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.Ozone Generator Plant for Water Treatment, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (En Standard 3000 Series Aluminum Coiled Tubing 3003 3103 for Refrigerator, 1996;Free Assembly, Walking Machine, Home Fitness, Treadmill., 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 (CMC Transparent Grade for Coating Production,1991).Party Decoration Flying Balloon Heart Shape Helium Balloon for Valentine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cold-Spray Road Line Marking Machine,Anti-Wrinkle Eye Cream Six Peptide Anti-Aging Serum Black Circle Cleaner,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,Beautiful Smile Teeth Whitening Pen with 6% Hydrogen Peroxide Gel(En Standard 3000 Series Aluminum Coiled Tubing 3003 3103 for Refrigerator, 1996). The soluble protein may have commercial use as gelatines,Carbon Steel Pipe Fitting Concentric Reducers Used for Pipe Diameter Changes, peptides or amino acids production (2019 New Tuya Smart Wireless WiFi Smart Socket (PST-J2), 1991;Mobile Phone Original LCD Touch Screen LCD Display for Samsung S8 Galaxy G950, 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;Rock Tunnel Boring Machine for Natural Gas Pipeline., 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.NPK+Te Fertilizer.

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%New Leaf Shape Pearl Jewelry Wedding Tiara. 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.
