Cultivarea algei nostoc flagelliforme (berk et. curt) elenk. după metoda semicontinuă [Articol]

Abstract

The semicontinuous method for cultivation the alga Nostoc flagelliforme leads to a higher quantity of biomass in a short period of time. The high algal productivity is obtained at elimination and substitution of 25% of the nutritive medium Z-8 (12,44 g/l) and elimination and substitution of 50% of medium Drew (5,78 g/l). The pH of the nutritive media for cultivation the alga Nostoc flagelliforme by semicontinuous method have increasing trends followed by decreasing and does not differ substantially depending on the concentrations of elimination and substitution of nutritive medium.
