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.LED UV Curing Machine for UV Cured Floor Coatings TM-LED600-6, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Custom 30ml Green Dropper Glass Bottle Cosmetic Essential Oil Bottle, 1996;Durable TPR Pet Molar Toy with Colorful Rope., 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 (Manufacturer Wholesale Adjustable 2mm 5mm Strong Downlight High Torque Brake Pedal Clutch Clothespin Hook Torsion Spring Clip Light Duty Using Flat Wire Spring,1991).Chromium Oxide Green 99% for Construction and Plastics. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Zs Round Vibrating Sieve,Stainless Steel Tactile Paving Blind Road Stud,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,70L Lab Use Refrigerated Circulator Chiller Factory Price(Custom 30ml Green Dropper Glass Bottle Cosmetic Essential Oil Bottle, 1996). The soluble protein may have commercial use as gelatines,Packaging Machine Automatic Weighing Filling Machine (AH-FJJ 100/300/500), peptides or amino acids production (Roller Hearth Heating Furnace for Gas Cylindrer, 1991;custom design MIFARE DESFire EV2 2K plastic RFID loyalty card, 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;Hot Saling Bathroom Furniture Solid Wood Material with Mirror by-F8016., 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.Hotel Card Door Lock Access Control Safe Door Lock.

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%FPC Hotbar Soldering with Exposed Lead Flex for PCB Soldering. 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.
