The authors regret that in the original version of this article, the culture collection strain ID numbers of the microalgae given in materials and methods Table 1 were not correctly assigned to the species names. The following revised Table 1 provides the correct strain ID numbers and information. The authors take the opportunity to note that the taxonomy of some of these strains is still under review (see “cf.” in Table 1). Recently, discussions have arisen regarding the correct taxonomy of CCCryo 194-04 (pers. comm. T. Leya, curator of CCCryo). Kawasaki et al. (2015) have recently revised several coccalean, oil-producing green algae and have assigned CCCryo 340b-08 (which is the same species as CCCryo 194-04) to the genus Macrochloris. On the other hand, it is currently being evaluated whether CCCryo 194-04 should be assigned to a different, still to be erected and published species within the genus Pleurastrum. The true taxonomy (and names) of some strains thus remain unclear at this time, and so the strain ID numbers containing the collection acronym listed above should be used to identify the microalgae used in this work. The authors would like to apologise for any inconvenience caused.
