Article Synopsis
- Thermotolerant microorganisms, like Acetobacter pasteurianus, are essential for high-temperature fermentation but typically struggle in nutrient-poor media like rice moromi.
- Researchers adapted A. pasteurianus K-1034 through experimental evolution in a "pseudo" rice moromi culture, leading to strains able to thrive in low-nutrient conditions at temperatures up to 40°C.
- The adapted strains demonstrated comparable acetic acid production efficiency to previously adapted strains in practical settings, indicating their potential for effective vinegar production in high-temperature environments.
The gene sequences encoding disaggregatase (Dag), the enzyme responsible for dispersion of cell aggregates of Methanosarcina mazei to single cells, were determined for three strains of M. mazei (S-6(T), LYC and TMA). The dag genes of the three strains were 3234 bp in length and had almost the same sequences with 97% amino acid sequence identities.
