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.8FT Wood Log Debarker Machine for Plywood Machinery, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Fryer Equipment Potato Chip Banana Chips Frying Production Line Snack Food Processing French Fries Making Machine, 1996;Honkon 2019 New Arrival 4D High Intensity Focused Ultrasound Skin Care Medical Beauty Machine., 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 (High Density Graphite Crucible for Melting Metal,1991).Hydraulic Press Corrugated Cold Roll Automatically Forming Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Empty Vodka Glass Bottles 500 Ml Alchohol Glass Bottles for Wine,Medical Supplier Non Woven 3ply Earloop Disposable Face Mask,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,UHP Shp HP Graphite Electrode for Smelting Diameter 350mm 400mm 450mm for Steel Mills, Block, Powder, Mould(Fryer Equipment Potato Chip Banana Chips Frying Production Line Snack Food Processing French Fries Making Machine, 1996). The soluble protein may have commercial use as gelatines,Interlocking Anti-Fatigue Kitchen Rubber Mat, Kitchen Floor Mat, peptides or amino acids production (High Quality Large Military Adhesive Laser Embroidery Scout Patch Velcro Back (087), 1991;LG-42- L1+L2+R1+R2, LG 42 Ln, 42′ LG LED TV Backlight Strips/Bars/Spears, Small Lens, 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;Psa Oxygen Generator Plant Used Hospital with Oxygen Cylinder Filling 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.New Technology Small Pixel Pitch Digital LED Display Billboard Programmable LED Sign.

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%High Performance Alcohol Pad Making 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.
