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.Popular Custom School Uniform Woven Badge Patch with Merrow Border, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (1080P HDMI Male to VGA Female Video Cable Cord Converter Adapter for PC Monitor, 1996;Small Laser Cutting Engraving Machine ABS PVC MDF Engraver Cutter., 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 (Electrical Stationary Hoist Tower Crane 500kg Motor,1991).Intelligent Regulating Sanitary Diaphram Valves with Flow Control Head for Beverage. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Pipe Fitting Handrail Floor 1 1/4 Furniture Fire Protection Black Flange,Cermet Circular Cold Saw Blade for Carbon Steels Cutting with Special Tooth Feature,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,Flow Wrapper/ Bakery Moon Cake Packing Machine(1080P HDMI Male to VGA Female Video Cable Cord Converter Adapter for PC Monitor, 1996). The soluble protein may have commercial use as gelatines,Full Automatic Liquid Filling; Machine; Oil Detergent Shampoo Disinfectant Bleaching Liquid Soap Cleaner Corrosive Filling Capping Labeling; Packing Machine, peptides or amino acids production (Roll-up Heat Resistant Aluminum Mosquito Net 24X24 Window Screen Cover Wire Mesh, 1991;Reusable Metal Stainless Steel Drinking Straws, 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;Designed Steel Frame Factory Building., 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.Detergent and Cosmetic Grade SLES/AES Sodium Lauryl Ether Sulfate.

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%Bus Diesel Engine Parts 1105-00058 Fuel Filter for Yutong Zk6129h. 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.
