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.China Supplier Granular Coal Based Activated Carbon Filter Meida, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Glass Cutting Table/CNC Glass Cutting Machine, 1996;12 Bottles Portable Home Ues Thermoelectric Wine Chiller., 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 (Ss 304 316L Sintered Ss Filter Sinter Stainless Steel Mesh Filter for Liquid Diesel Oil Treatment Filter,1991).Portable Mini USB Charging Flashlight 10W T6 LED Flashlight (SYSG-190321). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Brushed Cotton Twill Fine 3D Embroidery Custom Baseball Cap,Robotic Fastening Tool/Desktop 4-Axis Screw Fastening Robot  /Instead of Manual Fastening,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,Wholesale Logo Printed Recycled Retail Paper Shopping Bag with Handle(Glass Cutting Table/CNC Glass Cutting Machine, 1996). The soluble protein may have commercial use as gelatines,Black Plastic Drain Pipe Underground Direct Factory Price HDPE Pipe for Water Supply Large Diameter Plastic Pipe, peptides or amino acids production (Stainless Steel Coil Heat Exchanger Industrial Water Cooler Stainless Steel Heat Exchanger, 1991;Stainless Steel SS304 SS316L Sanitary Hygienic Air Vent Valve, 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;Q35y-30 Ironworker Shearing and Punching Machine Ce Approved Q35y Hydraulic Iron., 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.Shenzhen Yizexin Numeric Keyboard Conductive Ink Membrane Switch.

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%Industrial Laundry Ozone Generator for Jeans, Linen and Gray Cloth Bleaching. 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.
