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.Anti-Abrasion PVC Artificial Leather for Car Seat (128#), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Digital Control with LED Display DC Solar Small Deep Freezer Fridge, 1996;Automatic Economical Check Weigher with High Speed., 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 (Small Lovely Girls′ Backpack Plush Backpacks with Stitching Pocket,1991).Steel Handle Rake Flat Rake Garden Rake Agricultural Rake. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Quality Small Tea Bag Packing Machine Price,Carbon Dioxide Gas with 50L Seamless Cylinder,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,UV8d Wouxun High Gain Antenna Dual Band Antenna(Digital Control with LED Display DC Solar Small Deep Freezer Fridge, 1996). The soluble protein may have commercial use as gelatines,Fiberglass Covered Insulated Flat/Square Aluminum Magnet Wire, peptides or amino acids production (Portable EMS Shock Wave Massage and Sport Pain Therapy Equipment Beauty Machine, 1991;Swbf 7b2s Bolt Former, Bolt Machine, Cold Forging Machine, Cold Heading Machine, Parts Former, Nut Tapping Machine, Threadrolling Machine, Automatic Bolt Making, 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;Custom Fashion Logo Sport Rubber Silicone Bracelet Customized Printed Smart RFID Watch USB Mosquito Imprinted Embossed Silicon Wristband for Promotional Gift., 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.Smiley Canvas School Backpack for Teenagers Girls.

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%Dongfeng 4X2 10000L Water Spinkling Tank Transport Truck. 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.
