Inhibition effect on the growth of
Phaedactylum tricornutum
(as presented by
chlorophyll concentration) [26]
cornutum
which is a representative of primary surface colonizers [25]. The
extract proved to be as effective as TBTO against the development of the foul-
ing microalga as shown in Fig. 1 [26].
