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.Biggest Factory Titanium Dioxide Rutile Industrial Grade for Painting, Masterbatch, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Aluminum Insulating Ceramic Fiber Paper for Industrial Kilns, 1996;Pet Laminate Aluminium Foil/Pet+Alu+PE., 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 (6 Ton Mini Excavator Wheel Digger Machine with Rotation Hydraulic Gapple Factory Directly Sale,1991).New Design Multi-Color Silicone Coin Purse for Lady. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Common Rail Injector Control Valve F00rj01451 for 0445120064/074/136/137/424/363/362/246/234/139/074/138/065,Portable Folding Table for Camping, Picnic, Outdoor, Family Party Form Camping Kitchen,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,Dark Green Plastic PVC Film for Christmas Tree Leaves(High Aluminum Insulating Ceramic Fiber Paper for Industrial Kilns, 1996). The soluble protein may have commercial use as gelatines,Desktop 3-Axis Automatic Fluid Dispensing Machine with Case and Monitor, peptides or amino acids production (Pure Peptide Powder PT-141 for Enhancing Male Power with GMP (ODM), 1991;1X4mm2 (12AWG) Solar Cable Red or Black PV Cable Wire Copper Conductor XLPE Jacket TUV Certifiction, 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;Water Treatment Anthracite., 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.Heat Treated Welding Protection Glassfiber Cloth Ht800.
