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.Plastic Injection for OEM Product, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cable Railng Spiral Staircase with PVC Handrail for Interior Space Saving, 1996;Durable Anti Slip Tennis Court Sport Rubber Flooring/Outdoor Court Material., 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 (Bison (China) BS2500u (E) 2kw 2kVA Ce Certificated AC Single Phase Factory Price Continent Name Generator,1991).Experienced Construction Steel Structure Building Design. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Heavy Duty 16000L High Pressure Sewer Cleaning Truck,Winter Design Acrylic Beanie /Bobble Jacquard Hat with Flowers /Machine for Knitted Winter Cap with Embroidery Circular Hat Knitting Machine,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,Non Woven Geotextile Geobag Sadbag Used for Reservoir Lake Dam(Cable Railng Spiral Staircase with PVC Handrail for Interior Space Saving, 1996). The soluble protein may have commercial use as gelatines,Portable Ink Date Printing Machine for Plastic Bag, peptides or amino acids production (High Quality Professional HD IPS 10.1 LCD Monitor with SDI, 4K HDMI2.0, 1991;High Frequency 500W Pure Sine Wave Inverter Circuit Board for Power Inverter 50Hz/60Hz, 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;Air 2 Bluetooth 5.0 Wireless Earbuds Noise Canceling Sports Earphonesfor iPhone/Android Apple Airpods., 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.Best Items Gh/Genatropin with Naked Vial.
