查询词典 one species

While the adsorptions of 1-propanol and 1-Br-propane at 100℃ give rise to 1-propoxy species, which mainly converted to propanal at higher temperature. IR spectrum arising from the interaction of propene with the catalyst at 100 ℃ shows the IR bands of allyl alcoholate and isopropoxy species. As the temperature was increased to 150℃, the bands ascribable to the adsorbed acetone and acrolein were observed. Based on these results, it is suggested that isopropoxy species is one of the intermediates for SOP to acrolein over MoPO/SiO〓 catalyst.

While the adsorptions of l-propanol and 1-Br-propane at 100 癈 give rise to 1-propoxy species, which mainly converted to propanal at higher temperature. IR spectrum arising from the interaction of propene with the catalyst at 100 癈 shows the IR bands of allyl alcoholate and isopropoxy species. As the temperature was increased to 150 癈, the bands ascribable to the adsorbed acetone and acrolein were observed. Based on these results, it is suggested that isopropoxy species is one of the intermediates for SOP to acrolein over MoPO/SiO2 catalyst.

The comparison of the predominant bacterial community structure in the gastrointestinal walls between Lutjanus sebae (Cuvier, 1816) and Ephippus orbis (Bloch, 1787) based on 16S rDNA PCR-DGGE fingerprint using a culture-independent method was conducted in the paper. The results showed that abundant bacterium were planted in the gastrointestinal walls of both marine finfish species, the similarity was above 50% in the community structures in the gastrointestinal walls with the highest similarity of 67% in the bacterial composition between the intestinal wall of Luljonus sebae and that of Ephippus orbis, and the walls of the stomach and the intestinal in one fish shared the same most predominant bacteria species, which might reflect the same aquaculture environment and the diet fed for both finfish species.
