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.Metal Universal Vertical Turret Milling Machine (X6323 X6325 X6325D X6330), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Horizontal and Vertical Metal Universal Turret Milling Machine (X6325), 1996;4X8 Waterproof PVC Marble Sheet Wall Panels Decorative Bathroom Wall Panels., 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 (Vvvf Golden Mirror Sightseeing Passenger House Panoramic Home Observation Elevator,1991).PVC Cabinet Construction Board, White 18mm PVC Foam Board. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2019 New Portable Mini Dental X-ray Machine,Ss Reduced Port 2000wog 1PC Screwed Ball Valve,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,China Origin High Quality Food Grade Sodium Dihydrogen Citrate Anhydrous(High Quality Horizontal and Vertical Metal Universal Turret Milling Machine (X6325), 1996). The soluble protein may have commercial use as gelatines,China Prefab Steel Building for Garment Factory, peptides or amino acids production (Dark Blue Color Texture Indoor Swimming Pool Glass Mosaic Tile, 1991;Cable Tray with ′t′ Slots, 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;10 Gauge Galvanized Welded Wire Mesh for Construction Using., 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.High Quality Factory Inline Hockey Skate Puck.

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%24V Ultrasonic Fogger 100mL Aroma Diffuser 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.
