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

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%ABC-508 Brake System Cleaning and Fluid Exchanging Machine. 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.

CONCLUSIONS

Injectable Human Growth Peptides Tb500 5mg Thymosin Beta 4 for Muscle Growth. Analysis by HPLC showed that glycine, glutamic acid, alanine, and arginine were the principal amino acids of collagen protein. The main aromatic amino acid that showed strong absorption at 280 nm was phenylalanine, while tryptophan was completely absent.
