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.NPK+Te Fertilizer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (C Purlin/C Steel Beam/ C Section Steel/ C Shaped Steel, 1996;Customized Double Acting Hydraulic Cylinder for Excavator., 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 (Fashion High Quality Head Layer Genuine Leather Men′s Wallet,1991).Teal Blue Padded Bubble Mailer Envelopes. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Medical Ultrasound Gel,Garden Outdoor IP65 Waterproof SMD 100W 80W Motion Sensor All in One 90PCS LED Solar Street Light,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,Wholesale Blank Promotional Baseball Cap for Custom Logo Design(C Purlin/C Steel Beam/ C Section Steel/ C Shaped Steel, 1996). The soluble protein may have commercial use as gelatines,Gear Rack and Pinion for Construction Hoist, Construction Spare Parts, peptides or amino acids production (Power Plant Seawater Level Measurement Integrated Pressure Transducer, 1991;High Quality Melamine Paper Manufacturer for Decoration, 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;2019 Earn Money Cabinet Games Coin Operated Tekken 7 Retro Japanese., 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.Sfj-250r Vibrating Automatic Powder Sieve Machine with Cycling and Recovery System Replace Gema.

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%Q3210 Vibratory Polishing Shot Blasting Machine. 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.
