Abstract:
The growth predominance and culturing potential of transgenic Synechococcus sp.PCC 7002 with mouse metallothionein-Igene are characterized and expatiated by room temperature absorption spectra,photosynthetic oxygen evolution rate,growth kinetic parameters.The results show that the spectral absorption,maximum net photosynthetic rate and saturated light intensity of transgenic Synechococcus sp.PCC 7002 are higher than wild strain,whereas its the respiration rate and compensating light intensity are lower than wild strain.The transgenic cells exhibit a higher growth rate,and the maximum cell concentration is 1.74 times higher than wild ones when cultured in shaking flask.The air lift photobioreactor is suitable for bringing its growth potential into play.
