Different carbon sources had a modest influence, while nutrient limitations significantly altered the fatty acid composition. Lower oxygen supplies reduced unsaturation and increased chain length. Moreover, a neutral pH favored longer chains, while a basic pH increased unsaturation. The addition of citric acid significantly boosted palmitic acid content by 36 %.
