Optimization of the growth and α-amylase production of Bacillus subtilis IP 5832 in shake flask and laboratory fermenter batch cultures / Optimizacija rasta i produkcije α-amilaze Bacillus subtilis IP 5832 u šaržnim kulturama u erlenmajeru i laboratorijskom fermentoru
(Serbian Chemical Soc, Belgrade, 2011)
Cell growth and the level of α-amylase in response to the carbon and nitrogen sources used for the growth of the strain Bacillus subtilis IP 5832 were examined. Based on the amylase productivity level in shake flask cultures ...
Microwave synthesis and characterization of Pt and Pt-Rh-Sn electrocatalysts for ethanol oxidation / Mikrotalasna sinteza i karakterizacija Pt i Pt-Rh-Sn katalizatora za oksidaciju etanola
(Serbian Chemical Society, 2011)
Carbon-supported Pt and Pt-Rh-Sn catalysts were synthesized by the microwave-polyol method in ethylene glycol solution and were investigated in the ethanol electro-oxidation reaction. The catalysts were characterized in ...
The use of anodic linear sweep voltammetery analysis (ALSV) for characterization the copper anodes used for sulphur acidic waste solution treatment
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2011)
