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.100kw Cummins Diesel Generator Set, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Double Wall Glass Vacuum Flask Bottle Stainless Steel Cola Shaped Glass Water Bottle, 1996;Luxury Hotel Furniture Antique Design Marble Side Table., 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 (Ampoule Sealer Machine Hydrogen Oxygen Gas Generator,1991).Commercial Double Lane Inflatable Carnival Bungee Run Game. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Popular Leather Cushion Home Furniture Hotel Terrace Restranant Dining Chair,Indoor Prize Selling Video Toy Story/Arcade Claw/Arcade Game/Coin Pusher /Arcade/Crane/Game /Vending Game/Claw Crane/Crane Claw Machine for Sale,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,800mm Length 600n Load Tension Gas Spring with Metal Eyelet(Double Wall Glass Vacuum Flask Bottle Stainless Steel Cola Shaped Glass Water Bottle, 1996). The soluble protein may have commercial use as gelatines,Deep Drawing Aluminum Circle /Disc for Cookwares 1050 1060 1100 3003, peptides or amino acids production (5% Humidity Range Temperature Humdity Cycling Environmental Control Chambers, 1991;Safety Full Automatic Electric Opening AAC Autoclave for AAC Plant, 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;SAE 1020 1045 4140 A36 12L14 ASTM 1215 H9 Tolerance Cold Drawn Steel., 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 Efficiency Stone Crusher Hammer Crusher Glass Crusher for Sale.

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%Motorcycle Engine Parts Motorcycle Spark Plug for CB125/Xr150L. 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.
