PRODUCTIVITY AND PIGMENT COMPLEX OF BLUE-GREEN ALGA SPIRULINA PLATENSIS AFTER PARTIAL SUBSTITUTION OF SODIUM BICARBONATE WITH SODIUM HYDROXIDE IN CULTURE MEDIUM
Abstract
It has been shown that the partial substitution of NaHCO3 with NaOH in the culture medium of Spirulina platensis does not lead to a change in productivity of the algal culture. Substitution of 25 to 50 % of sodium bicarbonate with sodium hydroxide makes it possible to obtain biomass with a similar content of key pigments as compared to the control (standard Zarrouk medium) while allowing for a significant reduction in the cost of reagents for the preparation of culture medium.
