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.High Zinc Coated Galvanized Wire, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Women Summer Swimsuit Chest Zip Bathing Suit, 1996;Abstract 2019 New Design (DSC_4597) Handmade Oil Painting Wall Decorative Art., 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 (Female Header Conn Ptich 1.0mm Connector Btb,1991).Tie Down Nylon Back to Back Hook and Loop Straps. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Dump Truck HOWO Tipper Truck 25ton Capacity Sinotruk Truck,42/57/60/86/110mm 24V 36V 48V 60V BLDC Brushless DC Electric Motor,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,Ilife Double Canoe Kayak Single Canoeing Kayak Fishing Kayak Big Fishing Kayaks(Women Summer Swimsuit Chest Zip Bathing Suit, 1996). The soluble protein may have commercial use as gelatines,Industrial Automatic Best Price Professional Corn Curls Kurkure Cheetos Nik Naks Corn Puff Snacks Food Extruder Machine Electric Gas Popcorn Making Machine, peptides or amino acids production (High Quality Warm Paste Packaging Machine, 1991;Stainless Steel Resin Trap Strainer, 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;Small Bar Fridge with Glass Door for Beverage and Beer., 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.Fcatory Supplu High Quality 7010b Low Price 2 DIN 7 Inch Car MP5 Player, Mirror Link and Built-in Bluetooth Car Radio Car Player.

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%Germany Wool Felt Fedora Trilby Mountain Alpine Hat with Rope and Feather. 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.
