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.Hotel Bedding, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Supplier V Wedge Wire Johnson Water Well Screen, 1996;Clear Black Empty 15ml 30ml 50ml 100ml Frosted White Square Glass Perfume Bottles., 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 (10A MPPT Solar Controllers PV 60V for off-Grid,1991).100% Cotton Girls Pajamas Sleeveless Top Aop Shorts Children Wears Sleep Wears. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Colorful Boys Outdoor Flat Beach Sandal with PU Upper and TPR Outsole,60ml 100ml Customized Glass Jar for Spice, Candle, Candy,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,Aluminium / Stainless Channel Letter Auto Profile Bending Machine Price(Supplier V Wedge Wire Johnson Water Well Screen, 1996). The soluble protein may have commercial use as gelatines,Ctg Dry Drum Overband Magnetic Separator for Mangnese /Iron/Limonite Ore Processing Line, peptides or amino acids production (Factory Outlet Automatic Grain Tower Dryer Drying Equipment, 1991;Mesh Bag Packing 20kg Pure White Garlic, 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;Supreme 524 Mv Sea Kayak., 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.Trunk Organizer Foldable Water Proof.

The filtrate in branch B was treated in the same way as branch B inJumbo Pleated High Flow Filter 20 to 60 Inch. The final soluble protein shown were used for peptides separations using gel permeation chromatography,PAC /Poly Aluminium Chloride for Water Treatment.

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%Aluminum Sheet Shearing 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.

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.

Tomato Bubble and High Pressure Washing Machine(HPLC)

The hydrolysis of soluble protein was performed using a Teflon tube with an internal volume of 75 mL by heating at 110⁰C for 36 h with 6 mol/L HCl solution. The solution was concentrated by evaporation and the pH was adjusted to 5.0 - 5.5.Upholstery Ribbon Christmas Tape⁰C (flow rate 0.3 mL/min.). Ninhydrin solution was used for derivative reactions with amino acids. The eluents used were: mobile phase A: buffer solution of 0.2 mol/Raggae Series Black Friday E Liquid Wholesale Disposable Vape Pen E Juice E Liquid Flavor Concentrate, pH 3.25., mobile phase B: buffer solution of 0.01 mol/2+1 Flavors Soft Ice Cream Machine with Pre-Cooling, pH 7.40.
