“…In S. muticum, palmitic acid constitutes 21.5 % of the total fatty acids, and has been shown to have antimicrobial activity against bacteria and diatoms (Bazes et al 2009). Similarly free fatty acids extracted from Sargassum pallidum have considerable antimicrobial activity against bacteria, yeast and fungi, with glycolipids and neutral lipids demonstrating 'moderate' activity (Gerasimenko et al 2014).…”

“…Chloroform (Plouguerne et al 2008(Plouguerne et al , 2010 and ethanol (Hellio et al 2001;Silkina et al 2009) extracts from S. muticum have antimicrobial activity against several bacterial, fungal, and microalgal strains involved in marine biofilm formation and could be the basis of an antifouling product.

Marine seaweeds represent an abundant source of natural products and may harbour valuable chemicals. The brown seaweed Sargassum muticum is an invasive species to the coasts of the British Isles, mainland Europe and North America. Attempts at its eradication and control have generally not been successful, although time-consuming and costly. Commercial exploration of this biomass for food, fuel and pharmaceutical products could encourage its harvesting and control. Though S. muticum might be unsuitable as a source of biofuel due to high ash and water content, this rapidly growing macroalga has a naturally high content of antioxidants, carotenoids and phenols, including the well-known anti-cancer compound fucoxanthin, making this species a potential source of a range of pharmaceutically relevant materials.

“…The effectiveness of biocides towards phototrophic organisms can be tested as the degree of chlorophyll degradation (Silkina et al 2009;Underwood and Paterson 1993). When chlorophyll degrades, it forms a series of degradation products, the nature of which depends on the part of the molecular structure of chlorophyll affected.…”

Color measurements as a reliable method for estimating chlorophyll degradation to phaeopigments

et al. 2010

The application of biocides is a traditional method of controlling biodecay of outdoor cultural heritage. Chlorophyll degradation to phaeopigments is used to test the biocidal efficacy of the antimicrobial agents. In the present study, the usefulness of color measurements in estimating chlorophyll degradation was investigated. An aeroterrestrial stone biofilm-forming cyanobacterium of the genus Nostoc was chosen as test organism, comparing its different behaviour in both planktonic and biofilm mode of growth against the isothiazoline biocide Biotin T®. Changes in A(435 nm)/A(415 nm) and A(665 nm)/A(665a nm) and in the chlorophyll a and adenosine triphosphate (ATP) cell content were compared with the variations in the CIELAB color parameters (L*, a*, b*, C*(ab) and h(ab)). Our findings showed that both the phaeophytination indexes are useful in describing degradation of chlorophyl a to phaeopigments. Moreover, the CIELAB color parameters represented an effective tool in describing chlorophyll degradation. L* CIELAB parameter appeared to be the most informative parameter in describing the biocidal activity of Biotin T® against Nostoc sp. in both planktonic and biofilm mode of growth.

“…Diuron metabolites, notably DCPMU (1-(3,4-dichlorophenyl)-3-methyl urea), DCPU (1-(3,4-dichlorophenyl urea) and DCA (3,4-dichloroaniline) (Tillmanns et al 1978), have been detected in the UK (Gatidou et al 2003), Japan (Okamura et al 2003) and Spain (Martinez and Barcelò 2001). Several bioassays tests assessed the toxicity of Diuron, which is an inhibitor of photosynthesis (Konstantinou and Albanis 2004), while its principal aerobic and anaerobic degradation products, which generally show higher toxicity than the parent compound (Gatidou et al 2007), are a threat to several marine living organisms such as algae, crustacean, fishes, echinoderma, diatoms and mammalians (Tixier et al 2000;Bonnemoy et al 2004;Fernàndez-Alba et al 2002;Okamura et al 2002;Kobayashi and Okamura 2002;Hernando et al 2003;Huang et al 2005;Manzo et al 2006;Bellas et al 2005;Koutsaftis and Aoyama 2007;Silkina et al 2009;Giacomazzi and Cochet 2004); nonetheless, Diuron at 10 mg/L had no significant effect on sea-water aerobic cultivable microorganisms (Harino et al 2005). The recalcitrance of Diuron has been reported in bioassays using a ship-fouling diatom (Callow and Willingham 1996), in laboratory investigations conducted in marine seawater, where Diuron was not photodegraded by sunlight irradiation (Harino et al 2005), its concentration was not reduced over 42 days of aerobic incubation (Thomas et al 2002), nor it was in anaerobic marine sediments, in which half-lives of 14 days were calculated (Thomas et al 2003).…”

Biological fate of Diuron and Sea-nine® 211 and their effect on primary microbial activities in slurries of a contaminated sediment from Venice Lagoon

The individual fate of the industrial booster biocides Diuron (3-(3,4-dichlorophenyl)-1,1-dimethylurea) and Sea-nine® 211 (4,5-dichloro-2-n-octyl-4-isothiazolin-3-one) in a marine sediment of Porto Marghera (Venice Lagoon, Italy) was investigated, under anaerobic and aerobic conditions, in slurry-phase microcosms consisting of sediment suspended in its own overlaying water, i.e. under biogeochemical conditions which closely mimic those occurring in situ. Biocides were singly supplied as methanol solutions to a final concentration of 50 mg/kg of dry sediment. No Diuron degradation occurred throughout 3 months of incubation under any of the conditions tested. Conversely, Sea-nine®211 was promptly and completely degraded, regardless of the presence of oxygen. Under anoxic conditions, neither sulphate reduction nor methanogenesis occurred significantly in the non-amended microcosms, probably because of the very low availability of substrates in the actual site sediment and water employed. In contrast, methanogenesis occurred in the biocide amended microcosms where methanol was supplied as the carrier for biocides. No sulphate consumption was observed in the same microcosms. The large methane production observed in the parallel biocide-free control microcosms supplemented with methanol suggested that methylotrophic methanogens were the main compounds responsible for the detected activities. Diuron was found to intensify methane production, probably because it exerted an inhibitory effect on some competitors of indigenous methylotrophic methanogens.
