Microalgal cultivation in a solution recovered from the low-temperature catalytic gasification of the microalga

Microalgal cultivation in a solution recovered from the low-temperature cat alytic gasification of the microalga itself was studied. The growth of Chlo rella vulgaris in 75-300-fold diluted recovered solution containing phospha te, magnesium ions and micro-elements was comparable to that in the standar d culture medium. It was suggested that C, vulgaris could use ammonium in t he recovered solution as its nitrogen source and at the same time could pro vide a source of biomass which was recycled via gasification.
