AB New viruses are one of the major health challenges that human society is facing during this century. One of themost promising solutions is searching for natural organisms or molecules with antiviral capacity, with emergingmicroalgae as a promising solution in recent years. Thus, in this work, the antiviral capacity of ten species offreshwater and marine microalgae was tested against three enveloped and non-enveloped bacteriophages(PhiX174, MS2 and Phi6), showing inhibition efficiencies ranging from 40 to 80% compared with control in-fections. Moreover, the PCA analysis revealed the influence of the microalgal cell wall on the different bacte-riophages’ inactivation capacity. Finally, the inactivation of the three bacteriophages in liquid cultures wasstudied using the microalgae Chlorella vulgaris and Thalassiosira weissflogii. These microalgae inactivated99.999% of the MS2 and Phi6, and 99.9% of PhiX174 after 72 h of cultivation, respectively. Additionally, T90values ranging from 7 to 12 h for PhiX174, 3 to 12 h for MS2 and 2.5 to 3 h for Phi6 were achieved by the twotested microalgae. These results highlight the potential of microalgae for the inactivation of viruses in waste-waters and as an outstanding source of antivirals.
