  In prokaryotes, the autotrophic population within the bacteria kingdom presents great biotechnological potential. For taxonomic analysis of species, the sequence encoding the small subunit ribosomal RNA gene (16S rRNA) is currently the most reliable technique for phylogenetic bacterial classification. Sequencing can define the population diversity and ecological importance within a habitat. The study of autotrophic bacteria population dynamics in a photobioreactor using a carbon and nitrogen free culture medium could provide information about succession dynamics under controlled conditions. The aim of this study was to identify the bacterial populations present in a photobioreactor by 16S rRNA amplicon sequence comparison from samples taken at 0, 7, and 14 fermentation days. Most of the identified clones were described to the level of genera from the following phyla: Proteobacteria (4.. View More»
