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.Marine Equipment Ship Ventilation Mushroom Ventilator Used in Ship Deck, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Foldable PP Plastic Storage Logistics Turnover Box, 1996;China Deep Drawing Aluminum/Aluminium Disc/Circle Cookware/Utensile/Lighting Usage with Good Flatness 1050/1060/1070/1100/3003/3005., 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 (Buddhist Mood Picture Wallpaper Murals,1991).High Quality Flange Dismantling Joint. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Duplex Stainless Steel Floating Ball Valve,E-Field Technology Credit Card and Passport Protector Card Blocker RFID Blocking Card,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,Beauty Salon Equipment Anti Wrinkle Removal CO2 Laser Machine(Foldable PP Plastic Storage Logistics Turnover Box, 1996). The soluble protein may have commercial use as gelatines,Fast Delivery Malleable Iron Pipe Fitting Hexagon Nipple, peptides or amino acids production (Gaogong Group Permanent Suspended Overband Magnetic Separator for Conveyor Belt, 1991;CNC Machine Aluminum Telescopic Covers Flat Bellows Cover, 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;7inch Desktop 1080P Media Player MP5 Car Monitor with AV Input., 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.Wholesale Price Decorative Wrought Iron Stairs Aluminium Metal Garden Fence.

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%Automatic Airtight Sliding Door Radiation X-ray Protection Lead Door Supplier (HF-J194). 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.
