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.Home Depot Electric Fireplace with Deco Insert Gas Heaters Fan Modern Furniture, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wood Handle Carbon Steel Sickle S202, 1996;High Quality Custom Golden Colored Powder Pill Organizer., 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 (Cooperate with Brand Companies High Intensity Safety Reflective Red Jacket,1991).Disposable Pipette Tip 40~200UL with Ce. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Amusement Park Kids Ride on Train Electric Kids Track My Train (14 seats) for Sale,1.5 Oz Mini Hexagon Glass Jars with White Plastisol Lined Lids,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,86 Type WiFi Smart Touch Switch Controll by Tuya APP(Wood Handle Carbon Steel Sickle S202, 1996). The soluble protein may have commercial use as gelatines,100% Wool Felt Wide Brim Fedora Trilby Hat, peptides or amino acids production (Super Handy Home & Office & Hotel Facial Tissue Paper, 1991;Pointed Compound Pliers Reduction Forceps Bone Reduction Forcep, 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;Hidden Handle Safe for Children in Bathroom Cabinet., 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.Livestock Poultry Farm Pig/Sow/Hog/Piglets Breeding Machine for Sale.

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%Blince Omsy/Oms Series Hydraulic Orbital Motor Replace Danfoss Oms Motor. 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.
