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.Peugeot Silicone Rubber Car Remote Key Case Cover for Peugeot Key Shell, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (3 Layer Round Tea Tin with Air Tight Lid, 1996;China PA System Power Amplifier with Enough Rated Power., 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 (Export Grade Citric Acid Monohydrate as Detergent,1991).Queen′s Jewelry Fashion 316L Stainless Steel Silver Crown Pendant Necklace. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Familu Use Mini Small Pig Feed Pellet Mill,3D LED Motif Outdoor Lighted Star Christmas Shopping Mall Decorations Light,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,Construction Chemicals Raw Material Sodium Lignosulphonate for Cement Plasticizer(3 Layer Round Tea Tin with Air Tight Lid, 1996). The soluble protein may have commercial use as gelatines,Yellow Color PVC Film for Bags Raincoat Inflatable Toys Water-Bed, peptides or amino acids production (Hairdressing Equipment Takara Belmont Barber Chair High Quality, 1991;Full Auto Stand up Pouch Forming Filling and Packing Machine (HMK-2000), 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;Buy Single Item Moving Bee Eye Light Lowly Price., 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.High Quality Customized Aluminum Foil Shisha Sheet.
