peels are usually disposed of or treated as fertilizer. The peel, however,
contains rich nutrients that can be used as a medium for growing microbes.
Conventional culture medium is widely used for growing microbes, but the cost
is very high and it is not suitable to produce cyanobacterium-based biofuel,
biomass, and in other applications. Therefore, this study explores the
potential for using fruit peels as a culture medium for Anabaena cylindrica. The fruit peels were dried, homogenized, and
filtered to make different concentrations of fruit peel media (5%, 10% and
20%). For comparison, BG-11 medium acted as a positive control whereas
deionized water serves as a negative control in this experiment. Growth of A. cylindrica in different types of
media was analyzed after cell counting using a hemacytometer and biomass
measuring. The cyanobacterial growth
rate and biomass production were recorded in different types of fruit peel
media with different concentrations. A.
cylindrica have greater biomass yield when growing in 20% papaya peel
medium and a higher growth rate when growing in 10% pineapple peel media
compared to that growing in the BG-11 medium. In other words, the fruit peel
media have more potential in growing cyanobacteria than conventional medium. |
