The antifouling performance of a zwitterionic sulfobetaine-hydroxyethyl-containing polymethylmethacrylate ter-co-polymer (PSBM) is evaluated against three photosynthetic strains, namely Chlorella sp., Nannochloropsis and Arthrospira maxima. PSBM-coated (PMMA) surfaces displayed significantly reduced propensity for biofilm formation compared to rough untreated controls, leaving clean after 7 days exposure. A tribological approach was adopted estimate the long-term durability PSBM coating. Repeated cycles exposure A. maxima biomass subject coating stress continuous challenges. After several cycles, maintains higher efficacy than PMMA surface, suggesting stability high potential in photobioreactor applications.

Cyanobacteria biomass sources have the potential to contribute replacement of fossil fuels and reduction in global warming by sustainable conversion atmospheric CO2 into biofuels high-value chemicals. cultivation photobioreactors (PBRs) results biofouling on their transparent inner walls, which reduces photosynthetic efficiency productivity. While cyanobacteria PBRs is recognized as a significant operating challenge, this review draws attention lack studies antifouling strategies for involving discusses several areas related fouling mechanisms PBR materials, require further investigation. These include an in-depth analysis conditioning films, role pili EPS gliding adhesion, revisions existing theoretical models predicting material properties that affect adhesion. We use knowledge from marine, medical, industrial management help identify combat PBRs, we applicability various bioinspired physical chemical strategies, well genetic engineering approaches prevent biofilm formation PBRs.
