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.Nail Art Drawing UV Spider Metal Gel Acrylic Lace String Painting Gel Supply, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Handheld Andriod POS with Thermal Printer, 1996;Stainless Steel French Earring Hook for Jewelry., 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 (Professional Metal Stamping Parts with Anodizing,1991).Agriculture Indoor Vegetables and Fruits Planting Greenhouse. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Night Vision Wide HD Waterproof Car Side View Camera for Bus,Kukai 2019 New Version China High Security Sec-E9 Key Cutting Machine Free Upgrade,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,5 Micron Big Blue 10 X 4.5 Pleated Washable Sediment Water Filter(Handheld Andriod POS with Thermal Printer, 1996). The soluble protein may have commercial use as gelatines,E2000/APC Fibre Optic Leads and Cables, peptides or amino acids production (Plastic PVC Wire Making Extrusion Machinery for Building BVV Cable, 1991;Physical Foaming Wire Extruder, 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;Business Men Soft Genuine Leather Wallet Credit Card RFID NFC Blocking Card Holder Protective Case Fold Style Safe Protector Holder., 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.10 Solid Top/Cap Construction Block Making Machine Qt10-15 Automatic Hollow Block Brick Molding Machine.
