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.


Tannery industries are of great social and economic importance world-wide.Automotive Perforated Metal Stamping Part for Furniture, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Auto Car Accessories Seat for Child, 1996;Heating Refrigerated Low Temperature Cooling Circulator Water Chiller., 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 (Zipper Pouch Pistachio Nuts Premade Packing Machine,1991).Original Cummins Diesel Engine Spare Parts Flywheel Ring Gear. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cheap Price Popular Personal Care Tool Battery Powered Nose Hair Trimmer,Colombia Outdoor P5 Pantallas LED Display,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,2019 Smart Watch Men Women Heart Rate Monitor Blood Bracelet Smartwatch Sport Watch(Auto Car Accessories Seat for Child, 1996). The soluble protein may have commercial use as gelatines,2010 Used Foton Truck Mixer, peptides or amino acids production (Single Board 3.7V~24VDC Microwave Detector PCB, 1991;Automatic Chicken Nipple Drinker System, 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;Industrial Hydraulic Ice Grape Press Machine., 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.Common Rail Diesel Injector Nozzle Dlla153p977.

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%Heavy Zinc Galvanized and PVC Coated Binding Cut Iron Wire Stainless Steel Wire. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
