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.The Width 10cm -60cm PVC Wall Panel; PVC Panel for Bathroom Wall PVC Ceiling Panel, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Die-Casting Aluminium Radiator (RN808-500), 1996;Fr4 Double Sided PCB Fr4 PCB with Blue Solder Mask Custom Printed Circuit Board OEM with UL., 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 (Wholecut Oxford Plain Toe Black Antique Men Shoes,1991).New Technology Carbon Cleaning Tools Auto Accessories. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Environmental Test Salt Spray Tester Price,Custom 2 Ring Binder PP Lever Arch Clip File Folder,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,Quantum Science Lava Stone Pendant Necklaces Scalar Energy Pendant(Die-Casting Aluminium Radiator (RN808-500), 1996). The soluble protein may have commercial use as gelatines,TUV Approved Y Splitter 2 Way Solar Mc4 Y Branch Connector, peptides or amino acids production (CNC Laser Customized Telescopic Steel Cover, 1991;High Precision Mini Laser Cutting System, 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;Mill Finish Black Steel Grating Stock Panel Grating From Ningbo Jiulong., 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.1350ml Round Shape Borosilcate Lunch Box Office Used (GB13G17195).

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%Cosmetic Grade Matte Chromium Green Oxide for Cosmetics. 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.
