[Determination of chromosome of Gluconobacter oxydans SCB329]

After the pure culture of Gluconobacter oxydans SCB329 was researched, its growth curve was measured and its logarithmic phase was determined as between 4-24 h. After the microorganisms were havested in its logarithmic phase, The intact chromosome was prepared by agarose-embedded method. Then the genome of SCB329 was analyzed by Pulsed-field Gel Electrophoresis. The result indicated that there are one chromosome and one great plasmid. The length of intact chromosome of SCB329 has been estimated to be approximately between 2.2 Mb and 3.5 Mb.
