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.China OEM ABS Clear Plastic Injection Molding, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Widely Use 32 Cavities Pet Preform Water Bottle Mould, 1996;Black Powder Coated Steel Sheet Metal Housing., 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 (Alloy Steel Hot Forged 4140 42CrMo4 4340 Forging Ring,1991).Hot Sell 100% Seal Hexagon Glass Jam Jar. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Metal Parts Stamping, Stamped Brass Shrapnel,   Brass Connect Stamping, Electronic Connection Piece Metal Stamped Part, Copper, Brass Connect Stamping,High Quality Stacking Plastic Crystal Bar Stool Chiavari Napoloen Chair,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,Factory Direct Sale Custom Auto Refinish Paint Masking Tape/Crepe Paper Tape(Widely Use 32 Cavities Pet Preform Water Bottle Mould, 1996). The soluble protein may have commercial use as gelatines,Heavy Caliber Copper Rectangular Steel Tube, peptides or amino acids production (2mm White Coated Paper Cake Boards Jordan, 1991;Multiple Style Jewelry Packaging Box/Ring Box Custom Logo Jewelry Box, 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;Luxious Hotel Passenger Elevator, Titanium Elevator., 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.Yuchai 400kw Diesel Generator Set.

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%Air Cooled 2.8/3.0kw Single Phase Electric Start Portable Diesel Generator. 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.
