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.Living Room Furniture 2 Seat Purple Velvet Back Sofa with Metal Feet, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (300 Degree Automatic Hot Pressing Hot Press with Mould Size 200X200mm, 1996;Silent Diesel Generator Powered by Perkins Engine 125kVA (YMP-100)., 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 ((SANLI) 25m3/H Concrete Machinery Automatic Elevator Bucket Mini Concrete Mixing Station,1991).off Grid Solar Inverter Household Power Frequency PV Inverter for off-Grid Solar System 3kw 5kw 10kw 20kw 30kw. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Brown Cake Box Party Cupcake Pastry Cookies Packing Corrugated Paper Boxes,Modern LED Oblique Aluminum Tube Hotel Whollesale Pendant Lighting,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,Fiber Optic Terminal Equipment 1ge Epon ONU with WiFi(300 Degree Automatic Hot Pressing Hot Press with Mould Size 200X200mm, 1996). The soluble protein may have commercial use as gelatines,Embossed Wood Grain Decorative PVC Sheet for PS MDF PVC Metal, peptides or amino acids production (20 Experiences on Plastic Injection Moulding Service, 1991;Wind Protection Screen. Wind Dust Netting, Wind Dust Net, 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;24K Gold Rolling Paper Shine Papers Cigarette Paper., 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.Two - Way Double Row Thrust Tapered Roller Bearings.

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%Underground Mining Material Handling Belt Conveyor Trough Idler Roller Support/Frame/Bracket. 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.
