March 2021
The volcanic soils of Chiloé Island, Chile, have physical and chemical characteristics that affect their productivity. We report here a 16S rRNA gene analysis that characterizes the predominant microbial communities in volcanic soils of Chiloé either in the presence or absence of fertilization. The major phyla identified were , , and .

- The study uses density functional calculations to analyze four types of sapphyrins, focusing on their conformations and stability.
- The findings agree with experimental evidence, showing that TPS and TP2OS adopt an inverted conformation, while TP2SS and TP2SeS are more stable in the normal conformation.
- The relative stability of these conformers is linked to factors like planarity, aromaticity, steric repulsions from phenyl rings, and bond properties evaluated through AIM analysis.
