Title: Examining hydrogen peroxide-containing organelles in seaweeds
Seaweeds, particularly the red seaweed Asparagopsis taxiformis, produce and sequester bromomethanes, which are known for mitigating methane emissions in ruminants when used as a feed supplement. Bromomethane synthesis requires hydrogen peroxide (H2O2). We developed a staining assay utilizing 3,3′-diaminobenzidine (DAB) for identifying H2O2 in three groups of seaweeds (red, brown, and green), including intensely pigmented species. Our findings indicate the previously identified "gland cell" in Asparagopsis taxiformis, responsible for bromoform synthesis and retention, is a specialized large organelle rich in H2O2. Our study introduces an effective survey tool to identify promising seaweed species abundant in bromoform from diverse marine habitats.  more » « less

    Abstract The red algaAsparagopsis taxiformishas recently been recognized for its unique ability to significantly reduce methane emissions from ruminant animals when fed in small quantities. The main obstacle in using this seaweed as a methane‐mitigating feed supplement is the lack of commercially available biomass. Little is known about how best to grow this red alga on a commercial scale, as there are few published studies that have investigated the factors that influence growth, physiology, and overall performance. This study examined the effects of temperature and CO2enrichment on the growth, photophysiology, and concentration of bromoform, the secondary metabolite largely responsible for methane reduction inA. taxiformis. A series of single and multifactor closed culture experiments were conducted onA. taxiformiscollected, isolated, and cultured from populations in Southern California. We identified the optimal temperature range to be between 22 and 26°C, with significant short‐term stress observed below 15°C and above 26°C. Carbon dioxide addition resulted in increased performance, when accounting for growth per CO2use. In general, we observed the highest bromoform concentrations in algae with the highest growth rates, but these results varied among experiments. These findings indicate that through environmental control and by addressing limiting resources, significant increases in biomass production and quality can be achieved.

    Abstract Algal carbon‐to‐nitrogen (C:N) and carbon‐to‐phosphorus (C:P) ratios are fundamental for understanding many oceanic biogeochemical processes, such as nutrient flux and climate regulation. We synthesized literature data (444 species, >400 locations) and collected original samples from Tasmania, Australia (51 species, 10 locations) to update the global ratios of seaweed carbon‐to‐nitrogen (C:N) and carbon‐to‐phosphorus (C:P). The updated global mean molar ratio for seaweed C:N is 20 (ranging from 6 to 123) and for C:P is 801 (ranging from 76 to 4102). The C:N and C:P ratios were significantly influenced by seawater inorganic nutrient concentrations and seasonality. Additionally, C:N ratios varied by phyla. Brown seaweeds (Ochrophyta, Phaeophyceae) had the highest mean C:N of 27.5 (range: 7.6–122.5), followed by green seaweeds (Chlorophyta) of 17.8 (6.2–54.3) and red seaweeds (Rhodophyta) of 14.8 (5.6–77.6). We used the updated C:N and C:P values to compare seaweed tissue stoichiometry with the most recently reported values for plankton community stoichiometry. Our results show that seaweeds have on average 2.8 and 4.0 times higher C:N and C:P than phytoplankton, indicating seaweeds can assimilate more carbon in their biomass for a given amount of nutrient resource. The stoichiometric comparison presented herein is central to the discourse on ocean afforestation (the deliberate replacement of phytoplankton with seaweeds to enhance the ocean biological carbon sink) by contributing to the understanding of the impact of nutrient reallocation from phytoplankton to seaweeds under large‐scale seaweed cultivation.

