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.Industrial High  Temperature  Resistant Smooth Flat Wire Power Cable, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (New Fashion TPU Mobile Cover Case for Huawei, Leather Phone Case for Huawei Mate 20, 1996;Customized HSS M100*3.0 Large Thread Cutting Tools Cutter Used for CNC Milling Machine., 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 (Extruded Polystyrene Foam Board Custom Edges S/L,1991).Hite 200tc Capsule Hotel Motel Bedding Plain Bed Sheet Sets. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Magnetic Wireless Headset Metal Sports Bluetooth Headphone in-Ear Earphone Tws Wireless Earbuds Mini Bluetooth Stereo Headphone Mobile Earphone,8/16 Stands Polyethylene Hollow Braided Rope,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,Hahal Duck Slaugter Processing Equipment for Poultry Farm Abattoir Machinery(New Fashion TPU Mobile Cover Case for Huawei, Leather Phone Case for Huawei Mate 20, 1996). The soluble protein may have commercial use as gelatines,NBR EPDM Neoprene Silicone Rubber Sheet for Seal, peptides or amino acids production (Commercial Coca Cola Refrigerator with Glass Door, 1991;Flyscreen Anti-Mosquito Mesh18*16/Inch Government Company, 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;Double Jacketed Cooking Kettle Electric Jacket Boiler., 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.Fashion Gray Leggings Stretch Fitness Work out Pants for Women.

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%Eco-Friendly Vegetable Oil Cast Iron Multi Frying Pan. 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.
