In this study, two different Winogradsky columns were prepared from muddy waters collected from Lake Akkaya (Nigde-Turkiye). Acetate was used as substrate in one of two mineral media in order to understand its impact on microbial inoculant from column under light and at room temperature for metagenomic studies. The results indicated that, the supplementation of acetate limited the growth of several members of the Proteobacteria phylum and reduced overall microbial diversity. Conversely, it has promoted the growth of various phototrophic and photoheterotrophic bacteria, particularly purple non-sulfur photosynthetic bacteria. In the absence of acetate, the most dominant bacterial species were Phyllobacterium members (34.97%), Aquimonas (13.32%), and Pandoraea (9.78%) respectively. In the acetate-supplemented medium, Rhodoplanes (35.15%), Pelolinea (25.53%), and Tiocapsa (6.87%) were predominant. These findings suggest that acetate promoted the growth of photosynthetic purple bacteria capable of utilizing aromatic compounds, indicating potential environmental benefits. Furthermore, acetate-supplementation may improve the efficiency wastewater treatment processes. Keywords : Acetate, Metagenomics, Microorganisms, Wastewater, Environment
