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.High Speed Roll Plastic T-Shirt Bag Making Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Coffee Cup Paper Cup Plastic Cup Lid Cover Tray Plate Container Clamshell Package Thermoforming Forming Making Machine, 1996;Wholesale Black Galvanized Head Stainless Steel Screw., 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 (PE PP Ld HD Lld PP Film Recycling Units Dryer Dewatering System Plastic Compacting Machine,1991).45*60cm Anti-Fatigue ESD Rubber Floor Mat. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Carbon Steel Manifold Aluminum Tee Pipe Welding Transition Joints,Vinyl Glove in Work & Labor Glove,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,Low Energy Needed Compact Flour Mill Plant for Milling Wheat(Coffee Cup Paper Cup Plastic Cup Lid Cover Tray Plate Container Clamshell Package Thermoforming Forming Making Machine, 1996). The soluble protein may have commercial use as gelatines,Nylon Weatherproof PA6 Strain Relief Cable Gland, peptides or amino acids production (Steel Roller Embossed Paper 2019 New Design, 1991;Hot Saled Building Material 304 Cold Rolled Stainless Steel Coil, 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;Factory Price DIN5685 Galvanized Marine Anchor Link Chain., 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.Hot Salecustom Silicone Finger Rings Promotional Gift (SLF-SR001).

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%Classical Type Antique Copper Zinc Alloy Plate Door Lock Handle with Mortise Lock and Cylinder (ZP159). 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm.
