Abstract

Nitrite at 2 mm did not affect the growth of Botryococcus brauniiand served as the sole nitrogen source giving a minimum biomass doubling time of 4.2 d, which was equal to that of the culture using 4 mm nitrate as nitrogen source. With nitrite at 4 mm, after a lag phase of about 10 d, the alga grew quickly, reaching 1.1 g l−1 at the end. Respective nitrite removals were 100% and 99.7%. There were few differences in the hydrocarbons produced using different nitrogen sources.
