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.Whole Set Gas Spring Strut for Furniture, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Dia. 5.5mm Bonding ND: YAG Laser Rod Lens, 1996;CNC Machining Turning Anodized Aluminum Worm Gear., 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 (China Solar Panel Solar Cell Photovoltaic 300W Hot Sell,1991).Vacuum Coating Machine Water Chiller (CW-6300AN). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Planter Moving Round Planter Saucer Casters Plant Trolley (M),1060 1100 3003 3105 5052 5005 Aluminium Coils Manufacturer in China,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,Electric/Motorized Soft Seal Flanged Butterfly Valve (GAD941X)(Dia. 5.5mm Bonding ND: YAG Laser Rod Lens, 1996). The soluble protein may have commercial use as gelatines,Custom ABS&POM&PP&PC&Acrylic Plastic CNC Machining Turning Parts, peptides or amino acids production (CNC Machining Non-Standard Hardware Parts, 1991;DOT Aluminum Beverage CO2 Gas Cylinder 5lb 10lb 15lb 20lb, 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;Galvanized Solar System Mounting Bracket Connector., 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.Digital Programmable Ntc Temperature Controller.
