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.Hospital First-Aid Stainless Steel Medical Trolley / Treatment Medical Cart, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (SUS316 Hexagon Socket Set Screws with Cone Point, DIN914, 1996;Shantui SD32 Crawler Bulldozer with Three-Tooth Ripper for Sale., 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 (Airtac Type Pb Pneumatic Connector/ One Touch Air Conncetor,1991).Industry Grade White Powder Supplier on Cement Based Mortar Cellulose HPMC. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Explosion-Proof Housing Sealing Dispensing Machine,Tube Mills for Thin Wall Tubing,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,Corrosion Resistance HDPE Plastic Ball Valve PE100 Socket Joint Ball Valve with Steel Core(SUS316 Hexagon Socket Set Screws with Cone Point, DIN914, 1996). The soluble protein may have commercial use as gelatines,Car Badge Custom Emblem Auto Logo Sign for Advertising, peptides or amino acids production (2016 Hot Sale Excavator Furukawa Hb20g Hb30g Hb40g F35 F45 F50 Hydraulic Breaker Throught Bolt, 1991;Modern Office Ergonomic Executive Leather Swivel Office Chair (HC-Venlo), 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;Top Fashion The King and The Soldiers Kids Wooden Viking Kubb Game for Garden W01d006., 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.Rear Wheel Exchangeable Aluminum Manual Wheelchair.

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%360 Degree 3D Vr Panorama WiFi Bulb Camera (PST-VR20B1). 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.
