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.Activated Alumina Used for Catalyst Carrier in Chemical Industry, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality 45W 50W Commercial Recessed COB LED Downlight, 1996;Toyo-Ta Denso 4 Pin Female Wire Harness Ignition Coil Plug Connector., 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 (1.25gbps SFP Optical Fiber Transceiver LC Connector 1310nm 20km (PHY-8525-1LS),1991).Automatic Liquid Juice Stick Sachet Ice Lolly Pop Packing Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Steel Structure Polycarbonate Greenhouse Builder and Contractor and Manufacturer,High Speed Auto Corrugated Carton Box Paperboard Production Line,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,Custom Waterproof BNC Connector for Industry(High Quality 45W 50W Commercial Recessed COB LED Downlight, 1996). The soluble protein may have commercial use as gelatines,Indoor Inkjet Media Material, peptides or amino acids production (Steel Jacket Steam Insulation Pipeline Production Famouse in China, 1991;Solid Steel Hotel Safe (G-42BD classics) for Hotel, 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;Sany Excavator Pn. 11340981 Monitor for Hydraulic Excavator Sy335c/Sy365c/Sy335c., 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.CNC Aluminum Alloy Metal Stamping Processing Services.

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%Bgf-800 BOPP Dry Laminating 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.
