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.High Quality Mini LED Flood Light SMD Flood Light 50W, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ferrite Core for Power Transformer (Ee16e), 1996;Aluminium Unitized Curtain Wall for Office Building, Gymnasium and Hotel., 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 (China Manufacturer Wallpaper House Decoration Wall Paper,1991).Flexible Magnetic Rubber Sheet Soft Magnetic Tape. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Electronic Power Control Smart Pdlc Film/ Switchable Smart Glass/Smart Privacy Dimming Glass,Electric Wine Bottle Opener K020,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,Modern Etch Web Pendant Lights Stainless Steel Lampshade for Home Decor Lamp Fixtures Kitchen(Ferrite Core for Power Transformer (Ee16e), 1996). The soluble protein may have commercial use as gelatines,China Battery Factory Direct Sale OEM 36V 2.6ah Lithium Battery, peptides or amino acids production (China Factory Wholesale Custom Cheap Football Fan Scarf (M-NF19F10010), 1991;Spine Shape Landscaping Artificial Turf Grass, 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;08bsb 40sb Double Flex Chain Alloy Steel Transmission Side Bow Chain., 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.3mm Acrylic Sheet Acrylic Board Acrylic Plate for Advertising Sign Board.

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%Condoms/Sex Toys/Capsule Toy Vending 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.
