摘要

Abstract

Parietochloris incisa is an arachidonic acid-rich snow green alga. The main physiological profiles

such as ash free dry weight (AFDW)

chlorophyll

carotenoid

protein and total fatty acids (TFA)

in this alga exposed to old culture supernatant (OCS) at the decline phase or its crude ethyl acetate extracts (CEAE) were investigated by using tubular photobioreactors of different diameters. Results showed that both OCS and CEAE had strong inhibitory effect on the above physiological parameters. The longer the culture was exposed to OCS and the more CEAE were added into the algal culture

the more the above physiological properties were inhibited. Arachidonic acid (AA)

the dominant component of fatty acids in this alga

was also seriously inhibited with respect to total TFA

AFDW of cell mass

or culture volume

due to a probable reduction of enzymes activities catalyzing chain elongation from C18; 1ω9 to AA. These results incontestably evidenced that some CEAE dissolving substances existing in OCS. like auto-inhibitors

inhibitedP. incisa growth through feedback. Hence

any efficient removal of auto-inhibitors from algal culture to decrease their bioactivity could be good for maximal production of desired products like AA.
