Week 9 (7/29~8/4)
Sunday
SRB
* Sub clone DsrI-BamHI-DsrII gene from pSB1C3 into Ptrc-kan plasmid
* Ptrc-kan plasmid cut with EcoRI, XbaI
* MF-pSB1C3 -DsrI-BamHI-DsrII gene Cut with MfeI, SpeI
*(smart trick: MfeI and EcoRI form scar, SbfI and SpeI form scar, to prevent endogenous EcoRI and PstI site)
- SQR
* Synechococcus sp. PCC7002 was cultured in the medium A2, rotary shaker and initial cell concentration are the same as the last experiment. DCMU is diluted with A2 medium into different concentration, and 10 mM of sodium sulfide is added to the experimental group. The measurement method and frequency of cell growth has been described previously.

Sunday
SQR
* The effect of sodium sulfide on Synechococcus SP. PCC 7942 growth rate
* In this experiment, we aimed to examine whether the SQR Synechococcus SP. PCC 7942 expressed is functional. Synechococcus SP. PCC 7942 with SQR and wild type was cultivated in BG-11 medium (Allen M.M. 1968) on the same rotary shaker described in the first experiment. Initial cell concentration is fixed to an OD730 of 0.1 in the medium. 2.5mM of sodium sulfide is added into the experimental group, and DCMU is diluted from 1μM to 0.5μM.
Monday
NirN-RBS-NirS-RBS-NapABC
* Sub clone NirN-RBS-NirS gene from pSB1C3 and NapABC gene from MS-pSB1C3 into Ptrc-kan plasmid
* Ptrc-kan plasmid cut with EcoRI, XbaI
* MF-pSB1C3 -DsrI-BamHI-DsrII gene Cut with MfeI, SpeI
*(smart trick: MfeI and EcoRI form scar, SbfI and SpeI form scar, to prevent endogenous EcoRI and PstI site)
- SQR
* SQR part experiment
* DCMU concentration and cell growth
From the last experiment, we found it necessary to perform another independent experiment to find the optimal DCMU concentration of Synechococcus SP. PCC 7942. In addition, the initial cell concentration was adjusted to an OD730 of 0.2 in BG-11 medium. DCMU is diluted from 1μM to 0.1251μM. Except of cell concentration, all condition remained the same for both sqr and wild type strain of Synechococcus SP. PCC 7942.
