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.Gym Fitness Equipment Adjustable Weight Bench, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Sell P7.8 Transparent LED Display Screen, 1996;Automatic Hotel Laundry Equipment Bed Sheet Folding Machine (ZD3000-V)., 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 (Original Weichai Engine Truck Spare Parts Valve Cap 61500050105,1991).Sliding Panel Saw Heavy Duty CNC Band Saw for Furniture Ban Resaw Machine for Lumber, Round Log Slinding Sawmill, Band Resaw for Lumber. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Ceramic Edge Protection Profiles Decorative Ceramic Metal Tile Trim,Charms for Jewelry Making (Sold Per Bag 10PCS Inside),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,Fused Quartz Powder 325mesh 500mesh 1250mesh(Factory Sell P7.8 Transparent LED Display Screen, 1996). The soluble protein may have commercial use as gelatines,Various Types of Plastic Hooks Mould From Manufacturers, peptides or amino acids production (New Wholesale Bamboo Plastic Pet Bottle Square Shoulder 250ml Pet Bottle Rectangle Bottle, 1991;10kv Electrical Power Transmission Galvanized Steel Tubular Mono Pole Tower, 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;Special Flower Shaped Sterling Silver Cubic Zirconia Earring for Lady Wedding Gift., 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.Waste Tire Cutter Machine Tire Shredder Equipment Price Tyre Shredder India.

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%European Good Quality Bathroom Simple Sliding Glass Shower Cabina. 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.

CONCLUSIONS

Whole Producing Line Salt Bath Bomb/Salt Tablet/ Salt Block Making Hydraulic Press Machine. Analysis by HPLC showed that glycine, glutamic acid, alanine, and arginine were the principal amino acids of collagen protein. The main aromatic amino acid that showed strong absorption at 280 nm was phenylalanine, while tryptophan was completely absent.
