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.Economic and Reliable P32 Hydraulic Hose Crimping Machine Italy with SGS Certificate, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Size 000 Clear Pullulan Vegetarian Capsules, 1996;Sinicline 2018 Hot Sell Custom Printing Thank You Cards., 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 (Black Red Open Net Spandex Nylon Sexy Lingerie,1991).7W Aluminum Waterproof LED Lawn Light Use for Garden Lighting. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Jforall Liquid Water Oil Tank Pipe High Accuracy Side Top Mount Level Monitor Switch Capacitive Sensor,LED Emergency Exit Lights,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,Dn40 ISO Awwa ASME Remote Control Pneumatic Cast Iron Steel SS304 SS316 Center Line Wafer Butterfly Valve(Size 000 Clear Pullulan Vegetarian Capsules, 1996). The soluble protein may have commercial use as gelatines,25ton LPG Tank Trailer LPG Semi Trailer LPG Gas Tank for Zimbabwe, peptides or amino acids production (Column Type Pave Rubber Tile Making Machine-Vulcanizing Press Machine, 1991;Hot Sales in Amazon Store 18V Cordless Drill Vertical Battery Pack for Home Work DIY, 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;3 12 Strand 3mm 4mm 5mm 10mm 18mm Braided Dan Line Plastic PP Packing Hollow Polypropylene Rope., 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.Self Adhesive Paper Stickers 13.56MHz NFC Anti-Theft Security RFID Label Tags for Alcoholic.

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%Fully Automatic Dust Face Mask Making Machine with Ultrasonic. 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.
