January


Our junior and senior students were attracted by the recruiting announcement for the iGEM 2015 in our university. After several interviews and competitive selections, our team was basically created.


February


Our team was growing. We communicated with previous iGEMers in our school to get more insights into iGEM. Meanwhile, we started to watch successful iGEM cases of previous years.


March


We wandered among wikis and gradually realized what the basic factors are for a good project. Brainstorms and weekly meet-ups promoted us to discover the quintessence of iGEM.


April


We urged ourselves to get deeper insights into those previous cases to catch their inspiration. After meet-ups with teammates and our instructors, a draft idea of a yogurt guarder came to our mind. To make sure our project was worth proceeding, we did a survey to find out how much attention people would pay to the quality of yogurt. Fortunately, we got the expected results, although we knew we still had a long way to go.
May

We primarily designed the basic structure of our project. Then we read numerous papers to make an integrated protocol of our lab work.Besides, we visited a dairy factory to learn the microbiological detection methods used in practical production of yogurt. We discovered that our method to be developed should have advantages over the traditional methods, especially in portability. 
In addition, it was essential for us to adapt to the wet lab work. We started with laboratory safety training. With the instruction of our instructors and previous iGEMers, we learned a lot of techniques in molecular biology.
June
With efforts, our wet lab work went smoothly.
July
This month, we organized public activity to popularize the knowledge of yogurt production and its quality inspection, and remind people to store yogurt properly. 

In addition, we did a survey to confirm the key factors which will attract customers’ attention if our yogurt guarder is developed into a real product. 
August
On 13th-15th, we attended the summit of Central China iGEM Consortium held by Peking University. We shared our experience with other teams and really learned a lot from other teams. Here we want to express our sincere thanks to them! 
Meanwhile, our lab works still proceeded. We encountered difficulty in the electrotransformation of bacteria, which delayed our project but was eventually resolved after multiple attempts.

September
Time flies. We seized the time to make everything done and put great efforts to the wiki building and preparation for the Giant Jamboree.

 Isolation of genomic DNA from bacteria             The genomic DNA of Salmonella enterica subsp. enterica serovar Typhimurium str. LT2 and Lactobacillus delbrueckii subsp. Bulgaricus str. Lb14 were isolated using the TIANamp Bacteria DNA Kit (see protocol). The concentration of genomic DNA was measured with a NanoDrop spectrophotometer.         

Strain identification

We applied 16S ribosomal DNA identification to identify the strain of Salmonella and Lactobacillus bought from a biotech company. Universal primers were designed according to the conserved sequences.

 The sequence was consist with that of Salmonella enterica subsp. enterica serovar Typhimurium str. LT2.

The sequence was almost consist with that of Lactobacillus delbrueckii subsp. Bulgaricus str. Lb14. The differences were caused by subculturing perhaps.

Miniprep (pNZ8148–LsrB, pNZ8148–LsrR, pNZ8148–LsrK) with TIANprep Mini Plasmid Kit

1.Preparation of competent cells 

100 μl bacterial culture were inoculated into 50ml of MRS and incubated at 37°C. After overnight growth, a culture at the beginning of the stationary phase was harvested by centrifugation. The bacteria were washed three times with cold electroporation buffer (PB).The cells were then resuspended in PB to an OD600 of about 50.

2.Electrotransfection 

100  μl of the cell suspension was mixed with 10 μl plasmid DNA(pNZ8148–LsrB, pNZ8148–LsrR, pNZ8148–LsrK). The sample was subjected to a 2.4kV, 200Ω, 25μF electric pulse in a 0.2cm cuvette.

3.Recovery of transformants

950 μl SMRS was immediately added, and the cells were incubated for 2 h at 37°C before they were plated on MRS supplemented with the appropriate antibiotic. The plates were incubated at 37°C for 2 to 3 days under anaerobic conditions.

4.Clone identify

We repeated this transformation process for several times. Unfortunatelly, not a single colony was grown the plate.

Then we changed the parameters of electric pulse and tried several recovery medium, but we just got some unsatisfactory results.

Finally, we realized it was the concentration of the plasmids which led to the low efficiency in transformation. We then did plasmid Maxiprep (see protocol) and concentration, and obtained plasmids in a concentraion of about 3000ng/μL. We also added 100μL denatured salmon sperm DNA to the cuvette before electroporation. This time, we eventually gained positive colonies.
