more. Hydrolysis is a process that breaks down chains of polymers into monomers. In this experiment‚ we Benedict’s reagent was used both before and after hydrolysis‚ to identify reducing sugars‚ which includes both monosaccharaides and disaccharides. Benedict’s reagent changes color in the presence of reducing sugars as well as heat. Low concentrations of sugar yield a yellow to orange color while higher concentrations will be red to brown. Lugol’s solution was used before and after hydrolysis to

phosphatase were investigated using crude extracts of rat kidney. Activation of alkaline phosphatase by the metal ions was accompanied by changes in the kinetic parameters of pnitrophenylphosphate hydrolysis. The results suggest some synergistic interactions between Mg2+ and Zn2+ ions in promoting the hydrolysis of p-nitrophenylphosphate by alkaline phosphatase. The results show that assays of alkaline phosphatase activity in homogenised tissue samples will give better responses if both Mg2+ and Zn2+

should also withstand higher temperatures and lower pH and with minimal by product formation [161]. Fermentation is the key component where advancement in technology plays key role and is required to be feasible. The technologies like Separate hydrolysis and fermentation (SHF)‚ Simultaneous saccharification and fermentation (SSF) and Consolidated bio processing(CBP) are developing. CBP is in the early stages of its development and hence gaining more

Acid hydrolysis of Nb/Ta samples separates Indium from major matrix elements like Nb and Ta and the remaining elements do not influence the selective extraction and preconcentration of In and its subsequent determination by ICP-AES or flame AAS. The silica rich geological samples are decomposed by HF-H2SO4-HCl treatment followed by dissolution in 6M HCl before applying solvent extraction procedure. In Nb/Ta type of samples‚ Indium was separated from Nb and Ta by acid hydrolysis‚ involving fusion
