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.600000 BTU 700000BTU Tropical Central Rooftop Air Conditioner, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Nbm High Quality Auto Part Factory Price 6pk2310, 1996;Ultrasonic Automatic Face Mask Blank Making Machine., 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 (Manufacturer of Soda Ash Dense 99 2% Price,1991).Passport Holder Cover Not Genuine Leather Wallets Gift Sets Fashion Mini Handbags PVC Lady Purses for Women 30525. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Headband Big Headphone EVA Bag Tool Case Specialized Storage Box,Chicken Slaughtering Machine for Sale,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,750ml 700ml White Clear Wine Spirit Glass Bottles with Cork Stopper Finish(Nbm High Quality Auto Part Factory Price 6pk2310, 1996). The soluble protein may have commercial use as gelatines,Hf Vacuum Dryer Machine with Advanced High Frequency Technology, peptides or amino acids production (Wholesale Salon Products Hair Loss Treatment for Baldness Cotton Hair Building Fibers, 1991;Sunway 48V Solar Panel 500W 490W 460W Manufacturer China Whole Sell, 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;High Quality Wholesale Price Auto Iridium Spark Plug for Hyundai., 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.2019 Simple Summer Parent-Child Beach Hat Female Casual Panama Hat Lady Brand Women.
