Abstract
In the present study, comparison between Spirulina platensis and
Chlorella vulgaris in protein, carbohydrate content, growth and
pigment production then was used, the alga with highly protein content
in fish diet.
Spirulina platensis and Chlorella vulgaris was grown in batch
cultures using Erlenmyer flasks containing Zarrouk’s medium and
Kuhl’s medium, respectively. The flasks were inoculated for 12 days to
grow Spirulina and 9 days to grow Chlorella, growing pre-culture and
incubated in illuminated incubator. At the end of incubation period, the
growth, protein, chlorophyll a, carotenoid, chlorophyll b and
carbohydrate were quantified.
The results of the present study are summarized as follows:-
Comparison between Spirulina platensis and Chlorella vulgaris in
growth parameter and biochemical composition.
Chlorella vulgaris is higher than Spirulina platensis in biomass
where the highest dry weight was 0.16 g1100 ml at the 12& of
incubation and 0.2 dl00 ml of algal suspension at 9& day of incubation
to Spirulina and Chlorella respectively. While Spirulina is higher than
Chlorella in protein content where Spirulina has 64.7% of the dry
weight but Chlorella has 58% of the dry weight, The maximum
chlorophyll a and carotenoids of Spirulina (11.9 4.6 mdg,
respectively) was at the 12& day, but maximum chlorophyll a,
chlorophyll b and carotenoids in Chlorella were 6.4, 5.29, and 3.19.
