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.Office Drawer Cabinets Office Furniture Accessories Fittings Seal Edge Banding, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Men′s Leather Loafers Shoes Driving Loafer Men Dress Shoes, 1996;High Quality Spooling Pet Polyester Mylar Film for Cable Material., 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 (Irrigation Hydroponics System Planting Tools Film Greenhouse for Agriculture/ Farming,1991).Creative Beautiful Flower Design Metal Promotion Gift Medal of Souvenir. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2019 High Quality 12V 3.1A Quick Charge QC 3.0 Phone Charger 2 USB Port Car Charger Custom Logo,Unique Design for Handle Champange Glass Uesd for Hotel and Restaurant,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,150mm Interior Decorative WPC Ceiling Tiles PVC Wall Panels(Men′s Leather Loafers Shoes Driving Loafer Men Dress Shoes, 1996). The soluble protein may have commercial use as gelatines,Best Design and Nice Price All in One Solar Street Light, peptides or amino acids production (Customized Large Ss Stamping/ Bending Sheet Metal Parts, 1991;High-Quality 201 304 410 430 Grade Mirror Finish Stainless Steel Sheet, 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;UV Laser Marking Machine (with Air Cooling System)., 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.Energy Saving Street Light E27 E40 27W LED Corn Bulb.

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%New Invention 2017 Male & Female Stainless Steel Quick Coupling. 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.
