5. 3 Euglena การทรานสฟอร์ม (Co-culture)
Euglena was cultured in a KH medium (pH of 6.8) for 4
to 5 days and, after cell counting, suspended in an IM liquid
medium to 5.0x106 cells/ml.
[0060]
The อะโกรแบคทีเรียม ทรานสฟอร์แมนต์ was subjected to
preculture in an อาหาร LB. The resulting ทรานสฟอร์แมนต์ was
inoculated in an IM medium (pH of 5.3) (Tables 2 to 4) and
cultured for about 10 to 15 hours. The cultured bacteria cells
were collected by centrifugation (7,700xg, 20°C, 1 min) and
suspended in the IM liquid medium so that 0D660 was 0.6.
1 ml of the Euglena suspended in the liquid medium and
1 ml of the อะโกรแบคทีเรียม ทรานสฟอร์แมนต์ suspended in the liquid
medium were mixed (a total of 2 ml of culture solution), and
acetosyringone was added at a final concentration of 100 ILE,
followed by co-culturing for 48 hours while gently stirring with
a rotator (2.5x106 cells/ml, OD660 = 0.3) . After the completion of
the culture, 200 111 of the culture solution (0.5x106 cells) or 200
[11 of a 10-fold dilution of the culture solution (0.50x106 cells)
was cultured in a KH selective plate medium (ซีโอซิน 25 lg/ml,
ซีโฟแทกซีม 100 [1g/ml)
