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.OEM SS304 Stainless Steel Sw Reducing Tee for Food Machinery, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Best Sale 30W 60W 80W 100W 120W LED Intelligent High Power All in One Integrated Solar Lamp Street Light with Light Sensor and Motion Sensor, 1996;High Quality Bucket Segment Bolt 6V0937., 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 (Best Price Hollow Section Ms ERW Welded Black Steel Pipe for Furniture,1991).Outdoor Server Rack Network Data Cabinet. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Dedi 43′′ 55′′ Outdoor LCD Display Screen with Camera,Flat Prefab Shipping Container Home Prefabricated Modular Pack Movable House,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,High Quality HDMI to VGA Converter Cable with Audio and USB Power Cable(Best Sale 30W 60W 80W 100W 120W LED Intelligent High Power All in One Integrated Solar Lamp Street Light with Light Sensor and Motion Sensor, 1996). The soluble protein may have commercial use as gelatines,Hub 113-27-41330 for Bulldozer D31p-18 Spare Parts, peptides or amino acids production (OEM Light-Weight Aluminium Die Casting Casing Parts for Auto Parts, 1991;Carbon Steel Pipe ASTM A106 A53, 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;Reasonable Price 1715 1708 Aluminium LED Strip Profile for Hotel., 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.Peptides Powder Ghrp 2 for Muscle Building with Super Quality.
