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.B45 2-Stroke Petrol Grass Cutting Brush Cutter Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Nylon Back to Back Continuous Hook and Loop Wrap Tape Strap, 1996;Chemical Plant Transfer Industrial Water Pump., 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 (Insecticidal Lamp with Solar Energy Frequent Vibration,1991).Man Technology F2000 Tipper Truck 6X4 20 Ton Dumper Truck 15269249286. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Dry Nonwoven Sakura Facial Sheet Mask for Cosmetics,Galvanized Square Washer with Timber Constructions, DIN436DIN436,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,Do Not Enter Tape Warning Tape Caution Tape Danger Tape(Nylon Back to Back Continuous Hook and Loop Wrap Tape Strap, 1996). The soluble protein may have commercial use as gelatines,CE/PED Approved Small Laminated Glass Autoclave (Diameter 1600mm), peptides or amino acids production (Anti-Corrosion Galvanized Collated Drywall Screw Dry Wall Screws, 1991;Iron Sheet Metal CNC Press Brake, Copper Aluminum Steel Plate CNC Hydraulic Press Brake for Sale Craigslist, 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;Good Quality PVC Plastic Ceiling for Wall Panel., 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.Heavy Steel Structures for Power, Cement, Coal Plant.

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%Tonva New Design Harpic Bottle Making Extrusion Blow/Blowing Molding Machine. 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.
