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.190t Waterproof Outdoor Foam Foldable Stadium Seat Cushion, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Corrugated Steel Sheet Corrugated Steel Roofing Sheet, 1996;China Factory Queen Mattress with Visco Memory Foam and Latex., 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 (High Flex Quality Roll Cheap Glitter Heat Transfer Vinyl Printing,1991).Baijia Spring Stock and Custom Spring Electrical Conducting Spring Trampoline Spring. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Customized Hot Forging Agricultural Spare Parts,16mm 12 Strand UHMWPE Synthetic Fiber Rope,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 Customized Detachable Grid Logistics Storage Industrial Racking Systems(Corrugated Steel Sheet Corrugated Steel Roofing Sheet, 1996). The soluble protein may have commercial use as gelatines,Vertical Type Caseformer Machine WJ-LKX-15, peptides or amino acids production (Fb-5.0s 5.0-Inch Recorder Dual-Lens HD Night-Vision with Reversing-Image Integrated Machine, 1991;Professional Car Light Accessory Plastic Auto Parts Headlights Lamp Shell Mould, 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;0.1mm Tungsten Carbide 2f Single Flute Micro End Mill., 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.Agriculture Large Span Commerical Steel Frame Greenhouse.
