| Abstract |
The temporal variation of 2-Methylisoborneol (2-MIB) and Geosmin (GSM) production in two filamentous cyanobacteria species, Pseudanabaena galeata and Phormidium ambiguum, was tested under three temperature regimes (20°C, 30°C, and 40°C). The 20°C is considered the ideal cultural temperature for both species. The 2-MIB, GSM, cellular H2O2, pigmentation, and total protein were quantified every other day for a 10-day period. Both species showed temporal variation in the measured parameters, but the variations were distinct between the two species. P. galeata showed significant changes in odor compound production at 40°C compared with 20°C and 30°C, recording a maximum 2.4-fold increase of 2-MIB and an 8.2-fold increase of GSM. P. ambiguum showed significant changes at 30°C and 40°C. 2-MIB of P. ambiguum increased a maximum of 13-fold at 30°C and 19-fold at 40°C, and GSM increased by 17-fold at 30°C and 4.6-fold at 40°C. The total chlorophyll content, H2O2 contents, and protein contents were also recorded with significant changes. No significant relationships were observed between odor compounds and other parameters. |
