Abstract:
A mutant capable of producing 1,4-butanediol and a method of preparing 1,4-butanediol using the same are provided. The mutant microorganism is prepared by introducing and amplifying genes encoding enzymes converting succinate into 4-hydroxybutyrate and 4-hydroxybutyrate into 1,4-butanediol in a microorganism capable of producing succinate. The method includes culturing the mutant in a medium containing carbohydrate and obtaining 1,4-butanediol from the culture. Thus, 1,4-butanediol, which is essential in chemical industry, can be prepared in a biological process.
Abstract:
Disclosed is a method of a handover in a wireless communication system. The method includes transmitting a handover request message to the service BS, and receiving a handover command message from the service BS in response to the handover request message. Multi-carriers are assigned to a terminal in advance right before a handover, and all or some of the multi-carriers are activated right after the handover. Therefore, multi-carrier are effectively utilized.
