Marine biofilms on artificial surfaces: structure and dynamics
TLDR
Overall, differences have been identified in species composition between biofilm and planktonic forms for both diatoms and bacteria at various exposure sites, and issues such as reproducibility, differences in exposure sites and biofilm composition may influence the outcomes.Abstract:
The search for new antifouling (AF) coatings that are environmentally benign has led to renewed interest in the ways that micro-organisms colonize substrates in the marine environment. This review covers recently published research on the global species composition and dynamics of marine biofilms, consisting mainly of bacteria and diatoms found on man-made surfaces including AF coatings. Marine biofilms directly interact with larger organisms (macrofoulers) during colonization processes; hence, recent literature on understanding the basis of the biofilm/macrofouling interactions is essential and will also be reviewed here. Overall, differences have been identified in species composition between biofilm and planktonic forms for both diatoms and bacteria at various exposure sites. In most studies, the underlying biofilm was found to induce larval and spore settlement of macrofoulers; however, issues such as reproducibility, differences in exposure sites and biofilm composition (natural multispecies vs. monospecific species) may influence the outcomes.read more

In situ generation of amphiphilic coatings based on a self-catalytic zwitterionic precursor and their antifouling performance
TL;DR: In this paper, a new zwitterionic precursor for easy fabrication of ZWitterionic groups containing amphiphilic antifouling coatings was developed. But the in-situ feature restricts its applicability, as acid or alkaline water must be used to circumvent this issue.

TL;DR: NucM is likely to increase the ability of cells to survive and persist in vivo, increasing the virulence of M. catarrhalis and potentially affecting the behaviour of other pathogens that co-colonise the otorhinolaryngological niche.
