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.Auto Hydraulic Shock Absorber 48510-09K80 for Toyota Hilux Kun25, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Electric Massage Bed Pedicure Chair with Double Dust Collector, 1996;750ml Spirits/Vodka/Whisky/Rum/Water//Brandy/Wine Glass Bottle with Handle., 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 (Adjustable Solar Mounting Kits (GD1059),1991).Bgf-800 BOPP Dry Laminating Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Test-630 Automatic Protective Relay Tester,Disposable Plastic Press and Shake Fruit Juice Powder Dispensing Boost up Bottle Cap for Mineral Spring Water Bottle,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,Tpdl Belt Press Sludge Equipment with Slaughtering Machine(Electric Massage Bed Pedicure Chair with Double Dust Collector, 1996). The soluble protein may have commercial use as gelatines,3000W 3kw with 50A PWM Controller 24V Hybrid Solar Inverter (QW-3VA2450 PLUS), peptides or amino acids production (The Most Demanded Products Fluorescence Microscope Camera, 1991;Low Price Promotion Soda Ash Light to Papermaking, 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;Gold Glass Dropper Bottle 20ml 30ml 50ml 100ml Spray Bottle., 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.HOWO 420HP Rhd Tractor Truck Head.

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%125mm Wet Diamond Pad for Polishing Marble. 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

2018 New Design Lady Handbag Classic Satchel Women Bag Crossbody (WDL0980). 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.
