Method for increasing content of arachidonic acid in porphyridium

The invention discloses a method for increasing the content of arachidonic acid in porphyridium and belongs to the field of aquaculture. Traditionally, porphyridium is cultured by an Allen culture medium in an open runway type large pond, so the growth is slow, the yield is low, pollution is easy to cause, the cost is high, basic investment is high, the content of arachidonic acid is low and the product quality is poor. According to the method disclosed by the invention, an illumination incubator is adopted for culture; in the later period of the culture, the illumination intensity and the illumination temperature are increased to force the porphyridium to accumulate arachidonic acid; sodium nitrate, ammonium chloride, ammonium bicarbonate, nicotinic acid alpha-naphthylacetic acid, magnesium sulfate, Na2EDTA and the like are replenished, and nutritional salts are replenished in batches in the later period of the culture, so that the nutrition requirements of the porphyridium are satisfied, the toxicity caused to porphyridium cells because of over-high concentration of the nutritional salts in the early stage due to one-time addition of the nutritional salts is overcome, the growth speed and yield of the porphyridium are greatly increased, and the content of arachidonic acid in the porphyridium is increased by 120%.
