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.Manufacturer of Soda Ash Dense 99 2% Price, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Passport Holder Cover Not Genuine Leather Wallets Gift Sets Fashion Mini Handbags PVC Lady Purses for Women 30525, 1996;Headband Big Headphone EVA Bag Tool Case Specialized Storage Box., 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 (Chicken Slaughtering Machine for Sale,1991).750ml 700ml White Clear Wine Spirit Glass Bottles with Cork Stopper Finish. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Hf Vacuum Dryer Machine with Advanced High Frequency Technology,Wholesale Salon Products Hair Loss Treatment for Baldness Cotton Hair Building Fibers,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,Sunway 48V Solar Panel 500W 490W 460W Manufacturer China Whole Sell(Passport Holder Cover Not Genuine Leather Wallets Gift Sets Fashion Mini Handbags PVC Lady Purses for Women 30525, 1996). The soluble protein may have commercial use as gelatines,High Quality Wholesale Price Auto Iridium Spark Plug for Hyundai, peptides or amino acids production (2019 Simple Summer Parent-Child Beach Hat Female Casual Panama Hat Lady Brand Women, 1991;Tonva New Design Harpic Bottle Making Extrusion Blow/Blowing Molding Machine, 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;Oak Laminate Grey Floating Cork Vinyl Plank Flooring., 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.China Manufacturer Customized Microwave Ring Ferrite Magnet.

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%Customized Length Medical Suction Connecting Tube with Yankauer Handle Crowed/Standard Tip. 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.
