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.Central Tube GYXTW 4 Core Singlemode Fiber Optic Cable, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Sell Electro Hydraulic Synchronous CNC Press Brake Kcn-30032, 1996;AISI 304 / 316 Stainless Steel Braided PTFE Hose Pipe., 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 (40mm (1-5/8′′) Carbide Oscillating Finger Grisp Rasp Tool Blade,1991).UV Protected Fireproof Fresh PE Plastic Artificial Fake Green Wall Plant Panel Bushes Leaf Foliage Flower Privacy Vertical Garden Hedge Grass Fence Screen. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Forged Steel Pressure Sealed Bonnet Globe Valve,Stable Adjustable Monitor Mounts Folding LCD Monitor Stand,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,CL2T-CBL06 Comlom Stainless Steel Pocket Multi Tool Pliers for Camping(Hot Sell Electro Hydraulic Synchronous CNC Press Brake Kcn-30032, 1996). The soluble protein may have commercial use as gelatines,Eco-Friendly Food Grade Reusable Silicone Straight Straw for Drinking with Brush, peptides or amino acids production (Manual Double Bridge Glass Cutting Table Machine (JFQG-2620), 1991;2018 New Design Red-CNC-006 CNC Machining Aluminum Precision, 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;China Factory Price Hg1 Self Adjustable Pipe Tank Rotator., 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 Crawler Excavator Track Bolt 3p2274.

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%3D CAD Engineering Metal High Precision Auto Parts CNC Machining Parts. 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.
