| Outline of Final Research Achievements |
New thermophilic L-lactic acid producing Bacillus sp. MC-07 strain with starch utilization was isolated and identified. This strain was different from Bacillus thermoamylovorans LMG 18084T at species level regardless of 99.2% similarity of 16S rRNA gene sequence. This strain showed higher lactic acid production by pH-swing control every 12 h using gelatinized starch with heat treatment than LMG 18084T strain. Furthermore, we could establish a direct lactic acid production process without saccharification process from non-gelatinized starch.
