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.Grocery Plastic Bag Corn Starch Bag HDPE Bag Automatic Sealing Vegetable Bag Flat Bag Fruit Bag Biodegradable Plastic Bag Cheap Rolling Bag Making Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Equal and Unequal High Quality Hot Rolled Steel Angle, 1996;Halal Chicken Slaughter Machine for Sale., 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 (Factory Hot Sale Low Price Big Wave ASA Roof Sheet Teja PVC for Workshop,1991).2019 Opt Shr IPL E-Light Beauty Hair Removal Machine IPL Shr. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Sarm Steroids Ostarine / Mk-2866 / Mk2866 Powder for Bodybuilding CAS 841205-47-8,3 PCS Headband for Baby Girls with Hair Bows,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,LED Flasher Relay 7 Pin for Suzuki Drz400s/Sm Gsxr Gsx Signal Light Blinker(Equal and Unequal High Quality Hot Rolled Steel Angle, 1996). The soluble protein may have commercial use as gelatines,High Quality Xanthan Gum for Personal Care and Cosmetic Applications, peptides or amino acids production (Manual Vertical Car Key Cutting Machine for Locksmith, 1991;Hot Selling Custom Logo Printed Amazon No Bubble OPP Adhesive Packing Tape, 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;Zinc Alloy Lid Zamak Alloy Casting Cap (STK-14-Z0069)., 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.Transparent Color Stretch Wrap Film Manual Operate Wrap Film.

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%Reflective Hand Hold Thermoplastic Road Marking. 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.
