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.Custom Fashion Cup Mat Silicone Rubber Coaster for Tea- Best Housewarming Beverage, Drink Silicone PVC Coaster Beer Drink Coaster Cup Coaster (YB-CC-1), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Aluminum Foil PE Bottle Cap Induction Seal Liner, 1996;Aluminium Profile/Shell/Housing for T5/T8 LED Tube Light (SQ-HRJ-002)., 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 (Sophisticated Durable Membrane Panel/Panel with 3m Glue,1991).Automatic Packing Machine for Chili Powder Spice Powder Red Pepper Powder. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,HDPE Polyethylene PE Pipe for Water Supply,Embossing Waterproof Push Button Membrane Switch Panel Membrane Keypad,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,Plug-in Supermarket Chest Type Display Freezer with Sliding Glass Door(Aluminum Foil PE Bottle Cap Induction Seal Liner, 1996). The soluble protein may have commercial use as gelatines,Hot Sell High Quality and Best Price Fitness Oval Tube Commercial Gym Equipment 8 Multi Station, peptides or amino acids production (Galvanized Pressure Locked Grating, 1991;Phenol Polyoxyethylene Ether for Water-Reducing Admixture, 9004-78-8., 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;2019 Ce Approved Car Spray Booth /Furniture Infrared Paint Spray Booth., 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.Trending Hot Products Rotary Floor Cleaner Microfiber Cleaning Mop Bucket.

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%High Frequency Pure Sine Wave 25kw Inverter 240V off-Grid Solar Power Inverter. 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

Customized Precision Hydraulic Cylinder Metal Machinery Parts for Forklift. 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.
