STEROL AND FATTY ACID COMPOSITIONS OF A MARINE ALGA BRYOPSIS PENNATA (BRYOPSIDOPHYCEAE, CHLOROPHYTA)

STEROL AND FATTY ACID COMPOSITIONS OF A MARINE ALGA BRYOPSIS PENNATA (BRYOPSIDOPHYCEAE, CHLOROPHYTA)

Pakistan Journal of Pharmaceutical Sciences 7(1): 73-82, January, 1994

This is a major pest algae in home salt water aquaria.

Folks have been using fluconazole to treat it.  Apparently the theory is that it’s acting in some way to block ergosterols from use or production, etc.

This article actually ID’s a few green algae with Egosterol contents, which is apparenltly more common in fungi:

Four sterols were isolated from the methanolic extract of Bryopsis pennata. One of them with cholesta skeleton was found as major constituent (78.12%), while three others with ergosta skeleton were present in traces (5-9%, Table 1). Ergosterol has been detected in Chlorella candida and C. nocturna, ergost-7-enol in C. ellipsoidea and C. saccharophila and ergost-5-enol in C. ernersonii and C. fusca (Patterson, 1971). Chlorella ellipsoidea also accumulates 5α-ergosta-8, 14-dien-3β-ol in the presence of a sterol inhibitor (Dickson et al, 1972). A variety of sterols with ergosta skeleton are found in green algae.
