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.Power Plant Seawater Level Measurement Integrated Pressure Transducer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Melamine Paper Manufacturer for Decoration, 1996;2019 Earn Money Cabinet Games Coin Operated Tekken 7 Retro Japanese., 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 (Sfj-250r Vibrating Automatic Powder Sieve Machine with Cycling and Recovery System Replace Gema,1991).Tungsten Solid Carbide Straight 4/6 Flutes Reamer. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,China Quality Heavy Duty Globe Control Valve,Customized Wire Harness for Various Application,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,Cheap CNC Spindle Peeling Lathe for Steel Bar(High Quality Melamine Paper Manufacturer for Decoration, 1996). The soluble protein may have commercial use as gelatines,Nonwoven Glassfibre Laid Scrim for Automotives - Reinforcements for Sound Absorption Elements, peptides or amino acids production (3 Years Warranty 3.2V 60ah 75ah 86ah 100ah 110ah 200ah Single LiFePO4 Battery Cell LiFePO4 Lithium Iron Phosphate Battery Cell for EV, E-Cars with Grade a, 1991;6063 Series Aluminium Extrusion Pipe in Hot Sell Made in China, 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;Sc LC FC St Fiber Optical Adaptor Coupler Adapter., 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.Ent Treatment Medical Chair with Foot Control.

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%Metal Hand Folding Machine 1.5mm Aluminum Sheet Manual Bending Machinery. 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.
