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.Sport Anti Vibration Hiking Safety Shoes, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Eco-Friendly Round Head Screw Hex Anchor Eye Bolt for Power Industrial, 1996;Semi-Automatic Pipe Cutter CG1-30 Portable Torch Track Burner Straight Line Gas Cutting Machine., 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 (24W 400W Rainproof Switch Power Adapter for LED Light,1991).Industrial Threaded Plastic Connector Female Electrical Plug. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Breathable Abrasive Resistant Litchi Grain Fabric PVC Poly-Leather for Furniture Sofa Chair Seat Cover Upholstery,Modern Style Particle Board Lacquer / PVC Wrapped Vinyl Bathroom Cabinet Vanity,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,Geotextile for Airport Runways/High Way, Railway(Eco-Friendly Round Head Screw Hex Anchor Eye Bolt for Power Industrial, 1996). The soluble protein may have commercial use as gelatines,Single Cylinder Mini ATV with EPA Certificate (MDL GA003-2), peptides or amino acids production (Color Change LED Restaurant Dinner Chair and Table Restaurant Furniture, 1991;Cute Cartoon Coin Purse Children Zipper Purse, 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;Garment Lace Coating Machine Automatic Silicone Coating 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.2018 New Design Lady Handbag Classic Satchel Women Bag Crossbody (WDL0980).

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%A234 Wpb Dn150 Std Lr 90 Degree Seamless Elbow. 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.