    The inclusion Asparagopsis spp. into the diet of ruminant animals has produced compelling data regarding the mitigation of agricultural methane emissions. This reduction is achieved via the action of brominated halogenated compounds, predominantly bromoform, which act to inhibit methanogenic enzymes in ruminant digestion. As such, there is great interest in the mass cultivation of Asparagopsis for use as a dietary supplement for livestock. However, data are still lacking on the basic biology of Asparagopsis relating to factors that influence the synthesis of bromoform, the key bioactive compound of interest. One of the two precursors for bromoform biosynthesis is hydrogen peroxide, while the other is bromide, a naturally occurring ion in seawater. Hydrogen peroxide is generated internally within the alga and can be stimulated by abiotic stress. Currently, the influence of temperature and external hydrogen peroxide addition on bromoform dynamics have been explored. The aim of this study is to explore how the stimulation of hydrogen peroxide by the application of light stress influences the dynamics of bromoform precursor uptake and production, as well as how this may drive changes in bromoform concentration and the persistence of gland cells, the cellular structures where bromoform is stored. While provision of light stress significantly stimulated an increase in hydrogen peroxide production, bromide dynamics were also significantly influenced, resulting in net bromide release, rather than uptake. Further, bromoform concentrations in algal tissue immediately declined after exposure to high light, from 4.5% to 2% (dry weight), while gland cell abundance declined from 95% to around 60%. Here we present data for dramatic alterations in bromoform dynamics after exposure to moderate increases in light intensity. These findings are strongly applicable to commercial Asparagopsis cultivation and will contribute to optimising algal quality during cultivation and harvest.

    Abstract Molecular design ultimately furnishes improvements in performance over time, and this has been the case for Rh‐ and Ir‐based molecular catalysts currently used in transfer hydrogenation (TH) reactions for fine chemical synthesis. In this report, we describe a molecular pincer ligand Al catalyst for TH, (I2P2−)Al(THF)Cl (I2P=diiminopyridine; THF=tetrahydrofuran). The mechanism for TH is initiated by two successive Al‐ligand cooperative bond activations of the O−H bonds in two molecules of isopropanol (iPrOH) to afford six‐coordinate (H2I2P)Al(OiPr)2Cl. Stoichiometric chemical reactions and kinetic experiments suggest an ordered transition state, supported by polar solvents, for concerted hydride transfer fromiPrO−to substrate. Metal‐ligand cooperative hydrogen bonding in a cyclic transition state is a likely support for the concerted hydride transfer event. The available data does not support involvement of an intermediate Al‐hydride in the TH. Proof‐of‐principle reactions including the conversion of isopropanol and benzophenone to acetone and diphenylmethanol with 90 % conversion in 1 h are described. The analogous hydride compound, (I2P2−)Al(THF)H, also cleaves the O−H bond iniPrOH to afford (HI2P−)Al(OiPr)H and (HI2P−)Al(OiPr)2, but no activity for catalytic TH was observed.

    Abstract Great hope has been pinned on seaweed cultivation as being a potent way of removing CO2to reduce rates of sea surface warming and acidification. Marine heatwaves and nitrogen pollution in coastal ecosystems are serious current issues that need to be better understood to inform decision making and policy. Here, we investigated the effects of a simulated heatwave and nitrogen pollution on carbon sequestration by an important seaweed crop species and its phycosphere bacteria.Gracilaria lemaneiformiswas grown in ambient and high nitrogen conditions (14 and 200 μM L−1). Photosynthetic rate, seaweed biomass and particulate organic carbon accumulation were significantly increased in “high nitrogen‐no heatwave” conditions. In “ambient nitrogen heatwave” conditions, the expression of genes related to photosynthesis was down regulated and the seaweeds lost more dissolved organic carbon (DOC) to the surrounding water, resulting in more refractory dissolved organic carbon (RDOC). In “high nitrogen heatwave” conditions, photosynthetic gene expression was upregulated; bacterial abundance was also increased that can explain the reduced DOC and RDOC accumulation. The simulated heatwave reduced bacterial diversity while high nitrogen alleviated this effect. These findings suggest that the economically important algaG.lemaneiformismay lose more DOC and RDOC to nearshore waters during marine heatwave events, enhancing carbon sequestration, while nitrogen enrichment has a counteractive effect.
