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.Produce N2o for Medical Gas Equipments, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Selling Furring Channel Fittings Suspended Ceiling Accessories, 1996;90m3 Per Hour Mobile Concrete Pump., 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 (China High Quality CATV FTTH 1550 Nm External Modulated Optical Transmitter,1991).FTTB Wdm Optical Receiver with 2 Output / AGC FTTB Optical Node. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,All Weather Rattan Handwoven Swing Outdoor Home,Pond Self Priming Booster suction  Water Pump with Pressure Switch,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,Digtal Camera for Sewer Line Inspection System with Self Level and Meter Counter(Hot Selling Furring Channel Fittings Suspended Ceiling Accessories, 1996). The soluble protein may have commercial use as gelatines,Modern Furniture Brick Finishing Wood Fireplace Mantel Surround Electric Fireplace, peptides or amino acids production (for Wall Decoration Glass Silver Metal Aluminium Mosaic Tile, 1991;100% Polyester Gabardine Shirting Fabric with Transfer PrintingTree, 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;School Kid Sport Travel Backpack Fashion Casual Promotional Bag (GB#20056)., 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.Fuguang High Quality Fb1015-280 280ml Double Wall Glass Water Bottle.

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%Frame Type Rubber Hydraulic Press 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.
