Abstract
The present study was initiated to identify the best
medium for culture of Chaetoceros calcitrans that
could provide better protein and lipid content while
supporting good growth of the algae. The media
selected were Walne’s, Miquel’s, Chu and f/2 media.
The algae cultured in Walne’s, Miquel’s and f/2
media showed significantly higher content of lipid
(P<0.05) in the late exponential phase. Protein
content was the highest in Walne’s medium (32.53
± 0.28% dry weight) as compared to other media
tested. Maximum cell density was recorded in f/2
medium. Miquel’s medium gave the maximum
carbohydrate content (16.92 ± 1.54% dry weight). It
was observed that media could certainly influence
the biochemical composition of microalgae and
therefore selection of media should be based on the
larval requirement of the target species. Results
obtained in the present study revealed that
microalgae cultured in Walne’s medium gave high
values of protein and lipid content. Although cell
count was the highest in f/2 medium, Walne’s
medium provided the best nutritional quality of
algae.
