“…A papaína é enzima proteolítica de origem vegetal presente nas folhas e nos frutos do mamão que possui atividade associada à clivagem de ligações peptídicas (LEITE et al, 2012). Com ação anti-inflamatoria, bactericida, bacteriostática, desbridante, aceleradora e modeladora do tecido de granulação e dos processos de cicatrização tecidual, a papaína possui uma ampla faixa de aplicações na indústria alimentar, como amaciante de carnes, fabricação de cervejas, na indústria de lacticínios e panificação, remoção de cárie dentária, constituinte de cosméticos e detergentes e tratamento de feridas (PERES et al, 2015;RAŠKOVIC et al, 2015).…”

“…In the search for a highly efficient, easily processable, low-cost antifouling strategy, research has been performed from many perspectives, including material science and ecology, in recent years [ 9 , 10 ]. However, traditional marine antifouling techniques, which include bactericide coatings, antifouling paints, bionic material, and artificial membrane construction, have one or more unavoidable drawbacks, including recolonization, unacceptably high cost, and secondary pollution [ 11 , 12 , 13 , 14 , 15 ]. Therefore, there is an urgent need to develop novel environmentally friendly and non-toxic marine biofilm inhibitors.…”

Marine biofouling is a worldwide problem in coastal areas and affects the maritime industry primarily by attachment of fouling organisms to solid immersed surfaces. Biofilm formation by microbes is the main cause of biofouling. Currently, application of antibacterial materials is an important strategy for preventing bacterial colonization and biofilm formation. A natural three-dimensional carbon skeleton material, TRP (treated rape pollen), attracted our attention owing to its visible-light-driven photocatalytic disinfection property. Based on this, we hypothesized that TRP, which is eco-friendly, would show antifouling performance and could be used for marine antifouling. We then assessed its physiochemical characteristics, oxidant potential, and antifouling ability. The results showed that TRP had excellent photosensitivity and oxidant ability, as well as strong anti-bacterial colonization capability under light-driven conditions. Confocal laser scanning microscopy showed that TRP could disperse pre-established biofilms on stainless steel surfaces in natural seawater. The biodiversity and taxonomic composition of biofilms were significantly altered by TRP (p < 0.05). Moreover, metagenomics analysis showed that functional classes involved in the antioxidant system, environmental stress, glucose–lipid metabolism, and membrane-associated functions were changed after TRP exposure. Co-occurrence model analysis further revealed that TRP markedly increased the complexity of the biofilm microbial network under light irradiation. Taken together, these results demonstrate that TRP with light irradiation can inhibit bacterial colonization and prevent initial biofilm formation. Thus, TRP is a potential nature-based green material for marine antifouling.

“…Biofouling is the term to define undesired plants and animals which attach and grow on submerged artificial static or mobile in seawater. The attachment and colonization of life organisms has a deleterious impact on most offshore submerged structures [1][2][3]. Moreover, the biological process due to biofouling metabolism could yield detrimental effects on ships such as decreasing the time frequency of dry-docking operation, increasing the frictional resistance, and losing of corrosion resistance [4][5][6][7].…”

Antifouling paints are applied to prevent the growth of marine biofouling. In Indonesia, that paint is widely used for ship which commonly used copper-based biocide. In fact, there is no or little comprehesive studies on antifouling paint in Indonesia compared to other tropical countries. In this study, the evaluation of the performance for antifouling paint was carried out where anticorrosion paint and bare steel were also studied as references. The measurement of corrosion rate on steel was conducted by weight loss method. The panels containing specimens were exposure up to 1-month for immersion in different depth of sea up to 3 meters. Seawater parameters consisting of temperature, pH, salinity, conductivity and dissolved oxygen were measured as well as coating properties. The results showed both surfaces of anticorrosion paint and steel specimens covered by biofouling, but not on antifouling paint. There also is not much different in antifouling paint properties before and after exposure in various depth of sea. The reduction of thickness for antifouling paint is apparently predominant to be affected by sea current. The magnitude of corrosion rate on bare steel is almost the same in different depth of sea which took place due to the effect of dissolved oxygen and biofouling. In the future, the comparison of the paints perfomance all local regions is necessary to be conducted in all local regions of the Indonesia.
