Specifically, a significantly higher abundance of Gammaproteobacteria and Mollicutes was found on the first days of biofilm growth in spring (day 1 to day 4) and a higher abundance of Alphaproteobacteria during the same days of biofilm growth in winter. Our results demonstrated that distinct temporal patterns were observed in the sampled seasons. Biofilm communities growing in steel surfaces covered with an anti-corrosion paint and planktonic communities from the same location were also characterized. Sampling spanned 30-day periods in two distinct seasons (spring and winter). In this work, we used amplicon-based NGS (next-generation sequencing) and universal 16S rRNA bacterial primers to characterize the early biofilm bacterial communities growing on 316 L stainless steel surfaces in a Northern Portugal port. In particular the study of early biofilms, in which the bacterial cells communities first adhere to artificial surfaces, are crucial for the development of the subsequent biofilm communities. More specifically, it is not fully known if bacterial colonizers of artificial surfaces are similar or distinct in the different seasons of the year. Despite some recent research, the succession of bacterial communities colonizing artificial surfaces remains uncharacterized in some temporal settings. Marine biofilms are known to influence the corrosion of metal surfaces in the marine environment. 3Institute of Biomedical Sciences Abel Salazar, University of Porto, Porto, Portugal.2Departamento de Biologia, Faculdade de Ciências, Universidade do Porto, Porto, Portugal.1Centro Interdisciplinar de Investigação Marinha e Ambiental, Universidade do Porto, Matosinhos, Portugal.Sousa 1, Joana Azevedo 1, Adriana Rego 1,3, Pedro N.
