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.TUV Approved Y Splitter 2 Way Solar Mc4 Y Branch Connector, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (CNC Laser Customized Telescopic Steel Cover, 1996;High Precision Mini Laser Cutting System., 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 (Mill Finish Black Steel Grating Stock Panel Grating From Ningbo Jiulong,1991).1350ml Round Shape Borosilcate Lunch Box Office Used (GB13G17195). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,One to One Order Following Strong Real Gold Thread,New Design Paper Pyramid Memo Cube with Ribbon for Promotion,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,Plastic Medallion, Plastic Ceiling Rose(CNC Laser Customized Telescopic Steel Cover, 1996). The soluble protein may have commercial use as gelatines,PP PE PVC Single Wall Corrugated Pipe Making Machine Line, peptides or amino acids production (Lace Control Hiphugger Braless Latex Body Shaper L81187, 1991;Customized Precision Non-Standard Hardware Clamp Nylon/Steel CNC Turning/Stamping Parts, 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;Galvanized Diamond Wire Mesh/PVC Coated Chain Link Fence., 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.Good Price Servo Motor Running OPP Film Bag Sealing Big Cushion Packing 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%25X75m Big Temporary Storage Tent for Storage/ Warehouse Solution 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.
