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.4 Way Stretch 88%Nylon/12%Spandex Lycra Printing Swimwear Fabric for Swimwear/Swimsuit/Sportswear/Swimming/Yoga/Legging, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (22kw Electric Vehicle Charger Station Charging Point with Type2 Cable 18 Feet, 1996;Yashi 98 Inch Display Multi Touch Interactive Whiteboard   LCD., 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 (Low Power Consumption Laser Foam Vertical Die Cutting Machine,1991).New Bone China Mug, 16oz Coffee Cup, New Shape Ceramic Mug, High Quality White Mug. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Agriculture Plastic Film Polycarbonate Metal Prefab Greenhouse,Q235 Jr Hollow Structual Section Steel Tubes with Good Quanlity,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,H2309 H2310 H2311 H2312 H2313 H2314 H2315 H2316 (H2317 H2318 H2319 HE211)(22kw Electric Vehicle Charger Station Charging Point with Type2 Cable 18 Feet, 1996). The soluble protein may have commercial use as gelatines,Custom Orange Color Delrin Sheet POM Board for Automobile Industry/POM Sheet/POM Rod/Acetal Rod/Delrin Sheet/Delrin Rod/Blue Delrin Sheet/Color Delrin Sheet, peptides or amino acids production (High Quality Crusher for Used Plastic Recycling Line, 1991;High Torque Low Rpm DC 24 Volt Motor Servo Brushless Motor Kw 750W 24V 750W BLDC Motor High Rotating Speed Agv Drive Unit, 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;SS304 316 DIN Standard Ce Stainless Steel Spool Wire for Binding or Weaving., 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.Wear Resitant Rope End Cap Plastic Flange Cover.

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%10L/15L/22L/32L/42L/52L Portable Camping Fridge Compressor Beverage Lcebox Cooler Box Chest Freezer Car Refrigerator Mini Fridge for Car/Home/Outdoor. 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.
