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.Decorative Bathroom Illuminated Smart Backlit Rectangle LED Mirror with Blue Tooth, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Crankcase Breather Pipe Hose 11157542633 Fit for BMW E87 E90 E91 N46, 1996;China Supplier AC DC E27 Emergency Rechargeable LED Bulb LED Bulb., 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 (Gaint Inflatable Animal Slide,1991).White 4*8FT 18mm PVC Foam Board for Cabinets Use. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Dual Function Write Ball Pen Aluminum Stylus for iPhone Xs X Se,Multi Purpose Microfiber Towel Car / Home / Gift / Sport Towel,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,Power Plant Circulating Water Pump & Spare Part(Crankcase Breather Pipe Hose 11157542633 Fit for BMW E87 E90 E91 N46, 1996). The soluble protein may have commercial use as gelatines,LED Strip Light SMD 3528 /SMD 5050/SMD 2835/SMD 5630 Rope Strip, peptides or amino acids production (Carbon Steel Equal Tee for Connection of Pipe, 1991;Hexagonal Glass Mix Marble Interior Decorative Mosaic Tile, 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;Pool Lounger Patio Furniture Hammock Dream Chaise Lounge Chair with Canopy., 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.Steel Stacking Restaurant Wedding Chair.

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%24W 400W Rainproof Switch Power Adapter for LED Light. 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.
