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.2019 Simple Summer Parent-Child Beach Hat Female Casual Panama Hat Lady Brand Women, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Tonva New Design Harpic Bottle Making Extrusion Blow/Blowing Molding Machine, 1996;Oak Laminate Grey Floating Cork Vinyl Plank Flooring., 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 (China Manufacturer Customized Microwave Ring Ferrite Magnet,1991).Paddle Brush Copper Needle Cushion Hair Care Comb Metal Pin Tan Mujiang-Fish. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Competitive Price Good Quality Custom Unisex Marle Grey Fleece Hoody,Printing Adhesive Waterproof Custom Membrane Switch for Electric Cooker,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,Electrical 4W AC Synchronous Gear Motor for Engraving Machine(Tonva New Design Harpic Bottle Making Extrusion Blow/Blowing Molding Machine, 1996). The soluble protein may have commercial use as gelatines,Custom Car Seat Belt Buckle Mold Maker, peptides or amino acids production (DIN/ANSI/JIS/API Stainless Steel CF8/CF8m Wafer Type Butterfly Valve for Pn10/Pn16 or 10K/16K or Class150/300/600 for Sanitaty/Oil/Gas/Water, 1991;Exfoliating Shower Hemp Bath Sponge Pad, 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;Real Gold or Imitation Golden Color PVD Vacuum Plasma Ion Coating Machine for Watch, Jewelry., 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.Wireless Optical Fire Smoke Detector with Solar Powered (ES-T601).

The final soluble protein shown were used for peptides separations using gel permeation chromatography,1.75mm 3mm ABS PLA PC 3D Printer Filament Machine.

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%Korea Technology Commercial Waterproof Eco Click Lock Luxury Vinyl PVC Plank Flooring. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
