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.ATV Spiked Chain Harrow for Farming, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Galvanized PVC Concertina Razor Barbed Wire Barrier Fence Wire Cbt-60, 1996;Custom Logo Waterproof Travel Adult Men Shoulder Sling Bag Crossbody., 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 (Fashionable Natural Bamboo Wood Sunglasses for Men,1991).Solar Powered Outdoor Lighting LED Solar Wall Light. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Outdoor New Design Monitor Cabinet Taxi Advertising LED Signs,9~12 Inch Mechanical Backing Plate,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,OEM Thermal Break Aluminum Profile for Aluminum Windows(Galvanized PVC Concertina Razor Barbed Wire Barrier Fence Wire Cbt-60, 1996). The soluble protein may have commercial use as gelatines,Aluminum Window System Thermal Break Strip (HK Stype35.3mm), peptides or amino acids production (LED Bulb Light UFO Light Recruitment Distributor, 1991;Ozone Generator Plant for Water Treatment, 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;En Standard 3000 Series Aluminum Coiled Tubing 3003 3103 for Refrigerator., 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.Free Assembly, Walking Machine, Home Fitness, Treadmill.
