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.Robe Pointe 10r Sharpy 280W Beam Spot Wash Moving Head, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Medical Ce Approved Bp Machine Blood Pressure Monitor, 1996;Max/Min Freezer Temperature Digital Thermometer Sensor Probe Tpm-900/Tpm-910., 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 (2 Layers Large Plastic Blow Molding Machine/Blowing Moulding Machiery,1991).Customized CNC Precision Micro Machining Parts with Screw Thread Mirror Polish. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Wireless CMOS Car Backup Camera with 7 Split Quad DVR LED Monitor,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,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,Mini Electric Chain Saw Cutting Machine Price(Medical Ce Approved Bp Machine Blood Pressure Monitor, 1996). The soluble protein may have commercial use as gelatines,A2 Grade Fireproof Customized Color ACP Sheet, peptides or amino acids production (Ce Approved Cheap Medical Disposable Electrical Infusion Pump, 1991;Fashion Party Decoration Classic Wine Glass Accessories Jewelry, 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;Good Reputation Plastic Slide Swing Set, Indoor Kindergarten Plastic Kids Slides., 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.32W Dimmable Interior Ceiling LED Recessed/Flush Can/Spot Down Lights for Cloth/Retail Stores.

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%High Quality 20PCS Colorful Makeup Brush Set. 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.
