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 Solar Panel Solar Cell Photovoltaic 300W Hot Sell, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Vacuum Coating Machine Water Chiller (CW-6300AN), 1996;Planter Moving Round Planter Saucer Casters Plant Trolley (M)., 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 (1060 1100 3003 3105 5052 5005 Aluminium Coils Manufacturer in China,1991).Electric/Motorized Soft Seal Flanged Butterfly Valve (GAD941X). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom ABS&POM&PP&PC&Acrylic Plastic CNC Machining Turning Parts,CNC Machining Non-Standard Hardware Parts,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,DOT Aluminum Beverage CO2 Gas Cylinder 5lb 10lb 15lb 20lb(Vacuum Coating Machine Water Chiller (CW-6300AN), 1996). The soluble protein may have commercial use as gelatines,Galvanized Solar System Mounting Bracket Connector, peptides or amino acids production (Digital Programmable Ntc Temperature Controller, 1991;Water Meter Spare Parts Rubber Rings for Sealing, 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;Stainless Steel HK Series Needle Roller Bearing HK0408., 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.Road Construction Fabric Non-Woven Geotextile 200GSM.
