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.Lab Equipment 3 Part Blood Cell Counter Auto Hematology Analyzer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ball Mill, Grinding Mill, Mining Equipment, 1996;Used Tyre Recycling Plant for Reclaimed Rubber Production., 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 (Fan Speed Controller RF Transmitter and Receiver Control Switch Kl-K201c,1991).Robe Pointe 10r Sharpy 280W Beam Spot Wash Moving Head. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Medical Ce Approved Bp Machine Blood Pressure Monitor,Max/Min Freezer Temperature Digital Thermometer Sensor Probe Tpm-900/Tpm-910,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,2 Layers Large Plastic Blow Molding Machine/Blowing Moulding Machiery(Ball Mill, Grinding Mill, Mining Equipment, 1996). The soluble protein may have commercial use as gelatines,Customized CNC Precision Micro Machining Parts with Screw Thread Mirror Polish, peptides or amino acids production (Wireless CMOS Car Backup Camera with 7 Split Quad DVR LED Monitor, 1991;Jieshuai 3 in 1 USB Cable, Fast Charging Data Cable, Universal Micro USB Cable, Lightning Cable, Type C Cable, Suitable Apple iPhone and Android Charge, 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;Mini Electric Chain Saw Cutting Machine Price., 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.A2 Grade Fireproof Customized Color ACP Sheet.

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%Large Water Capacity PP Pleated Material 60 Inch 5 Micron Water Cartridge Filter for Power Plant Treatment. 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.

CONCLUSIONS

304/304L 2b Stainless Steel Sheet and Steel Plate. Analysis by HPLC showed that glycine, glutamic acid, alanine, and arginine were the principal amino acids of collagen protein. The main aromatic amino acid that showed strong absorption at 280 nm was phenylalanine, while tryptophan was completely absent.
