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.Custom Printing A5 Elastic Bandage Leather Notebook with Emboss Logo School Notepad, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wholesale New Fashion Leather Bag Lady Handbag Crossbody Bag, 1996;Positive Drive Turn Belt for Spiral Freezing Equipment., 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 (Chinese Herb Medicine Angelica Root Extract,1991).S Series China Generator Helical-Worm Crushers Reduction Box. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Chinese Knuckle Boom Hydraulic Truck Mounted Crane for Sale,Original Testo 174t Mini Temperature Data Logger No. 0572 1560,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,Domestic and Industrial Wastewater Treatment Plant Mbr/Waste Water Treatment Plant/Water(Wholesale New Fashion Leather Bag Lady Handbag Crossbody Bag, 1996). The soluble protein may have commercial use as gelatines,Hot Sale Factory stainless Steel Dining Chair OEM Dining Furniture, peptides or amino acids production (New Style Fashion Custom Branded Printing Sublimation Plain Summer Merino Wool Cotton Bamboo Polyester Leisure Quick Dry Undershirt Slim Fit Long Sleeve T-Shirt, 1991;Whole Set Gas Spring Strut for Furniture, 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;Dia. 5.5mm Bonding ND: YAG Laser Rod Lens., 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.CNC Machining Turning Anodized Aluminum Worm Gear.
