Abstract |
In the present study, a new strain, Bacillus cereus ZY12, producing
phospholipase D (PLD) was identified. The expression
of PLD in this strain was found to be induced by its substrate,
phosphatidylcholine (PC), and completely silenced by
other carbon sources, such as glucose, fructose, and maltose,
which are generally used in microbial growth cultures, thus
presenting a unique expression pattern different from other
PLD-producing microorganisms. This study is the first to
report on the ability of B. cereus to produce PLD, and successfully
clone its PLD-coding gene and identify its function,
extending the knowledge on PLD distribution and evolution
in microorganisms. |
