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.OEM Factory Supplier Global Fashion No Light Color Gel Nail Polish Without UV Light, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Shingles Wholesale Building Material Roofing Materials Spanish Sheet Roofing Tiles, 1996;Natural Latex Pocket Coil Spring Mattress for 5 Star Hotel., 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 (Flex Rigid Printed Circuit Board with UL Flex PCB for Electronic Products,1991).Made in China Lqa Strap Banding Tool. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New R&D Wire Cable Feeding Winding Machine,Stainless Steel Manual Glass Kitchen Ajustable Pepper with Low Price,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,Residence Use 220V 50Hz 12kw Portable silent Diesel Generator(Shingles Wholesale Building Material Roofing Materials Spanish Sheet Roofing Tiles, 1996). The soluble protein may have commercial use as gelatines,Garden Decoration Marble Stone Granite Small Angel Sculpture Water Fountain, peptides or amino acids production (530ml Glassware/Glass Jar/Wine Bottle/Liquor Bottle/Spirits Bottle/Glass Vodka Bottle, 1991;PCB Connector Pin Connector 1.0 Pitch Dual Row Pin Header, 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;Sdlg LG936L Wheel Loader Spare Parts 4041000687 Hose Assembly., 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.Galvanized Roller Shutter Window Torsion Springs.
