This study was carried out to determine the storage, cryotolerance, heat and drying resistance when the L. acidophilus growing at optimal temperature was changed growth temperature and to apply it to probiotics production so as to help intensify the viability of lactic acid bacteria in the products. L. acidophilus CT 01 was changed temperature at 22℃ and 28℃ after incubated at 37℃ for 18hours. The viable cell number increased to 4.9×108 and 5.0×108 cfu/mL, respectively in the changed temperature groups, but decreased in the control, rapidly down to 7.4×105 cfu/mL in 36 hours. L. acidophilus CT 01 was stored at 4℃ for 12 days after changed temperature at 22℃ and 28℃ for 48hours, changed temperature groups had a survival rate of 112% and 94.43%, higher than that of control (p<0.05). When stored at room temperature, survival rate in the control was 10.88%, very low, but changed temperature groups had very high survival rate, 74.43% and 85.62% (p<0.05). The cryotolerance of L. acidophilus CT 01 appeared higher than changed temperature groups was observed at 37℃ for 66hours. L. acidophilus CT 01 was heat treated at 60℃ for 15 minutes and 30 minutes to examine heat resistance after changed temperature, the heat resistance of L. acidophilus CT 01 appeared higher than control was observed changed temperature groups. L. acidophilus CT 01 was inoculated by 30% to the carrier after changed temperature, and dried at 50℃ for 12 hours. The highest survival rate of L. acidophilus CT 01 was observed changed temperature groups.

목재 건조의 용이성 및 품질확보, 2차 보존처리를 위한 기초자료 확보를 위해 초고주파를 이용한 캐나다산 직수입 미송의 가열 건조 특성은 다음과 같다. 초고주파 조사 후 목재 내부 온도변화 곡선을 분석한 결과 원주목은 3kW 30분 및 120분 가열 할 경우, 판목은 4kW 3분 및 9분 가열 시 안정적인 열분포와 소비 열량, 표면 함수분포 확보가 가능한 것으로 나타났다. 특히 초고주파 가열에 따른 표면 함수분포는 매우 균일한 Leveling이 이루어진 것으로 나타났으며, 함수 감소율도 중량대비 30% 이상인 것으로 나타나 건조효율이 우수한 것으로 나타났다. 또한 소비 열량 분석 결과에 따라 2차 액상 보존처리를 위한 침지 시 대량의 보존처리제 침투가 가능할 것으로 사료되므로, 초고주파 가열 목재는 빠른 함수감소 및 건조 특성과 많은 열량의 소비가 가능하여 산업재로의 사용 및 2차 응용제품 개발에 우수한 특성이 있는 것으로 사료된다.
