Resumen:
Microalgae have great potential as alternative productive platforms for sustainableproduction of bioenergy, food, feed and other commodities. Process optimization torealize the claimed potential often comprises strains selection and improvement and alsodeveloping of more efficient cultivation, harvesting and downstream processingtechnology. In this work we show that inoculation with the bacterium Rhizobium strain10II resulted in increments of up to 30% in chlorophyll, biomass and lipids accumulationof the oleaginous microalgae Ankistrodesmus sp. strain SP2-15. Inoculated cultures havereached a high lipid productivity of up to 112 mg . L-1 . d-1 after optimization. Theresulting biomass presented significant levels of Ù3 fatty acids including stearidonic acid,suggesting potential as an alternative land-based source of essential fatty acids.
