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.UV Resistant Single Component Water Based Polyurethane Waterproof Coating, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Steel Rubber Seal for Dust Proof, 1996;Industrial Steel Structure Mezzanine Rack Platform System/Book Shelf., 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 (Kindergarten Playground Preschool Kids Plastic Slide and Swing,1991).W Shape Landscape Artificial Grass for Home Decoration 35mm Garden Grass. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,COB LED Integrated All in One Solar Street Light with LiFePO4 Lithium Battery,High Quality Injection Plastic Water Cup Mould Manufacturer Taizhou,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,New Virgin Teflon PTFE Teflon Gaskets/Back up Rings(Steel Rubber Seal for Dust Proof, 1996). The soluble protein may have commercial use as gelatines,Capacitive Push Button Membrane Keyboards, peptides or amino acids production (Copper Nickel 90 / 10 Pipe Fittings 180 Degree Lr Elbow, 1991;High Quality 12 Colors Moisturizing Glitter Shiny Lip Gloss, 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;Europe Style Wholesale Custom PVC Double Bathroom Cabinet Vanity Mirror Cabinet., 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.Dtp18650-2s2p 14.8V 2200mAh 2600mAh Customizable Li-ion 18650 Battery Pack.

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%99% Purity Caustic Soda Flakes From Direct Manufacture on Sale. 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.
