Vanadium (V) is a first-row transition metal ion that acts as a phosphatase inhibitor with a wide variety of biochemical and physiological functions. The ability of vanadium to form stable polyoxovanadates (POVs) and organometallic complexes has attracted attention for studying the properties and effects of these compounds in various biological systems. In my research, I used the bacterium species Mycobacterium smegmatis (M. smeg), which has undergone reclassification and is now classified as Mycolicibacterium smegmatis. Despite the taxonomic change, both the previous and current classifications use the same abbreviation, M. smeg. I also carried out some studies in Mycobacterium tuberculosis (M. tb). In my work, I explored the properties of several types of vanadium compounds including salts, oxometalates, and coordination complexes to investigate how they impact cellular growth.
