Laboratory studies were conducted to know about the effect of pH of sodium hydroxide solution and its temperature for absorption of SO2 contained in flue gases. it was found that the pH of the solution should be alkaline for good absorption of SO2. Because of the acidic nature of SO2, the reaction is restricted in acidic solution. and maximum absorption of SO2 was found in temperature range between 20-25°C. At higher temperature reversible reaction may take place and partially formed product may be changed back into initial reactants.Keywords

Ultrasonic speed have been measured in pure and binary mixtures containing copper soaps derived from groundnut and sesame oils in 20 % and 40% methanol benzene mixture. From these values, the specific acoustic impedance, adiabatic compressibility, intermolecular free length, apparent molar compressibility, molar sound velocity, primary solvation number have been calculated. The results have been fitted to Masson equation. The results have been explained on the basis of intermolecular interactions.Keywords

The demand of proteases is increasing regularly because of their numerous applications in the biotechnological industries. It promotes isolation and identification of potent protease producing fungi from soil samples. Therefore, the objective of the present investigation was to screen soil fungi in submerged fermentation (SmF) for detection of hyperproducer isolate and production of protease in SmF. Fungal strains from three diverse soil samples were isolated on potato dextrose agar (PDA) plates by serial dilution agar plate technique, purified by point inoculation and twelve isolates utilized for production of extracellular protease in SmF. Results were examined both in terms of protease activity and specific activity. Among all 12 fungal strains, isolate S2St1 (isolated from medicinal garden soil) exhibited maximum activity of protease (256.63 ± 3.18 U/ml/min) at 72 h of incubation. Isolate S2St1 was identified as potent producer of protease in SmF. Further this isolate can be used for production of large quantity of protease in SmF within very short time period of 3 days.Keywords

Proteases are one of the most significant groups of commercial enzymes and contribute 60% of the world enzyme market. The choice of proteases is the microbial proteases due to their versatility, stability and distinctive properties. Today, microbial proteases are utilized in various industries viz., meat processing, ripening of cheese, detergents, textile, recovery of silver from photographic image etc. Therefore, the present study was undertaken to increase the protease production from wild and mutagenic strain of Aspergillus sp. Wild and mutagenic strain of proteolytic soil fungus Aspergillus sp. was used for optimization study. Different parameters (nitrogen, carbon sources, temperature, pH and incubation time) were optimized in submerged fermentation (SmF) for enhanced protease production. Wild strain demonstrated highest protease activity at pH 10.0 after 48 h of incubation at 37 °C in the medium containing glucose as carbon source and yeast extract as nitrogen source whereas optimum protease activity from mutagenic strain was found at pH 10.0 after 94 h of incubation at 37 °C in the medium containing fructose as carbon source and peptone as nitrogen source. Protease production was increased from wild and mutagenic strain of Aspergillus sp. after parameters optimization in SmF.Keywords

Colloid chemical behavior and micellar characteristics of Cu (II) soaps derived from sesame and soyabean oils, (fresh oils and treated for 15 and 60 min.) at high temperature in benzene have been investigated and verified by ultrasonic velocity measurement. From these values, the specific acoustic impedance Z, adiabatic compressibility βad, intermolecular free length Lf, apparent molar compressibility Øk, molar sound velocity R, primary solvation number Sn have been calculated. The results have been analyzed in terms of Masson's equation. The results have been explained on the basis of solute-solvent interactions. The decrease in β and Lf with increasing concentration of the complex is indicating that there is sufficient solute- solvent interaction due to which micellar alignment is considerably affected.Keywords

Ultrasonic speed and density parameters have been measured in binary and ternary systems containing complexes of copper surfactants (caprylate, caprate, and laurate) with substituted 2-amino-6-chloro benzothiazole in 80% and 40% benzene-methanol mixture at constant temperature using thermostatic water bath. From these values, the specific acoustic impedance Z, adiabatic compressibility , intermolecular free length Lf, apparent molar compressibility φk, have been calculated. The results have been explained on the basis of intermolecular interactions and indicate that there is sufficient solute-solvent interaction due to which micellar alignment is considerably affected. The decrease in adiabatic compressibility β and intermolecular free length Lf of the copper surfactant complex solution with increasing concentration of copper surfactant complex in 80% and 40% benzene methanol has been observed which suggest that the non-polar long chains or lypophilic segment of the molecule in the solution are enveloped by a layer of solvent molecules bound and oriented towards lypophilic end. The orientation of the solvent molecules around the solutes may be due to the influence of electrostatic fields of solutes and results in the increase in the internal pressure and in lowering the compressibility of the solution i.e. the solution becomes harder to compress.Keywords
