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.Automotive Rubber Parts for Any Rubber Material, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Die Casting Zinc Alloy Badge Use for Car, 1996;Hair Twist Sponge Hair Brush Twist Hair Sponge Barber Hair Brush Sponge., 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 (CREE Chip 24W 28W 30W LED Downlight,1991).Stone PVC Luxury Vinyl Plank Spc Flooring with V Groove. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Three Phase 35kv Current Transformer for Indoor,China Shipping Logistics to Stockholm,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,CNC Lathe Main Parts with Good Quality(Die Casting Zinc Alloy Badge Use for Car, 1996). The soluble protein may have commercial use as gelatines,Good Price High Torque 12mm Low Speed Small Geared Motor, peptides or amino acids production (Custom Small Size 4.3 Inch LCD Screen TFT Panel Display for Video Brochure Advertising Player Invitation Greeting Card, 1991;Fashion PU Rhombic Style Crossbody Bag Waist Bag for Woman and Man, 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;Waterproof 100W 100 Watt LED Flood Light for Tennis Court Lighting., 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.Chemical HPMC Kraft Paper Bag with PP Woven Fabric Laminated.
