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.LED Assembly Wave Soldering Machine Price, SMT Machine Wave Soldering, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (PE Jacket Sm G652D 12 Fibers Armored Fiber Optic Cable, 1996;3D CAD Engineering Metal High Precision Auto Parts CNC Machining Parts., 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 (Original Brand New Classical Small Mobile Phone for Nokia E52 Cell Phone,1991).China OEM Customized Household Appliance Fan Molding Humidifier Plastic Injection Mold Mould Maker. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Stainless Steel Fruit Seed Extractor Fruit Seed Remove Machine Passion Fruit Pulping Machine,4G Body Worn Camera Ambarella IP67 Frame Rate 1080P@30fps/720p@30fps,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,Best Price Aluminium Sulphate for Water Treatment(PE Jacket Sm G652D 12 Fibers Armored Fiber Optic Cable, 1996). The soluble protein may have commercial use as gelatines,Hot Sale Loading Truck with Cummins Engine, peptides or amino acids production (Solid Surface Lowes Bathroom Countertops/Acrylic Solid Surface Sheets, 1991;50kg Soya Bean Seed PP Woven Bags Sacks, 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;Iron Wire Dry Type Straight Line Wire Drawing Machine., 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.Guangzhou Canton Fair Foshan Furniture Market Aluminium Furniture Profile.

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%Good Quality Banded Type Tee. 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.
