“…Meanwhile, they accept the idea of using qualitative fatty acids composition as a taxonomic feature of particular species of Chlorella, they presented many explanations of the variability in qualitative fatty acids composition. For example, they revealed the presence of the fatty acids 15:0, 17:0 and 17:1 as results of culture contamination with bacteria, in agreement with others (De Mort et al, 1972;Wacker et al, 2002). Also, they explained the presence of the fatty acids 20:0, 20:1 and 20:2 on the basis of the presence of impurities with similar retention time in GLC which agreed with the results obtained by Antonyan et al, (1986) and Homova et al, (1986).…”

Chlorophyll-a content of autotrophic cells of Chlorella vulgaris was double that estimated in heterotrophic cells, while chlorophyll-b content of autotrophic cells was nearly half the value recorded for heterotrophic cells. Carotenoids content of heterotrophic cultures decreased by 30.82% compared to that value of autotrophic cells. There was a slight decrease in the protein content of C. vulgaris under heterotrophic conditions. When the composition of total free amino acids and proline of C. vulgaris grown under autotrophic conditions is compared to that grown heterotrophically, it was observed that a significant increase in total free amino acids and proline in heterotrophic cultures. The percentage of most fatty acids of heterotrophic cells was relatively higher than autotrophic ones. There was no qualitative difference between autotrophic and heterotrophic cultures, except for the fatty acid 16:02 which was absent under autotrophic conditions.

“…Our results showed that Chlorella vulgaris has quite a simple qualitative fatty acids composition compared to other chlorophycean species. The qualitative composition of fatty acids varied not only at species level, but also varied in different phenotypes of the same species of Chlorella (Nichols, 1965;De Mort et. al., 1972;Antonyan et.…”

“…The composition under air was similar to those of most diatoms, showing a predominance of 14:0, 16:0, 16:1 and 20:5 (n‐3) (eicosapentaenoic acid: EPA). 10–14 These four acids accounted for 73% of the total fatty acids of this diatom. The fatty acid 16:1 in most diatoms was particularly abundant compared with green algae and cryptomonads.…”

A highly CO2-tolerant diatom, Thalassiosira weissflogii H1, enriched from coastal sea, and its fatty acid composition

SUMMARY: A marine plankton‐net sample containing 18 genera with 26 species of diatoms and one genus with two species of dinoflagellate collected from the surface water of Seto Inland Sea was used for an enrichment culture under bubbling 10% CO2 in air, and a 10% CO2‐tolerant microalga was isolated and identified as Thalassiosira weissflogii H1. There was no significant difference between the growth rates and maximum growth yields of this diatom under bubbling air, 5% CO2 and 10% CO2, but the growth rate and maximum growth yield under 20% CO2 markedly decreased. The percentages of EPA and DHA for the total fatty acids in cells under 5–20% CO2 were lower than those under air. However, the ratios of EPA to algal cells – dry weight under 5% CO2, 10% CO2 and 20% CO2 were 0.76, 0.36 and 0.37 (% of dry weight), respectively, as compared with 0.18 under air. There was no significant difference in DHA contents (0.05 under air, 0.13 under 5% CO2, 0.05 under 10% CO2 and 0.09 under 20% CO2), with or without bubbling CO2. The polysaccharide content in the cells under 10% CO2 was higher than that in the cells under air. This study is the first report on a highly CO2‐tolerant diatom.

“…The C18, C20 and C22 polyunsaturated fatty acid (PUFA) components were major constituents in the microplanktonic dinoflagellate, a finding similar to that observed in diatoms by others researchers (e.g. Demort et al, 1972;Ben-Amotz et al, 1987). Shamsudin (1992) reported that prymnesiophyte, Isorchrysis galbana contained considerable amounts of 14:0, 16:0 18:1, 18:4w3 and 226w3.…”

Microplanktonic red tide blooms (dominated by dinoflagellates) were observed in brackish water fish ponds of Terengganu between March 1992 to January 1993. The first short-lived bloom (2-3 days) occurred in October 1992 while the second long-lived bloom (6-7 days) occurred in January 1993. The dominant dinoflagellate species comprised of Peridinium quinquecorne (> 90% total cell count) with considerable proportion of Protoperidinium excentricum. Ciliophora consisting of Tintinopsis sp. and Favella sp. were also present during the bloom period. The total ash, chlorophyll, phaeopigment, lipid and fatty acid content of the microplankton were studied. Considerable amounts (6-11% of the total fatty acid) of the polyunsaturated fatty acid 18:3w3 (linolenic acid) were present in the microplankton. However, high amounts of 20:5w3 (eicosapentanoic acid) and 22:6w3 (docosahexaenoic acid) were present with variable but usually high amounts of 22:4w6 and 22:5w6 acids. The latter microplankton bloom contained higher amounts of 20:5w3 and 22:6w3 acids than the earlier bloom. Lipid content were three to five times higher than chlorophyll a. There was an increase with successive day after bloom outbreak in the relative proportion of total C18, C20, and C22 fatty acid components. The algae microplankton contained the w3-polyunsaturated fatty acids (PUFAs) probably needed for the growth and survival rate of grazing pond animals.
