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.FRP Pultruded Pipe or GRP Profile, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (6090 CO2 Sealed Glass Cooling Laser Cutting Machine, 1996;Aluminum Alloy Die Casting Parts LED Lamp Housing Radiator., 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 (Sexy Women Dress Invisible Zipper Jump Suits Fashion Hidden Zipper,1991).Outdoor Fitness Equipment Swing (JMH-03). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Sheet Metal Distribution Cabinet with High Quality,OEM Branded Low Price Disposable Baby Pull up Diapers in Bulk,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,New Type Automatic Multihead Weigher All-in-One Packing Machine for Rice(6090 CO2 Sealed Glass Cooling Laser Cutting Machine, 1996). The soluble protein may have commercial use as gelatines,Ningbo Smart Professional Manufacturer Rx Brass Pneumatic Pipe Fitting, peptides or amino acids production (Metal Animal Longhorn Skull Pendant Longhorn Skull Charm, 1991;Wholesale Bdu Uniform T/C Custom Combat Military Camouflage Tactical Army Uniform Jacket+Pant, 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;Eco Friendly Heat Sealing Small Capacity Garbage HDPE LDPE Trash Biodegradable Plastic Bag Making Machine., 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 Output Plastic Rubber Filing Masterbatch Extruder Machine.

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%Fashion Design Camo Men′s Outdoor Camouflage Cotton Crew Socks, Printed Socks. 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.
