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.Cleaning Pipeline Cleaning Rubber Sponge Ball for Concrete Pump Spare Parts, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ivd Component PP Barbed Threaded Connector, 1996;Workshop Tools 7.5 Ton Electric Winch with Dual Speed., 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 High Energy 1500mj 1064nm 532nm Painless Permanent Age Spot Freckle Tattoo Removal Skin Laser Therapy Equipment,1991).Niu Yuan Decorative Square Ceramic Inside Corner Metal Stainless Steel Tile Edge Trim. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,500ml Stainless Steel Thermos Glass Sport Flask Vacuum Kettle Double Wall Water Bottle,RFID Blocking Leather Slim Zipper Credit Card Holder Wallet,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,2017 New Design Vinyl 3D Stone Wallpaper Factory in China(Ivd Component PP Barbed Threaded Connector, 1996). The soluble protein may have commercial use as gelatines,Custom Small Paper Gift Box with Magnet Closure for E-Cigarette, peptides or amino acids production (Agricultural Mini Tiller Farm Wheel 62cc Cultivator, 1991;0.8 Ton New China Small Hydraulic Bucket Crawler Mini Bagger Excavator with Cheap Factory Price, 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;Antique Brown Marble Mosaic Tile for Floor/Wall/Bathroom/Backsplash/Table/Patterns., 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.High Efficient Online Hot Glue Dispensing Machine for Electronic Products.
