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.Industrial High Pressure Food Quality Rubber Hydualic Hose for Water Food, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Safe Delivery Effective Sarms Mk 677 for Bodybuilding, 1996;12# X 14# Electric Galvanized Double Strands Barbed Wire., 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 (OEM Service Machining Milling Turning Service Custom CNC Aluminum Case,1991).Wholesale Mini School Backpack for Girls. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Sy03-05-006 Apple Shape Wallet Silicone Bag Coin Purse,Super Potassium Humate Shiny Flakes,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,4K Giant Whiteboard Interactive Panel for University Whiteboard(Safe Delivery Effective Sarms Mk 677 for Bodybuilding, 1996). The soluble protein may have commercial use as gelatines,Auto Hydraulic Shock Absorber 48510-09K80 for Toyota Hilux Kun25, peptides or amino acids production (Electric Massage Bed Pedicure Chair with Double Dust Collector, 1991;750ml Spirits/Vodka/Whisky/Rum/Water//Brandy/Wine Glass Bottle with Handle, 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;Adjustable Solar Mounting Kits (GD1059)., 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.Bgf-800 BOPP Dry Laminating Machine.

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%Rutile Anatase Titanium Dioxide for Coating and Paints. 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.
