Abstract:
An experiment was accomplished on the rooftop of agricultural faculty of Sher-eBangla
Agricultural University during the period from July to September, 2018 to
screen some Photobioreactors for finding out more economically convenient and
easily available one for spirulina production in Bangladesh. Four types of
photobioreactors viz. Rectangular shaped 5L photobioreactor (PBR
1
), Cuboidal shaped
3L Photobioreactor (PBR
2
), Cylindrical shaped 15L Photobioreactor(PBR
3
),
Rectangular shaped 15L Photobioreactor (PBR
4
) ware used in this experiment
arranged in a Completely Randomized Design (CRD) with three replications. Fifteen
days of production was carried out in the selected photobioreactors to fully determine
the performance of the PBR
s
where culture condition were kept the same and data on
different growth and yield parameters were taken throughout the experiment to which
all the PBR
S
showed significant variations. Among photobioreactors, minimum
doubling time (3.41 days), maximum productivity (0.90 gL
-1
day
-1
) and maximum
marketable yield (3.34 Kg/1000L) were found in PBR
4
while maximum doubling time
(10.63 days) and minimum productivity (0.40 gL
-1
day
-1
) and minimum marketable
yield (1.64 Kg/1000L) in PBR
2
. These findings may be a source of valuable
information for adopting Rectangular shaped 15L Photobioreactor (PBR
4
) as a
promising photobioreactor for spirulina cultivation in Bangladesh.
