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.Professtional Suppliers Yutong Golden Dragon Bus Spare Parts, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Shaffer Hydril Double Single RAM Bop for Wellhead with API 16A Certificate, 1996;Glossy and Matte Finish Solid Surface Bathroom Wash Basin Wash Sink., 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 (220V/50Hz Stainless Steel Ozone Generator with 5g/H,1991).Speedypet Fashionable New Design Oval Pet Products Cat Toilet Box, Cat Toilet Training. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Self Adhesive Paper Stickers 13.56MHz NFC Anti-Theft Security RFID Label Tags for Alcoholic,Luxury Jewelry White Gold Plated Engagement Diamond Ring,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,Free Sample Cheap Price Plastic Black Underwear Hanger for Sale(Shaffer Hydril Double Single RAM Bop for Wellhead with API 16A Certificate, 1996). The soluble protein may have commercial use as gelatines,13.56MHz Nfc Ntag213 Ntag216 RFID Dry Inlay, peptides or amino acids production (100% Cotton Face Mask in Guangzhou, 1991;OEM High Pressure Machined Part Die Aluminum Casting, 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;AISI 430 Ba/2b Embossed Stainless Steel Sheet., 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.High Quality 33kv 6.3kv 1000 kVA 50% Copper and 50% Aluminum Material Distribution Transformer Made in China.
