| Outline of Final Research Achievements |
We found sub-terminal oxidation pathways of n-alkanes in micro-alga Prototheca sp. by screening microorganisms based on degradation of n-alkanes. We tried purification of a secondary alcohol dehydrogenase (SADH) involved in oxidation of a secondary alcohol to the corresponding ketone from P. zopfii JCM9400, and cloning of the encoding gene. Expression of the gene in Escherichia coli revealed that the SADH converted 2-dodecanol to 2-dodecanone. Determination of draft genome sequences in P. zopfii JCM9400 disclosed high GC contents, more than 60% of GC contents in open reading frames, and more than 70% of GC contents in non-coding regions. We succeeded the development of transformation system of P. zopfii JCM9400 by means of particle bombardment.
