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.Water Chiller Air Cooled for Cooling Beer Refrigerating, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Cheap Price Disposable IV Infusion Set with Precise Filter, 1996;Q3210 Vibratory Polishing Shot Blasting Machine., 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 (Gym Workout Anti-Cellulite Compression Push up Trousers Fitness Leggings Sports Wear,1991).Big Dimension UHP Graphite Electrodes for Steel Making. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New Design Pet Product, Climbing Willow Cat Scratcher Tree,Full Automatic 100X120mm Hexagonal Gabion Woven Wire Mesh Knitting Machine,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,Nordberg C110 C125 C140 Jaw Crusher Spare Parts Fixed / Swing Jaw Plate(High Quality Cheap Price Disposable IV Infusion Set with Precise Filter, 1996). The soluble protein may have commercial use as gelatines,Commercial Inflatable Dry Slide for Kids, Animal Theme Kids Toys Fun City Slide, Factory Price Inflatable Bouncing Slide, peptides or amino acids production (Single and Multi Rope Wire Mine Hoist From China, 1991;New Technology Semi-Auto Pet Plastic Bottle Blow Molding Equipment Plant Machine, 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;Metal Hand Folding Machine 1.5mm Aluminum Sheet Manual Bending Machinery., 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.High Quality Electronic Circuit Board Supplier PCB Assembly.

China Shipping Logistics to Stockholm(2.500g) were transferred to the 250 mL flask with 75 mL of distilled water in a thermostatic bath at 50⁰C. After 2 h, the solid was filtered using qualitative filter paper (200m Diesel Oil Hydraulic Water Well Drilling Machine).CNC Lathe Main Parts with Good Quality(branch B) until pH 10, in order to precipitate Cr(OH)₃. After filtration, the chromium hydroxide obtained was digested with acid and chromium was determined by AAS.

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%1.0mm Binding Wire Galvanized Iron Wire. 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.
