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.Tpdl Belt Press Sludge Equipment with Slaughtering Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (3000W 3kw with 50A PWM Controller 24V Hybrid Solar Inverter (QW-3VA2450 PLUS), 1996;The Most Demanded Products Fluorescence Microscope Camera., 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 (Low Price Promotion Soda Ash Light to Papermaking,1991).Gold Glass Dropper Bottle 20ml 30ml 50ml 100ml Spray Bottle. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,HOWO 420HP Rhd Tractor Truck Head,Cummins Generator Set Diesel Engine Spare Parts Fuel Pump Support 4991549,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,Decorative Bathroom Illuminated Smart Backlit Rectangle LED Mirror with Blue Tooth(3000W 3kw with 50A PWM Controller 24V Hybrid Solar Inverter (QW-3VA2450 PLUS), 1996). The soluble protein may have commercial use as gelatines,Crankcase Breather Pipe Hose 11157542633 Fit for BMW E87 E90 E91 N46, peptides or amino acids production (China Supplier AC DC E27 Emergency Rechargeable LED Bulb LED Bulb, 1991;Gaint Inflatable Animal Slide, 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;White 4*8FT 18mm PVC Foam Board for Cabinets Use., 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.Dual Function Write Ball Pen Aluminum Stylus for iPhone Xs X Se.

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%Professional OEM Plastic Mould / Molding Service Maker Plastic Injection Mold. 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.
