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.Sanjing PVC Lining Layflat Fire Hose, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Qt10-15 Automatic Concrete Cement Hollow Solid Paver Curbstone Brick Block Making Machine Price in Madagascar, 1996;China High Quality and Cheapest Price 15W 18W 20W 6′′ LED Down Light., 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 (Automatic CNC Glass Cutting Machine Glass Cutting Table,1991).Dual Working Solar Motion Wall LED Lamp Light From ISO9001 Factory. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Automatic Moder Double Seal Nipple Drinking System for Broiler Chicken,Paraffin Wax Fully and Semi Refined 56 58 60 62 From Factory Bottom Price,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,Pet PP Rope and Broom Wire Drawing Machine(Qt10-15 Automatic Concrete Cement Hollow Solid Paver Curbstone Brick Block Making Machine Price in Madagascar, 1996). The soluble protein may have commercial use as gelatines,14 Oz Paper Food Packaging Noodle Sushi Salad Bowl Cup, peptides or amino acids production (PTFE Seat Wafer Butterfly Valve Pn16, 1991;Waterjet Intensifier High Pressure Cylinder Waterjet Cutting Machine Spare Part, 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;China Supplier Single Person Fishing Boat Angler Pedal Kayak 10FT for Adults., 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.Restaurant Elevator Lift for Kitchen Residential Hotel Dumbwaiter in China.

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%Metal Steel Frame Membrane Structure Car Parking Shed Cover Design. 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.
