Microalgae have great potential as alternative productive platforms for sustainable production of bioenergy, food, feed and other commodities. Process optimization to realize the claimed potential often comprises strains selection and improvement and also developing of more efficient cultivation, harvesting and downstream processing technology. In this work we show that inoculation with the bacterium Rhizobium strain 10II resulted in increments of up to 30% in chlorophyll, biomass and lipids accumulation of the oleaginous microalgae Ankistrodesmus sp. strain SP2-15. Inoculated cultures have reached a high lipid productivity of up to 112 mg L(-1) d(-1) after optimization. The resulting biomass presented significant levels of Ω3 fatty acids including stearidonic acid, suggesting potential as an alternative land-based source of essential fatty acids.
微藻作为替代生产平台，具有可持续生产生物能源、食品、饲料和其他商品的巨大潜力。为了实现所宣称的潜力，通常需要进行工艺优化，包括菌株选择和改良，以及开发更有效的培养、收获和下游加工技术。在这项工作中，我们表明，用细菌 Rhizobium 菌株 10II 接种可以使产油微藻 Ankistrodesmus sp. 菌株 SP2-15 的叶绿素、生物量和脂质积累增加高达 30%。经过优化，接种培养物的脂质生产力达到了高达 112 mg L(-1) d(-1)。所得生物质含有大量的ω3 脂肪酸，包括硬脂酸，表明其可能成为陆地来源必需脂肪酸的替代来源。
