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.China Superior Quality Soya Protein Food Production Machine Line, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ocrown Holographic Dark Blue Glitter Flakes Decoration Supplier, 1996;Custom Army Style 100% Polyester Fiber Mens Polo Shirt., 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 (E2000/APC Connector Type Plug-in Female to Male Fixed Fiber Optic Attenuator,1991).Twisted Annealed Wire for Binding. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Wholesale Pyrex Heating Water Bottle Cold with Stainless Steel Lid,Wholesale Fashion Jewellery Lady Eardrop Earrings for Women,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 Cheap Small Metal Hard Guide Way Flat Bed Horizontal CNC Lathe Machine Ck0640(Ocrown Holographic Dark Blue Glitter Flakes Decoration Supplier, 1996). The soluble protein may have commercial use as gelatines,Yuhuan Manufacturer Hydraulic Fittings Quick Connection Pipe Fittings Hose Fittings, peptides or amino acids production (Full Automatic AAC Concrete Lightweight Block Making Machine, 1991;Stainless Steel CF8/CF8m Street Elbow Pipe Fittings, 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;Pure Epitalon Peptide 50mg Powder Epitalon for Bodybuilding., 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.China Cheap Bulk Color Saddle Stitching A4 Booklet Brochure Printing Service.
