Vinyl PVC Plank Flooring, 1996). The soluble protein may have commercial use as gelatines,Women′s Tote Bag Small Canvas Shoulder Bag Daily Working Handbag, peptides or amino acids production (High Efficiency Mini-Pleat HEPA Filter (H13/H14), 1991;Modern Vertica Parking Garage System, 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;Wholesale Price of Citalopram Hydrobromide Powder Sample Packing for Test., 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.Galfan Wire (Aluminium-Zinc Alloy coated).
