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.20m3/H Wet Mix Concrete Mixer Machine Mobile Concrete Batching Plant, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (304 321 310 310S Welded Decorative Stainless Steel Pipe, 1996;Hot Sale! ! ! Bearing 608 Ceramic Deep Groove Ball Bearing (608ZZ/RS)., 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 (Manual Electric Winch Small Winch 220V Winch,1991).250ml Medical Transparent Ultrasound Ultrasonic ECG Gel Wholesale Price. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Kitchen Condiment Bottles Spice Seasoning Salt Pepper Grinder Storage Jar,Plastic PVC Business Credit Card Fresnel Lens Magnifier Hw-805A,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,Good Quality Low Price 18mm Natural Ash Veneer Fancy Plywood(304 321 310 310S Welded Decorative Stainless Steel Pipe, 1996). The soluble protein may have commercial use as gelatines,Metal Stamping Bending Sheet Metal Fabrication for CNC Machinery Part, peptides or amino acids production (Aluminum Plate Fin Heat Exchanger/Oil Cooler Core, 1991;3X Desk Clip-on Magnifying Glass Lamp LED Light PCB Inspection, 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;3mm/0.21mm Aluminum Cladding Building Material Aluminum Composite Plastic Sheet., 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.5-Axis CNC Machining Billet Aluminum Engine Rotary Housing.

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%Best Price of Peanut Digger / Groundnut Harvester in Australian Africa. 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.
