If we glance again at the classification proposed by Andrewes and Horder we are struck at once by the fact that no hard and fast differences in fermentative properties characterize the various groups, and that the authors prefer to have recourse to the most frequent habitat of the organisms and to chemical tests, rather than to confine themselves to the latter method alone. From what has been s...

The aim of this study was to determine the influence storage temperature and time on physicochemical parameters starch syrups recommended for winter feeding bee colonies. studies included commercially available three an inverted saccharose syrup that were stored at different temperatures: ca. 20 °C, 10–14 4 °C. Physicochemical fresh (immediately after purchase) 3, 6, 9, 12, 15, 18, 21, 24 month...

Abstract TiO2-C photocatalysts were prepared by hydrothermal synthesis using titanium tetraisopropoxide, saccharose and HCl of variable concentration. The have textural properties similar to those analogous bare TiO2 samples, but different crystalline phase composition; they only contain anatase instead an anatase-brookite-rutile mixture in TiO2. This reveals that carbon contributes the stabili...

Plants of maritime pine (Pinus pinaster Ait.) were acclimated for 2 years under ambient (350 μmol mol -1 ) and elevated (700 μmol mol -1 ) CO 2 concentrations ([CO 2]). In the summer of the second growing season, the plants were subjected to a soil drying cycle for 6 days. Drought reduced plant transpiration rate and net CO 2 assimilation rate (A) by about 80 %. Elevated [CO,] induced a s...
