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.High Quality 12 Colors Moisturizing Glitter Shiny Lip Gloss, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Europe Style Wholesale Custom PVC Double Bathroom Cabinet Vanity Mirror Cabinet, 1996;Dtp18650-2s2p 14.8V 2200mAh 2600mAh Customizable Li-ion 18650 Battery Pack., 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 (Manufacturer Custom DSLR SLR Camera Sling Backpack with Zipper,1991).12V 96LED Outdoor Lighting Solar Torch Light for Christmas. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Second Hand/Used Hot Rolling Mill/Equipment/Machine/Production Line,SMF/VRLA Lead Acid Battery AGM Storage Battery for UPS System VRLA 12V200ah Export to UAE, India, Bangladesh, Afghanistan, Pakistan, Africa,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,High Efficiency Swimming Pool Air Source Water Heat Pump(Europe Style Wholesale Custom PVC Double Bathroom Cabinet Vanity Mirror Cabinet, 1996). The soluble protein may have commercial use as gelatines,CNC Manufacturer High Precision Custom CNC Machining Parts/ CNC Service, peptides or amino acids production (Eco-Friendly Vegetable Oil Cast Iron Multi Frying Pan, 1991;Luxury Chocolate Color Metal Tin Storage Can Candy Packaging Box, 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;QJ-M Moving small manual brick making machine with low cost., 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.Wholesale Professional High Quality Cheap Women Girls Camisole Sports Top Yoga Bra.

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%SMT YAMAHA Yv100II Yv100X Kv7-M4550-111 Kv7-M4550-112 Connection Board Assy in Stock. 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

2mm Mirror Glass/Coated Glass for LED, LCD, Computer Screen etc. 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.
