METHOD OF CULTURING A MFCROORGANISM A METHOD OF CULTURING A MICROORGANISM CAPABLE OF PRODUCING AT LEAST ANY ONE OF A HIGHLY UNSATURATED FATTY ACID OR A COMPOUND CONTAINING A HIGHLY 6 UNSATURATED FATTY ACID AS A CONSTITUENT FATT Y ACID IN A CULTURE MEDIUM CONTAINING AT LEAST A CARBON SOURCE AND A NITROGEN SOURCE, USING AN AORATION-AGITATION CULTURE DEVICE CAPABLE OF ADJUSTING AND CONTROLLING AN AGITATION POWER AND AN AERATION AMOUNT. THE METHOD COMPRISES THE STEPS OF PERFORMING MECHANICAL AGITATION FOR A PREDETERMINED TIME AFFTER START OF 10 CULTURE, WHERE THE AGITATION POWER PER UNIT LIQUID AMOUNT IS 269 MM) OR LOSS, AND AFTER THE PREDETERMINED TIME HAS PASSED, ADJUSTING AND CONTROLLING AT LEAST ANY ONE OF THE MAXIMUM AERATION AMOUNT AND A MAXIMUM POWER REQUIRED FOR AGITATION TO A RANGE WHICH SATISFIES THAT KIA (=(PN)0.95VI3G.67) IS 59 OR MORE, AN AIR FLOW RATE PARAMETER V80.67 IS 0.075 OR MORE, AND A REQUIRED 15 AGITATION POWER PARAMETER (P/V)').'3R, IS 203 OR MORE, WHERE P REPRESENTS POWER REQUIRED FOR AGITATION (W), V REPRESENTS A LIQUID AMOUNT (RN3), AND VS REPRESENTS AN AIR FLOW RATE (M/130C). |
