Description A laboratory scale continuous and semi-continuous system for culture of the
marine diatom Chaetoceros sp. was devised. Using 2.5 times the normal nutrient
concentration and limited supply of Co2, the culture density could be
increased from an average 1.5 million cells / ml concentration in traditional
batch culture systems to 13.7 million cells/ml in continuous system. Besides the
increased biomass production, the duration of culture was enhanced to thirty
days without crashing. The semi-continuous system was up-scaled to 60 1 capacity
with an internal illumination system to yield 528 litres of average 3.2
million cells/ml within 36 days. The velocity of cell growth during the logarithmic
phase in doublings/day ranged from 0.21 in control (batch culture) to 2.51
in the semi-continuous system. Furthermore, the cost of production, even with
additional inputs, are comparable or even less than the traditional batch cultures.
The economic efficiency was highest in continuous systems as compared
to semi-continuous systems (Rs. 0.03 and 0.017/billion cells as against Rs. 0.082
and 0.037/billion cells).
