Nitrate reductase activity in green macroalgae as an environmental indicator of...
Madeira, Hélder T.; Aníbal, Jaime; Carvalho, Liliana F.; Esteves, Eduardo; Veiga-Pires, C.Temperature and salinity changes can affect nutrient assimilation dynamics in primary producers. Green macroalgae use nitrate as a main source of nitrogen for their metabolism. Nitrate needs to be reduced by nitrate reductase, before amino acids synthesis. Our aims were to study the effect of temperature and salinity changes on nitrate reductase activity (NRA) in Ulva rigida and Enteromorpha clathrata, and to a...
Macroalgae mitigation potential for fish aquaculture effluents: an approach cou...
Aníbal, J.; Madeira, Hélder T.; Carvalho, Liliana F.; Esteves, E.; Veiga-Pires, C.; Rocha, CarlosAquaculture effluents are rich in nitrogen compounds that may enhance local primary productivity, leading to the development of algae blooms. The goal of this study was to assess the potential use of naturally occurring green macroalgae (Ulva and Enteromorpha) as bioremediators for nitrogen-rich effluents from a fish aquaculture plant, by evaluating their respective uptake dynamics under controlled conditions. ...
