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.Jqx-59f Wholesale Operate Time 25ms 12V Power Relay for Energy-Saving, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Singlemode Su Upc Fiber Optic Fast Connector, 1996;Roller Skating Sneakers Shoes for Children (8083)., 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 (Food Grade Beer/Juice Treatment Bag Mamachine SUS304 316L Stainless Steel Bag Filter Vessel with Ss Removable Frame Holder,1991).Electric Heating Industrial Jacketed Glass Reactor. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,40X-1600X Biological Microscope Xsz-107V LED Light,6063 Aluminum Coil for Commercial Vehicle Floor,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,Silicon Carbide Foundry Porous Ceramic Foam Filter(Singlemode Su Upc Fiber Optic Fast Connector, 1996). The soluble protein may have commercial use as gelatines,1200X1000X810 Strong Collapsible Plastic Containers for Storage, peptides or amino acids production (Steel Construction in Poultry House with Good Quality and Installation, 1991;Surface Mounted LED T5 Linear Batten Lamp 0.6m 7W with Switch 3000K Warm White, 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;10PCS/ Box Golden Silver Fishing Sequins Metal Lure Tackle., 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.Stone Cracking Rock Cutting Cement.
