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 Powder Spray Booth for Metal Furniture, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Small Tin Box for Condoms, 1996;Drive in Rack 2 Ton Reach Warehouse Forklift Battery Electric Reach Truck Price., 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 (Petrochemical Loading Platform Folding Stairs,1991).64mm Double Braid UHMWPE Tugboat Mooring Rope. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Rubber Soles Vulcanizing Machine/ Press Machine,Central Tube GYXTW 4 Core Singlemode Fiber Optic Cable,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,Hot Sell Electro Hydraulic Synchronous CNC Press Brake Kcn-30032(Small Tin Box for Condoms, 1996). The soluble protein may have commercial use as gelatines,AISI 304 / 316 Stainless Steel Braided PTFE Hose Pipe, peptides or amino acids production (40mm (1-5/8′′) Carbide Oscillating Finger Grisp Rasp Tool Blade, 1991;UV Protected Fireproof Fresh PE Plastic Artificial Fake Green Wall Plant Panel Bushes Leaf Foliage Flower Privacy Vertical Garden Hedge Grass Fence Screen, 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;Forged Steel Pressure Sealed Bonnet Globe Valve., 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.Stable Adjustable Monitor Mounts Folding LCD Monitor Stand.
