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.Air Cooled 2.8/3.0kw Single Phase Electric Start Portable Diesel Generator, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Commercial Vegetable Mushroom Coconut Meat Drying Machine, 1996;4mm/5mm/6mm/8mm/10mm/12mm/15mm/19mm Tempered Glass/Flat and Curved Glass/Safety Glass., 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 (Headband Big Headphone EVA Bag Tool Case Specialized Storage Box,1991).Hydraulic Fold-Bend Machine Hydraulic Bending Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Delphi Control Valve 28239295 (622B),OEM Precision Aluminum Alloy/Zinc Alloy Die Casting,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 Sale Ink Chip for Epson P6070/P7070/P8070/P9070 Inkjet Printers(Commercial Vegetable Mushroom Coconut Meat Drying Machine, 1996). The soluble protein may have commercial use as gelatines,Bathroom Makeup LED Mirror Glass with Light, peptides or amino acids production (Green PVC Coated Euro Fence Welded Wire Mesh Fence Garden Fence Euro Wire Fence, 1991;Hot Selling Mini 3D Printer 80mm/S Ender-3 PRO Cheap 3D, 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;White and Green Board, School Writing Board, School Furniture (GT-76C)., 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.Current Precise LED Digital Ammeter.

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%High Density Insulation Rock Wool Board for Wall. 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.
