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.Premium quality for Potassium Humate powder, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wedding Cake Knife Serving Set Stainless Steel Acrylic Handle, 1996;Home Design Solid Wood Double Adult Bed Bedroom Furniture., 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 (Epon ONU with 4ge 2VoIP Pots 2.4G 5g Twon Antenna WiFi Gepon Ont,1991).High Quality Dental Primary Molar Crown Stainless Steel Kids Crowns. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,304 Precision Professional Dimpled Stainless Steel Plate,Boundry Wall Powder Coated Galvanized Welded Double Wire Mesh Fence,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,Outdoor High Bay Luminaire Fixture 240W 200W 150W 100W 60W Industrial UFO LED High Bay Light(Wedding Cake Knife Serving Set Stainless Steel Acrylic Handle, 1996). The soluble protein may have commercial use as gelatines,Stainless Steel Vertical Pipe Clamp Cast Iron Machinery Joint Flexible Shaft Coupling, peptides or amino acids production (Prefabricated Steel Framed Sheds to Metro, Railway Station, Underground Carport, Airport, 1991;Special Shape Spring with Good Quality and Fast Delivery, 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;Better Quality White Coated Fbb Paper Ivory Board., 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.Excellent Plastic Extruder in Pet PP Packing Strap Machine.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%Captain Woodwork Sanding Machine/Sanding Table. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.
