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 Indoor Light Linear Light Aluminium LED Profile, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (50g 100g Small Sachet Vegetable Seed Sunflower Seeds Packing Machine Price, 1996;Graphic 240X128 Dots Monochrome LCD Display Module., 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 (Dry & Wet Concrete Surface Metal Grinding Wing,1991).Workbench Anti-Static Table ESD Natural Rubber Table Mat. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,316L 10 Micron Sintered Stainless Steel Filter Disc,Underground Mining Material Handling Belt Conveyor Trough Idler Roller Support/Frame/Bracket,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,Abstract Light and Shadow Metal Oil Painting for Deco(50g 100g Small Sachet Vegetable Seed Sunflower Seeds Packing Machine Price, 1996). The soluble protein may have commercial use as gelatines,Silo Machine Equipment for Chicken Farm Feed Use (JF-A-L003), peptides or amino acids production (Cheapest Container Living House/Office/Kiosk, 1991;Spin Centrifugal Demister Separator or Column Internal, 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;Baby Wet Wipe 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.Closed Impeller Centrifugal Pump Mining Pit Diesel Engine Drive Pump.

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%Polypropylene Fibre for Commercial Slabs. 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.
