A flexible sensor with conducting polyaniline layer for detecting pH value based on the impedance measurement is fabricated and demonstrated in this study. The pH sensor consists of an interdigital electrode array on a flexible printed circuit and a thin-film polyaniline as the sensing layer. As the conductivity of polyaniline depends on the redox state, the impedance change of the polyaniline after it has reacted with different pH value solutions works as the sensing mechanism. In order to

. In this study, we investigated the optimal parameters for SSF of soybean meal by Lactobacillus species and Clostridium butyricum. The results showed that two days of fermentation was sufficient to increase the viable count of bacteria, lactic acid levels and degradation of soybean protein in fermented soybean meal at the initial moisture content of 50%. The pH value, lowering sugar content and oligosaccharides in fermented soybean meal, was significantly reduced at the initial moisture content of

system with a medium pressure UV lamp the optimal doses of SP and Fe2+/SP ratio were 200 mg/dm3 and 0.33, respectively at pH 3 and 20 minutes reaction time. In both cases, at described conditions total visual discoloration was achieved. Better results of colour removal (concentration of Acid Green 16 was in the range of 0.64-0.96 mg/dm3) were achieved when the initial pH value equalled 3.0 than at initial pH value of 4.0 (concentration of Acid Green 16 was in the range of 0.80-6.87 mg/dm3).

. fumigatus MS16 under solid-state (SSF) and submerged fermentation (Smf).
The pH value of the medium influences the production of an enzyme by regulating the solubility of the nutrients, the permeability of the cell membrane, and ionization of amino acids and/or proteins. Usually, fungal strains grow better under acidic conditions; A. fumigates MS16 did not show any exception, indeed a value of 5 as initial pH of the medium favored the production of pectinase (Fig. 4) and pH 6 spurred xylanase
