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.Copy Paper Writing Paper Newspaper Toilet Paper Tissue Paper Kraft Paper A3A4 Paper Corrugated Paper Facial Paper White Board Paper Wrapping Paper Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Colorful 100% Cotton Hotel Face Towels, 1996;High Quality Electric Folding or Curving Bender 3D CNC Hydraulic Bneder Automatic Pipe Bending Machine Used for Furniture and Chairs (GM-SB-76CNC-2A-1S)., 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 (33kv Dry Type Resin Casted Distribution Transformer,1991).Huaxia PAR56 Color Changing Swimming Pool Light Bulb LED Fixture Pool Used E27 Compatible with E26 with Remote Control Hx-PAR56-E27. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Economic and Reliable P32 Hydraulic Hose Crimping Machine Italy with SGS Certificate,Size 000 Clear Pullulan Vegetarian Capsules,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,Sinicline 2018 Hot Sell Custom Printing Thank You Cards(Colorful 100% Cotton Hotel Face Towels, 1996). The soluble protein may have commercial use as gelatines,Black Red Open Net Spandex Nylon Sexy Lingerie, peptides or amino acids production (7W Aluminum Waterproof LED Lawn Light Use for Garden Lighting, 1991;Jforall Liquid Water Oil Tank Pipe High Accuracy Side Top Mount Level Monitor Switch Capacitive Sensor, 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;LED Emergency Exit Lights., 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.Dn40 ISO Awwa ASME Remote Control Pneumatic Cast Iron Steel SS304 SS316 Center Line Wafer Butterfly Valve.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,External Retaining Ring for Shaft, DIN471, D1400.

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%Good Use Kitchen Stainless Steel Spiral Scrubbing Scourer / Pot Scrubber. 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.
