This article systematically analysed the literature to assess the approaches and methods of protein determination and to provide an evidence-based conversion factor for nitrogen to protein that is specific to seaweeds.
Chemical defence against bacteria in the red alga Asparagopsis armata: linking structure with function
- N. Paul, R. Nys, P. Steinberg
- Biology
- 11 January 2006
Results indicate that halogenated metabolites of Asparagopsis armata may be important in reducing epiphytic bacterial densities, in a novel ecological test of algal natural products.
Total lipid and fatty acid composition of seaweeds for the selection of species for oil‐based biofuel and bioproducts

The results support macroalgae (seaweeds) as a biomass source for oil‐based bioproducts including biodiesel and quantified within species variation of fatty acids across locations and sampling periods supporting either environmental effects on quantitative fatty acids profiles, or genotypes with specific quantitative fatty acid profiles, thereby opening the possibility to optimize the fatty acid content and quality for oil production through specific culture conditions and selective breeding.
Comparative production and nutritional value of “sea grapes” — the tropical green seaweeds Caulerpa lentillifera and C. racemosa

Overall C. lentillifera has a high biomass production potential in monoculture and distinct nutritional properties that warrant a focus on its commercialisation as a new aquaculture product in tropical Australia and in Southeast Asia more broadly.
Effects of Marine and Freshwater Macroalgae on In Vitro Total Gas and Methane Production

The lack of relationship between the primary biochemistry of species and gas parameters suggests that significant decreases in TGP and CH4 production are associated with secondary metabolites produced by effective macroalgae, and Asparagopsis offers the most promising alternative for mitigation of enteric CH4 emissions.
Identification of bioactives from the red seaweed Asparagopsis taxiformis that promote antimethanogenic activity in vitro

- 21 March 2016
Asparagopsis taxiformis has potent antimethanogenic activity as a feed supplement at 2 % of organic matter in in vitro bioassays. This study identified the main bioactive natural products and their…
Seaweed-herbivore interactions at a small scale: direct tests of feeding deterrence by filamentous algae
- N. Paul, R. Nys, P. Steinberg
- Environmental Science
- 5 October 2006
This study demonstrates that resistance traits may also be important and more broadly utilised in filamentous species, and test the role of algal secondary metabolites in defence against herbivores without using artificial diets.
Feeding Preferences and the Nutritional Value of Tropical Algae for the Abalone Haliotis asinina
- Alex R. Angell, I. Pirozzi, R. de Nys, N. Paul
- Environmental SciencePLoS ONE
- 14 June 2012
The tropical H. asinina had strong and consistent preferences for the red alga Hypnea pannosa and the green alga Ulva flexuosa, but no overarching relationship between protein content (sum of amino acids) and preference existed, and it was demonstrated that preferences can largely be removed using carrageenan as a binder for dried alga.
Removing Constraints on the Biomass Production of Freshwater Macroalgae by Manipulating Water Exchange to Manage Nutrient Flux
The integrated culture of freshwater macroalgae with aquaculture for the purposes of nutrient recovery is a feasible solution for the bioremediation of wastewater and the supply of a protein resource.
