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.Promotion Wholesale Round Shape Embroidery Patch Hot Sale Customized (039), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Deck Crane Electro-Hydraulic Telescopic Boom Remote Control Operation, 1996;Dust Hood Fume Extraction Systems for Robotic Laser Cutting., 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 (IP40 M8/M12/M16/M23 Male Waterproof Cable Circular Industryconnector,1991).Nordic Solid Wood Dining Chair/Smile Chair. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Factory Direct Sale Industrial Strong Double Sided Tape with Foam or Pet,Experienced and Professional Plastic Helmet Mold Manufacturer,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,Private Label OEM Best Cute Waterproof Lip Pluming Gloss(Deck Crane Electro-Hydraulic Telescopic Boom Remote Control Operation, 1996). The soluble protein may have commercial use as gelatines,Single Touch Saw Touch Screen 23.6′′ Touch Screen LCD Display, peptides or amino acids production (Good Excellent Rubber Yoga Mat Making Machine / Rubber Tile Making Machine/Rubber Floor Press, 1991;High Quality 10W iPhone Case Laptop Metal Sheet LED Laser Printing Marking Machine, 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;IN-505 Cheap ABS Plastic Medical Filing Drawers Bedside Cabinet., 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.Tent Windows Use China Made PVC Transparent Clear Mesh Tarp.
