Antifouling potentials of extracts from seaweeds, seagrasses and mangroves against primary biofilm forming bacteria

Evaluation of tannin from Rhizophora apiculata as natural antifouling agents in epoxy paint for marine application

“…It is observed that the inhibition efficiency of TZn towards all target bacteria was increased as the concentration of TZn increased. Supportively, Prabhakaran et al [16] reported mangrove extracts showed higher activity of inhibition against the bacteria and suggested that this natural product has a potential source of antibacterial compounds.…”

“…It has been reported that further investigation with various concentration fractions of the extracts has to be done to see the effectiveness of the substance [16]. The effectiveness of biofilm agents depends on the concentration of mangrove tannin or zinc tannate in the application.…”

Bioactive Propensity of Macroalgae from the Andaman & Nicobar Islands

“…The antibiofilm nature of Ulva reticulata, Sargassum wightii and Halimeda macroloba has also been reported. 43 Recently, Yuvaraj and Arul 44 reported the antibiofilm activity of ten macroalgal extracts among this Sargassum wightii and Hypnea musiformis were prominent in inhibiting biofilm. Many of the secondary metabolites of macroalgae are well known for their cytotoxic activity.…”

“…The comparatively high inhibitory activity shown by the extracts of Caulerpa peltata in this study might be due to the presence of the cytotoxic compounds caulerpenyne or caulerpin and further evaluation is required to confirm this. The extraction process of bioactive compounds were varied by researchers and the most used solvents are acetone, benzene, butanol, [51][52] ethanol, 43,53 methanol 26 and water. 19 In our study an approach was made to analyse the effectiveness of the four solvents (MeOH, EtoAc, BuOH and H 2 O).…”

Autophagy Inhibition Enhances the Mitochondrial-Mediated Apoptosis Induced by Mangrove (Avicennia marina) Extract in Human Breast Cancer Cells

“…The chemical investigations of the plant have revealed the presence of terpenoids and steroids, naphthalene derivatives, flavones, iridoid glucosides, phenyl propanoid glycosides, flavonoids and abietane diterpenoid glucosides. Biological activities of the different extracts or isolated molecules from the plant species include antimicrobial [7,8,9], anti-inflammatory [10], antiplasmoidal [11], antioxidant [12], antifouling [13] and anticancer effect [6,14,15,16,17,18].…”
