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.Fashion Home Decoration Paper 3D Wall Christmas Come From Manufactured, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cow Dung Chicken Manure Organic Fertilizer Making Machine, 1996;marble Makeup Brush Set for Travel in 20PCS., 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 (Swimming Pool Water Disinfect Ozone Generator,1991).20kv 50kVA High Voltage Dry Type Power Supply Transformer. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Manufacturer Custom Injection Molded Plastic Shell of Automobile Headlamp,High Quality OS2 12 Core Singlemode High Density Data Center MPO-LC Breakout 2mm Low Insertion Loss 5m LSZH Fiber Optic Patch Cable Per Meter,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,4 Styles Blue Glass Crystal Butt Beads Spiral Plug(Cow Dung Chicken Manure Organic Fertilizer Making Machine, 1996). The soluble protein may have commercial use as gelatines,Electronic Automatic DC Motor Valve Industrial SUS Welded Ball Valve, peptides or amino acids production (Industrial Activated Carbon Water Filter Industry Water Treatment, 1991;2016 New Generation Sausage Making Machine, 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;Magnetic Mixer Mixing Tank with Bottom Agitator (MTK)., 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 Aluminum Frame Outdoor Advertising Pop up 3X3 Custom Portable Folding Gazebo Tent.

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%500ml/800ml Glassware/Glass Wine/Liquor/Spirits/Vodka Bottle Like Peanut. 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.
