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.New Arrival Wooden Kids Cleaning Set Toy for Education W10d251, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Vertical Type Automatic Box Erector Machine, 1996;Air Cooled Scroll Type Water Chiller for Industrial Process., 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 (Pn6.3 8 10 16 3 4 5 Inch Water Supply Pipe and Plumbing Conduits Fittings Unplasticized Polyvinyl Chloride Pipes for Potable Cold Water Supplies China,1991).Auto Part Front Brake Disc for Fortuner Kun51 2005-2012 43512-0K090. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Rotary Vibrating Sieve Machine for Compost,I9s Tws Wireless Earphone Portable Bluetooth Headset Earbud,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,Sachets Powder Coffee Stick Powder Bag Salt Packaging Packing Machine(Vertical Type Automatic Box Erector Machine, 1996). The soluble protein may have commercial use as gelatines,Chengli Manufacturer 20000L LPG Refilling Skid with LPG Dispenrser for Africa, peptides or amino acids production (Modern Carbon Fiber Bathroom Vanity Combo with Mirror Cabinet, 1991;Multifunctional Stainless Steel Mesh Filter Cylinder Punched Round Hole Shape Filter Tube, 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;Condoms/Sex Toys/Capsule Toy Vending Machine., 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.Abstract Decorative Oil Wall Paintings on Ultra Clear Low Iron Glass (MR-YB6-2046B).
