Special Issue Information

Dear Colleagues,

The sea covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. Bacteria are found at all depths in the seawater column, and in the sediments; some are aerobic and others anaerobic. Bacteria in seawater are the primary contributors to ocean productivity, biomass, and diversity. They are the core drivers of ocean biogeochemical cycles, control the emission of radiatively active gases, and constitute the foundations of many marine ecosystems.

On the positive side, bacteria in seawater fundamentally influence the ocean's ability to sustain life on Earth. However, some bacteria living and transported in seawater could also threaten animal and human health. Therefore, bacteria, with both beneficial and detrimental roles in the seawater environment and human society, have many characteristics that still need our in-depth understanding. Yet, our knowledge about their biology is assumedly limited to the minority that have been successfully cultured. Therefore, a better understanding of uncultivated taxa may improve our understanding of bacteria in seawater.

This Special Issue welcomes any studies about bacteria in seawater, as long as they focus on an in-depth understanding of a particular question. Potential topics include but are not limited to: special life processes of marine bacteria, metabolism of marine bacteria, active substances from marine bacteria, pathogenic marine bacteria, evolution of marine bacteria, isolation and culture of marine bacteria, phage in marine bacteria, etc.

Epoxy resin has been frequently used as a coating paint for anticorrosion protection because of its excellent chemical properties. However, the long-term succession of bacteria colonizing coatings surfaces in the different seasons of the year remains uncharacterized. In this work, amplicon-based 16s rDNA sequencing was used to characterize the tempol change of bacterial communities growing on the epoxy resin surfaces. The results showed that bacterial diversity indices on spring and autumn immersion samples were higher than that of the samples immersed on summer and winter samples. Proteobacteria was found to be the dominant bacteria of all different seasons and accounted for 57.9% of the total sequence. Gammaproteobacteria and Alphaproteobacteria were the dominant classes in all of the samples, whereas the most abundance bacteria at the genus level had the significant differences with a change of season. Firmicutes also displayed a distinct temporal change pattern in that it was the second abundance in the summer and autumn samples, but had a marked decrease in the other season samples. These results demonstrated that bacterial community composition underwent obvious changes over the distinct seasons of a year. This study will be helpful for the seasonal change of bacterial diversity and development of corrosion-resistant paints. Full article
