Abstract
|
|
|
|
The effects of tunicamycin (TM) on the growth and α-amylase productivity of B. amyleliucfaciens K were studied. The minimal growth inhibitory concentration was 0.25㎍/㎖ and its α-amylase was stable up to 50℃. When the saking culture with 1㎍/㎖ of Tunicamycin oaused the change of cell shape from form rod to irregular circular form and the mycelium lysis. the grow th of His-. TM mutant obtained by treatment of TM and ultraviolet ray was similar to that of the parent strain, but the productivity of α-amylase, protease, and RXase was lower than that of the parent.
