The aim of this work was to study the fermentation of whey for the production of L(+) lactic acid using Lactobacillus casei. The effect of different process parameters such as pH of the medium, temperature, inoculum size, age of inoculum, agitation and incubation time was monitored to enhance the lactose conversion in whey to L(+) lactic acid. Fermentations were performed without any pH control...

Sorption experiments using the dead biomass of Spirogyra species, for copper removal were carried out to study the influence and optimization of the biosorption of Cu (II). The effect of pH (1.0 10.0), initial metal ion concentration (1 100ppm), different contact periods (30 180 min), varying temperature (25 – 50 oC) and varying biomass quantities (0.5,1.0,1.5 and 2.0 g) were also examined. It ...

The process parameters, temperature, pH and substrate concentration, were optimized for the production of gentamicin using Micromonouspora echinospora. Experiments were carried out according to central composite design in response surface method. The optimum conditions for the maximum production of gentamicin were found to be: temperature – 31.7C, pH – 6.8 and substrate concentration – 3%. At t...

The pH control process has been used in industry in a wide number of applications. Its dynamics are highly nonlinear. The pH control process is subjected to uncertainties of mathematical model describing the kinetics changes of chemical process and the external disturbances. The pH control process using the PID control technique will be investigated in this paper. The setting and adjustment of ...

A methylene-blue-sensitized polymer blend of polyvinyl alcohol and polyacrylic acid is fabricated and tested for holographic recording. It was found to have good characteristics such as high sensitivity, storage stability, ease of fabrication, and environmental stability. Optimization of the ratio of polyvinyl alcohol/polyacrylic acid, the sensitizer concentration, pH, energy, diffraction effic...

γ-Proteobacterium JB, an alkali-tolerant soil isolate, produced laccase (8X10 nkat/L) in M162 medium. The optimization of process conditions (pH, incubation time, agitation, and CuSO4 concentration) for laccase production during submerged fermentation was carried out using response surface methodology (RSM) based on a central composite design (CCD). Maximum laccase production achieved was 7.4 X...
