Quinacrine was used to visualize the intracellular pH changes in the yeast strain Saccharomyces cerevisiae RXII occurring after exposure to four recently-synthesized lysosomotropic drugs: DM-11, PY-11, PYG-12s and DMAL-12s. The cells took up quinacrine, mostly accumulating it in their vacuoles. DM-11 and PY-11 gave rise to diffuse quinacrine fluorescence throughout the cells, with the vacuoles staining to a somewhat greater extent than the cytosol. This quinacrine-detected overall acidification of the cell interior is very probably caused by blocking of plasma membrane H+-ATPase. PYG-12s gave rise to a strong vacuolar accumulation of the dye. Like the vacuolar ATPase inhibitor bafilomycin A1, DMAL-12s strongly lowered the intensity of quinacrine fluorescence. Owing to its low pKa, it can penetrate rapidly into the cells and may inhibit vacuolar H+-ATPase and prevent quinacrine-detectable vacuolar acidification without causing strong cell acidification. Since these drugs were found to penetrate into the cells, their lack of effect may reflect a higher resistance of both plasma membrane H+-ATPase and vacuolar ATPase to the drugs. Our data indicate that the lysosomotropic drugs under study have a dual action. On entering the cell, they cause intracellular acidification, very probably by inhibiting plasma membrane H+-ATPase and curtailing active proton pumping from the cells. Furthermore, they interfere with the function of V-type ATPase, causing vacuolar alkalinization and eventually cell death.

Aerobic sludge digestion in the presence of Fenton's reagent and hydrogen peroxide was examined. Fenton's reagent considerably improved the aerobic digestion process in comparison with hydrogen peroxide as well as classical aerobic digestion. Application of Fenton's reagent also led to improvement of settling and dewatering properties of sludge and much better clarity of supernatant. Its drawback, however, is the formation of chemical precipitate and an apparent decrease in pH which might inhibit biochemical processes important for aerobic digestion efficiency.

nr 3
The process of sludge digestion using hydrogen peroxide as the only oxidizing agent was carried out. It was pointed out that the application of H2O2 to the digestion process is possible provided that aerobic conditions of the process are strictly controlled in the course of the process. Since H2O2 should be added frequently into the digestion chamber it is highly recommended to supply the digestion chamber with the aeration system. It was shown that H2O2 may also be used to upgrade putrescibled sludge, what is especially important in the break-down events and when long-term storage is needed.

On the basis of the results of 13 year strict summer experiments on the dynamics of pH of soils which were unlimed (acidification) or limed (reacidification) on permanent grassland on two different mineral soils three phases differing in the average rate of pH change (∆pH/year) are presented. Phase III (about 10 years after liming) had the fastest changes. The rate of reacidification exceeded the reate of acidification. The increased efficiency of nitrogen compounds mineralization nitrification was accompanied by an increase in the rate of pH changes.

The pH changes of the soils formed as a result of reclamation of the sand-pits

The alluvial soils in the Bóbr river valley, devastated by sand and gravel exploitation, were reclaimed for agricultural use. After reclamation treatment, the newly formed soil was very acid. Application of 5 Mg/ha lime elevated soil pH to 6-7, but during the following years, soil pH dropped again by about one half of the pH unit a year. Rapid drop in the pH level can result both from geological and soil-forming processes. Efficiency of mineral fertilizers applied in various combinations did not give the expected results and the yield of cultivated plants was not satisfactory. Mineral fertilization in various combinations did not result in the expected yield levels.
