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.Abstract Light and Shadow Metal Oil Painting for Deco, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Silo Machine Equipment for Chicken Farm Feed Use (JF-A-L003), 1996;Cheapest Container Living House/Office/Kiosk., 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 (Spin Centrifugal Demister Separator or Column Internal,1991).Baby Wet Wipe Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Closed Impeller Centrifugal Pump Mining Pit Diesel Engine Drive Pump,Shiny 100% Polyamide 280t 70d Plain Pleat Fabric Jacket Fabric,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,360 Degree Reciprocating Car Wash Machine(Silo Machine Equipment for Chicken Farm Feed Use (JF-A-L003), 1996). The soluble protein may have commercial use as gelatines,Temperature Sensor Customized Thermostat for Industrial Appliances, peptides or amino acids production (Custom Die Aluminum Castings, 1991;High Quality Meat Pie Making Machine with Different Mould Shape, 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;Gear Operated Flanged High Performance Butterfly Valve., 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.China Supplier Sinotruk HOWO 6X4 Trailer Head Tractor Truck.

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%Fashion Cotton Baby/Kid Hat (DH-BF332). 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.

CONCLUSIONS

Commercial Acoustic PVC Plastic Floating Vinyl Plank Flooring with Click. Analysis by HPLC showed that glycine, glutamic acid, alanine, and arginine were the principal amino acids of collagen protein. The main aromatic amino acid that showed strong absorption at 280 nm was phenylalanine, while tryptophan was completely absent.
