 note = {The artificial culture media for the uni-cellular red algae, Porphyridium cruentum, were studied. The culture was carried out under following conditions: temperature of 18-22°C, illumination period of 9 hours per day by fluorescent lamps and aeration of 200-300 cc per minutes. The suitable concentrations in the media of the major constituents such as NaCl, KCl, MgSO_4 and CaCl_2 were examined. Sodium chloride in very wide concentrations gave a normal growth of the algae. The concentration of potassium chloride was closely related with that of sodium chloride and the favorable ratio of the two seemed to lie around 40:1. Magnesium sulfate was indispensable for the growth of the algae, although the requirement was small. Under the purity of used chemicals, the absence of calcium chloride allowed the growth of the algae. From the above, the author prepared an artificial medium for the culture of Porphyridium cruentum. The formula is presented in Table 11. The extra-cellular mucus produced by the algae was calculated about 26-30% of total organic materials. In the mass culture performed in the tube method and the 30 liter tank method, the yield of the alga was about 260 mg per liter per day in the former and 74.7 or 58.2 mg per m^{2} per day in the latter., 単細胞紅藻チノリモを人工的に培養するために必要な諸条件について検討し,培養を容易且つ安定ならしめるための要因を明らかにした。即ち適温20±2°C,桃色螢光灯の連続照射或は白色螢光灯の9時間照射,通気によるガス補給及び攪拌,等の環境条件が要求される。培養液はかなり広い適応範囲を持っているが,もっとも影響の大きいのはNaClとKClの濃度及び比率で,Mg,Ca等の濃度は直接にはあまり大きな影響を示さない。このような結果を参考にしてチノリモ用の培養液の処方を作った。チノリモの分泌する粘質は藻体の生長と平行して増加し,その分泌量は有機物量として計算した場合生産された全有機物量の30~26%を占めている。大量培養に関する簡単な実験では,Tube methodでは8.8g/m^{3}/day,Tank methodでは74.7mg/m^{2}-day~58.2mg/m^{2}-dayであった。},
