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.Eco-Friendly Summer Beach Lady Handmade Paper Shopping Straw Basket Bag, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (304 304L 904L 309S 310S Stainless Steel Design Checkered Plate, 1996;High Quality 0.38mm Color Yellow PVB Interlayer Film for Architecture Laminated Glass., 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 (2017 Factory Directly Oversized Women Sunglasses,1991).High Quanlity PTFE Thread Seal Tape. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fiberglass Grating, FRP Grating, GRP Grating,Aluminium Profile Roller Shutters OEM/Rolling Screen Aluminium,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,Rutile Titanium Dioxide Exterior Emulsion Paint(304 304L 904L 309S 310S Stainless Steel Design Checkered Plate, 1996). The soluble protein may have commercial use as gelatines,Promotional Multi-Function CO2 CNC Control Table Laser Cutter Engraving Supplier, peptides or amino acids production (Cheap CNC Plasma Cutter for Sale with Flame CNC Steel Sheet Cutting Machine for Round Tube Cutting Manufacturer Factory Plasma Cutting Machines, 1991;Stainless Steel Hole Punching Machine/ CNC Perforation Machine, 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;Rockwool Insulation Pipe for Bolier with Aluminum Foil Steam Tube., 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.Pet and PP Geobag with UV High Strength Thermal.
