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.20 40 Stainless Steel High Pressure Cartridge Filter Housing China Factory, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Tefude Feeding and Packaging Line for Food with Tray, 1996;Aluminum Alloy Front Control Panel Machining Monitoring Linear Combination 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 (Automatic Sawdust/Rice Husk/Biomass Pellet Making Machine,1991).CMP No Nc Metal Switch Black 25mm Illuminated Push Button. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fashion Design Camo Men′s Outdoor Camouflage Cotton Crew Socks, Printed Socks,Full Hard S550gd Cold Rolled Galvanzied Steel Sheet in Coil,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,Felt Disc Polishing Sanding Disc with Wool Felt Diam(Tefude Feeding and Packaging Line for Food with Tray, 1996). The soluble protein may have commercial use as gelatines,13.56MHz Contactless RFID Card MIFARE 1K Card for Prepaid Payment System, peptides or amino acids production (Thermomolded TPE 5X20mm IP68 10K Air Conditioner Probe Black Cable, 1991;100% Fiberglass 1*1m Fire Blanket 3732 Fiberglass Cloth, 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;240T goodeng water/oil/gas pipe drilling rig HDD 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.Mens Messenger Bag 15.6 Inch Waterproof Waxed Canvas.

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%Indoor UTP Cat 6 with Rj 45 Connector Length 20 Meter Cable. 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.
