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.Cjx2-F (LC1-F) AC Magnetic Contactor, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (30W Portable Vehicle Bomb Moving Signal Jammer for GSM/2g/3G/4G Cellular GPS WiFi Signal, 1996;Handmade Stainless Steel Irregular Kitchen Sink Bowl (DF5545XH)., 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 (Fj22082mabts 225mm 220V AC Power Amplifier Cooling Fan,1991).Aluminum/Aluminium Extrusion Profile Housing for LED Light. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Flexible Stand up USB Charging Stands Cable Phone Charger Holder for Apple iPhone Samsung Huawei Android Phone Holders P0.11,Single Mode Sc/APC Simplex Fiber Optic Adapter,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,120da 3-32V DC Output 24~480VAC High Voltage Single Phase Solid State Relay(30W Portable Vehicle Bomb Moving Signal Jammer for GSM/2g/3G/4G Cellular GPS WiFi Signal, 1996). The soluble protein may have commercial use as gelatines,Double Lines Eco Friendly Automatic Change Rolls HDPE LDPE PLA Corn Starch Trash Garbage Coreless Rolling Smalll Volume Plastic Bag Making Machine, peptides or amino acids production (Abrasive 6 Sanding Disc for Automotive Industry, 1991;Hot Sell Advertising Industry Electronics Medicine 30W CO2 Glass Tube Laser Marking Machine, 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;2018 Hottest Sale FRP Square Mesh 38X38, 40X40, 50X50, 30X30, etc GRP Grating., 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.Piggery Accessory/Farm Pig/Sow/Piglet Accessories for Poultry Farm.

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%Plastic Anti-Static PMMA Transparent Coated Lenses Sheet Making Machine Extruder. 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.
