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.High Quality Plastic Injection Mold Parts Square Interlocks Maker, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (LED Outdoor Solar Lawn Garden Lighting for Wall, 1996;3-Pin Australia Power Cord Plug with SAA., 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 (Sludge Oil Separation Centrifuge,1991).8011 Aluminum Foil for Cap Used. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Pepper Peanut Sauce Colliod Miller Grinding Machine,Gasoline Rototiller, Cultivator, Tiller Model Gtm-6,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,12.5mva Transformer 12500kVA 33kv 35kv Power Transformer(LED Outdoor Solar Lawn Garden Lighting for Wall, 1996). The soluble protein may have commercial use as gelatines,Electronic Foldable for Patient Treatment Ent Unit Chair, peptides or amino acids production (Plastic Pushbutton Ultrasonic Spin Welding Machine, 1991;500ml 1000ml Juice Drinking Beverage Glass Swing Top Bottle Bottles, 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;Double Shaft Paper Cardboard Waste Plastic Shredder Machine., 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.Paintcolor Brand Spray Booth Leading Manufacturer of Paint Spray Chamber for Over 15 Years with Highest Quality Standards.
