Schizochytrium sp. AB‐610 accumulates relatively higher amount of DHA‐rich lipid in the cells, and it was found that DHA yield was closely related to the cell morphology and pH value during fermentation period. DHA production from Schizochytrium sp. AB‐610 in fed‐batch fermentation was investigated and four growth stages were clarified as lag stage, balanced growth stage, lipid accumulation stage, and lipid turnover stage, based on the morphologic observation and key parameters changes. Then a simple strategy of two‐stage pH control was developed, in which pH 7.0 was kept until 12 h after the end of balanced growth stage, and then shifted to 5.0 for the rest period in fermentation. A maximal DHA production of 11.44g/L was achieved. This approach has advantage of easy scaling up for industrial DHA fermentation from Schizochytrium sp. cells.

“…Thraustochytnds are a group of non-photosynthetic marine fungoid protoctists, characterized by the presence of an ectoplasmic net and a cell wall composed of non-cellulosic, sulfrylated scales (Darley et al 1973). Thraustochytrids are classified in the phylum Heterokonta within the kingdom Chromista, and no longer regarded as a lower fungus.…”

Abundance, cellular contents of carbon and nitrogen, and C/N ratio of planktonic thraustochytrids in the Seto Inland Sea and the coastal Hyuga-nada, Japan, were determined. Thraustochytrid cells were stained with acrflavine and counted dlrectly by epifluorescence rnicroscopy.Thraustochytrids were found in the water column at a density of 2.5 X 103 to 4.5 X 104 cells I-', with an overall average of 1.6 X 104 cells 1-l. In order to estimate the impact of thraustochytrid biomass on the coastal plankton community, cellular carbon and nitrogen contents of a cultured thraustochytrid were determned. The carbon and nitrogen for 10 pm cell contents were estimated to be 1.65 X 10-4 pg C cell-' and 1.58 X 1W5 pg N cell-', respectively. The cellular C/N ratio of 10.4 was higher than that known for pelagic bacteria. The estimated population biomass of thraustochytrids varied from 0.41 to 7.44 pg C I-', with an overall average of 2.60 pg C 1-'; and 0.039 to 0.71 pg N I-', with an overall average of 0.23 pg N I-'. The thraustochytrid carbon biomass corresponded to about 3.4 to 29% of total planktonic decomposers [bacteria and thraustochytrids). It is suggested that the contribution of thraustochytrids to the microbial food chain and carbon cycling through organic degradation and production may not be negligible.
