two soil samples were air-dried at room temperature for 8 h in a laminar flow cabinet. Figure 3. Phylogenetic tree based on the 16S rRNA gene sequences using neighbor-joining method with 1,000 ...

The hydrazones were obtained in the usual fashion by reaction of the carbonyl group (C16) with selected hydrazines. The 13 C NMR data showed the characteristic signal of C=N group at 162-174 ppm. The ...

The dichloromethane extract prepared from the underground parts of Eleutherine bulbosa (Miller) Urban (Iridaceae) showed strong activity in the direct bioautography assay with the phytopathogenic ...

The stoichiometric constants were fixed to correspond with the assumed stoichiometries of the reactions considered and the Henry constant for hydrogen was also obtained from the literature.
