Abstract

Autotrophic cultures of the marine microalgae Chlorella minutissima were performed at 13 000 lux continuous illumination in 11 chambers fertilised with 0.25 g l - 1 F2 medium and different doses of methanol. This was administered in two ways during two parallel experimental series of 10 days: 0.05, 0.1, 0.5, 1.0 and 5.0% methanol (v/v) in one unique dose at the beginning of the culture and 110 of these (i.e. 0.005, 0.01, 0.05, 0.1 and 0.5% methanol (v/v)) in daily doses for the 10-day culture period. Low concentrations of methanol induced a faster increase of cell density and dry weight than control, while high concentrations induced symptoms of toxicity. The higher cell densities and quicker growth were observed in the experiments with daily administration of 0.005 and 0.1% (v/v) methanol, while those with one dose presented an initial boosted growth but a final cell density lower than control. The role of methanol as alternative carbon source for microalgae, as well as its possible impact on the quality of biomass production and on the environment, are discussed. © 1999 Elsevier B.V.
