Abstract

Abstract: The community composition and distribution of early-stage (24 h) biofilm-forming bacteria on two different surfaces (glass slide and polystyrene plastic slide) at three different locations (Diu, Alang and Sikka) were studied using a culture-dependent and next-generation sequencing (NGS) approach in the Arabian Sea, Gujarat, India. The most dominant phyla observed using the NGS approach were the Proteobacteria among the sampling sites. Gammaproteobacteria class dominated both the surfaces among the sites and accounted for 46.7% to 89.2% of total abundance. The culture-dependent analysis showed Proteobacteria and Firmicutes as the dominant phyla on the surfaces within the sampling sites. During the initial colonization, hydrocarbon-degrading bacterial strains have also attached to the surfaces. The outcome of this study would be of great importance for targeting the early stage biofilm-forming and hydrocarbon-degrading bacterial isolates may help to degrade plastic in the marine environment. Graphical abstract: Unlabelled Image Highlights: Early colonizing bacteria were studied in-situ on plastic and glass surfaces. These bacteria were identified by culture-dependent and metagenomic approaches. The bacterial community over the glass and plastic surfaces was distinct. Most dominant phyla were Proteobacteria, Bacteroidota and Firmicutes . Few bacterial strains capable to degrade hydrocarbon compounds
