| 總結: | Methanol-utilizing yeasts were screened for methyl formate- producing activity. Eleven strains
out of twenty strains of yeasts tested were found to have the activity. Pichia methanolica
showed the highest activity, followed by Candida sp. N-16, Candida sp. 1 -B, Pichia pinus, and
Candida sp. 25-A, respectively. Methyl formate was found to accumulate in the cultural media
of those strains during the course of the their growth in methanol- containing media. Along
with the methyl formate-producing activity it wasfoundthat resting cells also had a hydrolyzing
|activity against methyl formate. Cultivation and reaction conditions were optimized with
respect to methyl formate production. The methyl formate-producing activity was strongly
induced by methanol but weakly induced by glycerol. On the other hand, the methyl
formate-producing activity was not induced by ethanol and glucose. However, methyl formate-
hydrolyzing activity was induced by methanol, glycerol, glucose, and ethanol although with
different intensities.
Key words: methanol yeast - methyl formate |
