ジアミン化合物の製造方法には、先述の実施形態にかかる組換え微生物を培養する培養工程が含まれる。例えば、組換え微生物を、炭素源および窒素源を含有する培地で培養することによって、菌体を含む培養液が得られる。
本工程は、ジアミン化合物の前駆体を組換え微生物に接触させる工程であり、ジアミン化合物前駆体から目的のジアミン化合物を生成する。ジアミンの前駆体との接触は、例えば、先述のように前記培養工程において行ってもよいし、あるいは、培養工程の後に行ってもよい。本反応工程を、培養工程の後に行う場合、培養工程で得られた培養液および/または菌体を、ジアミン化合物の前駆体を含有する水溶液と接触させてジアミン化合物を含む反応液を得る。このように前駆体と接触させることで、ジアミン化合物を反応液中に生成蓄積させる。
