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.Biodegradable Kraft Paper Soup Cup Instant Noodles Bowls with Lids, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (New Cisco Aironet 3700 Series Wireless Access Point Air-Cap3702e-B-K9, 1996;Portable Telescopic Straw Metal Drinking Straw with Brush Case., 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 (Frameless Sliding Shower Enclosure in Bathroom with 8mm Clear Glass and Stainless Steel Hardware,1991).Etching Rear Trunk Sill Plates for Hyundai Tucson. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Quality Horizontal Flat Bed Metal CNC Turning Lathe Machine Price Ck6163,Lab Equipment Sr Paper Pulp Beating Freeness Test 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,CREE COB Meanwell Driver Walkway Lamp 45W LED Canopy(New Cisco Aironet 3700 Series Wireless Access Point Air-Cap3702e-B-K9, 1996). The soluble protein may have commercial use as gelatines,Car Spare Parts Eco-Friendly Stitch Car Foot Mats for Newest Nissan Altima, peptides or amino acids production (Popular Water Bike / Hydro Bike / Aqua Bike (SK-8001), 1991;Fertilizer Granulator Machine, Compound Fertilizer & Organic Fertilizer Granulator, Machine for Making, 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 Roller Rotary Wood Peeling Machine with CE for Sale., 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.5in1 USB Type C Hub HDMI 4K USB C Hub to Ethernet RJ45 LAN Adapter.
