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.Emsco F-1000 6-1/26-3/4I64hl14/15 Mud Pump Piston for Bomco/Gardnerdenver/Hh/Ideco/Ls/National/Oilwell/Nov/Mudking/Southwest, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (3.2m Vertical Wheelchair Elevator Platform for Sale, 1996;LC Multistage Pump Mechanical Seal (KLLC)., 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 (Wedding Tent Cooling System Outdoor Event Air-Con Units,1991).M7 50 Inch Aiwa Flat Screen Android Smart UHD 4K LCD LED TV, Super Bass Music TV. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Opal Lens LED Strip Light Aluminum Profile/Extrusion Channel,Prime Gi Steel Strip Galvanized Metal Strip Price,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,Fireproof Aluminum Curtain Wall Panel(3.2m Vertical Wheelchair Elevator Platform for Sale, 1996). The soluble protein may have commercial use as gelatines,Fast Delivery Malleable Iron Pipe Fitting Hexagon Nipple, peptides or amino acids production (High Quality Perfume Cosmetic Empty Eye Cream Lotion Oil Press Dropper Bottles Wholesale 10ml 15ml, 1991;China OEM 94V0 Single-Sided Ceramic PCB Prototype Multilayer Ceramic Printed Circuit Board, 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;Adjustable Grooming Table., 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.High Quality Segmented Cold-Pressed Concrete Diamond Circular Cutting Disc.

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%2400mm Wood Pulp Waste Paper Corrugated Paper Machine Kraft Liner Paper Making Machine. 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.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
