“…For D. antarctica, no significant difference was found between males and females, which could indicate that both sexes use phlorotannins equally for protection. Phlorotannins are known to act as antioxidants, participate in UVR protection, and in general defence , Wang et al 2009, Onofrejová et al 2010, Steinhoff et al 2012). As we found no sex-specific differences in the concentration of these biochemical compounds it seems that both sexes of D. antarctica are equally fit to survive rafting along the coast of central Chile.…”

“…This variation has a direct impact on the chemical composition of each individual. For instance, one could expect that females might produce more phlorotannins, as this phenolic compound has repeatedly been proven to have a protective role, such as having high antioxidant activity in seaweeds (Li et al 2009, Wang et al 2009, Onofrejová et al 2010. Additionally, the concentration of pigments, which are essential for photosynthesis and photoprotection, can vary between sexes (Guillemin et al 2014).…”

Dispersal of dioecious floating seaweeds could be limited due to biological constraints. This study examined for benthic and floating populations (stranded individuals) of the rafting kelp Durvillaea antarctica whether male and female individuals cohabit within one holdfast. As a previous study had indicated colour differences between sexes, we also examined whether these colour differences are consistent and possibly related to pigment and phlorotannin concentrations. Our large-scale survey of rafted holdfasts and a small-scale survey of benthic holdfasts at two sites found that reproductive males and females do travel together in coalesced holdfasts, although this proportion is relatively low (5-17%). There were no sex-specific differences in pigment and phlorotannin concentrations, but there were significant differences between the two benthic populations. There was no relationship between the colouration of thalli and the concentration of pigments but there was a slight colour difference between vegetative and reproductive sexual stages. Based on these results we conclude that biological conditions are not the cause for the lack of genetic connectivity between D. antarctica populations from central Chile. Instead, we suggest that ecological processes, such as density-blocking and physical factors (i.e. currents and winds), limit the potential for successful rafting dispersal.

“…Carotenoids, astaxanthin, fucoxanthin and other compounds from seaweeds exhibit antioxidant and other activities and can be used by the food industry (Ngo et al, 2011;Pangestuti and Kim, 2011), while other pigments from marine bacteria, microalgae and plants can be used as natural food colorants (Holdt and Kraan, 2011;Baghel et al, 2014). Various phenolic compounds, tannins, terpenes etc., from seaweeds and other marine plants show antimicrobial and antioxidant activity (Kontiza et al, 2008;Onofrejova et al, 2010;Holdt and Kraan, 2011;Cox et al, 2013) same as the phenolics from terrestrial plants (Proestos et al, 2006).…”

Marine environment affords a plethora of bioactive compounds with unique properties and remarkable potential for biotechnological applications. A lot of those compounds can be used by the food industry as natural preservatives, pigments, stabilizers, gelling agents, and others, while others exhibit beneficial effects and can be used as functional food ingredients, nutraceuticals, dietary supplements and prebiotics. Interdisciplinary approach is required to increase our knowledge, explore the potential of marine environment and produce value-added food for all.

An ionic liquid-based ultrasonic-assisted extraction method has been successfully applied to the effective extraction of phenolic compounds from Laminaria japonica Aresch. Three kinds of 1-alkyl-3-methylimidazolium with different cations and anions were evaluated for extraction efficiency. The results showed that both the characteristics of anions and cations have remarkable effects on the extraction efficiency. In addition, the ionic liquid-based ultrasonic-assisted extraction procedure was also optimized on some extraction parameters, such as ultrasonic power, extraction time and solid-liquid ratio. Compared with the conventional solvent, the optimum approach gained the highest extraction efficiency within the shortest extraction time. Average recoveries of phenolic compounds were from 75.5% to 88.3% at three concentration levels.
