Abstract
Seaweeds contain a myriad of nutrients and bioactives including proteins, carbohydrates
and to a lesser extent lipids as well as small molecules including peptides, saponins, alkaloids and
pigments. The bioactive bromoform found in the red seaweed Asparagopsis taxiformis has been
identified as an agent that can reduce enteric CH4 production from livestock significantly. However,
sustainable supply of this seaweed is a problem and there are some concerns over its sustainable
production and potential negative environmental impacts on the ozone layer and the health impacts
of bromoform. This review collates information on seaweeds and seaweed bioactives and the
documented impact on CH4 emissions in vitro and in vivo as well as associated environmental,
economic and health impacts
