As such, the volume of AP in the cultures from 200 and
225 C HTL reactions was higher, 4.7% and 3.4% respectively, than
all the others which were at 3% AP or less (see Section 2.2.2). Inhibition
of growth of a consortium of algae by HTL-AP has been
reported previously at values above 0.5% (Zhou et al., 2013).
