Synthesis and Bactericidal Activity of Substituted Cyclic Acetals

Bacteria of the genus Azospirillum are among the most studied bacteria, stimulating the growth of plants and capable of associative interaction with many higher plants. They have a high adaptive potential to the negative external influences, like the lack of nutrients, salinity, lack of moisture. Compared with other rhizosphere microorganisms, Azospirillum have sufficiently high resistance to heavy metals [5]. They are capable of transforming selenium and gold compounds, changing their oxidation state and transferring them from soluble to insoluble less toxic forms [6, 7]. In recent years, it was shown that the use of Azospirillum in bioremediation improves the process and allows for better extraction of harmful substances [8].
