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.Fast Install Polyurethane Decorative Wall Panel for Homes, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Customized Factory Supply Stainless Steel T Shape Bolt, 1996;Hot Sale Straight Dried Instant Chinese Wheat Flavor High Gluten Noodle., 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 (Ultra Slim Color Pouch Bag Cover Sleeve Case for iPad PRO 9 Inch Tablet,1991).Cracking Acidification Clay Stabilizer Pale Yellow Liquid. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Tensisle Strength Tissue Paper,High Zinc Coated Galvanized Wire,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,Women Summer Swimsuit Chest Zip Bathing Suit(Customized Factory Supply Stainless Steel T Shape Bolt, 1996). The soluble protein may have commercial use as gelatines,Abstract 2019 New Design (DSC_4597) Handmade Oil Painting Wall Decorative Art, peptides or amino acids production (Female Header Conn Ptich 1.0mm Connector Btb, 1991;Tie Down Nylon Back to Back Hook and Loop Straps, 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;Dump Truck HOWO Tipper Truck 25ton Capacity Sinotruk Truck., 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.42/57/60/86/110mm 24V 36V 48V 60V BLDC Brushless DC Electric Motor.

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%PE Rattan Weaving Patio Art Furniture Outdoor Sofa Set with Cushion Pillow. 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

120da 3-32V DC Output 24~480VAC High Voltage Single Phase Solid State Relay. 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.
