Description
従来、不飽和脂肪酸又はその誘導体の製造には、エキノスポラジウム(Echinosporangium)属糸状菌、モルテイエレラ(Mortierella)属糸状菌、ロドコッカス(Rhodococcus)属細菌等の微生物を用いた発酵法が知られている。
しかしながら、この方法においては、濃度0.25M以上のリン酸緩衝液を用いることが必要であった。
ロドコッカス(Rhodococcus)属に属する不飽和脂肪酸生産菌としては、飽和脂肪酸から不飽和脂肪酸を生産する能力を有するものであればよく、例えばロドコッカス・エスピー(Rhodococcus sp.)KSM−B−3M株(FERM BP1531)や、ロドコッカス・エスピー(Rhodococcus sp.)KSM−T645株(FERM P−18182)等が挙げられる。このうち、不飽和脂肪酸又はその誘導体の生産量の点からロドコッカス・エスピーKSM−T645株が特に好ましい。ロドコッカス・エスピーKSM−T645株は、ロドコッカス・エスピーKSM−B−3M株に紫外線を照射して得られた変異株である。
従って、シードとして指数期のものよりも定常期のものを用いた場合に良好に不飽和脂肪酸又はその誘導体が製造できたことは、全く意外なことである。
例えば、Rhodococcus sp. KSM-T645株をMSG 225g、酵母エキス30g、K2HPO4 30g、グルコース 225g、MgSO4・7H2O 7.5g、FeSO4・7H2O 225mg、CuSO4・5H2O 18mg、MnSO4・5H2O 9mg、シリコン系消泡剤(信越化学工業株式会社製)30gをイオン交換水15Lに溶解した培地を入れた30L容ジャーファーメンターに接種し、30℃、350rpm、0.5vvmの条件でシード培養を行った場合には、培養約30時間目より定常期に移行する(図1)。
また、シードの分離は、得られた培養液をそのまま、或いは培養液から菌体を遠心分離等の方法により回収すればよい。
ここで、菌体培養液又は菌体は、反応液に対して0.1〜10%、特に0.5〜5%用いることが好ましく、脂肪酸又はその誘導体は、1〜30%、特に10〜25%であることが好ましい。
実施例1 シード培養における菌体生育度経時変化の測定
Rhodococcus sp. KSM-T645株を、グルタミン酸ナトリウム(以下、MSGと略記)5g、酵母エキス(Deutsche Hefewerke GmbH & Co.oHG製;以下、単に酵母エキスと略記)2g、K2HPO4 2g、グルコース10g、MgSO4・7H2O 0.5g、FeSO4・7H2O 15mg、CuSO4・5H2O 1.2mg、MnSO4・5H2O 0.6mgをイオン交換水1Lに溶解した培地30mLを入れた500mL容ひだ付き三角フラスコに1白金耳接種し、30℃にて1日間、210rpmにて振とう培養を行った。
実施例1で適当な時間に抜き取ったシード培養液0.4mLをそれぞれ、MSG 25g、酵母エキス3g、MgSO4・7H2O 0.5g、FeSO4・7H2O 15mg、CuSO4・5H2O 1.2mg、MnSO4・5H2O 0.6mg、チアミン塩酸塩0.17gを0.35Mのリン酸緩衝液(pH7.0)1Lに溶解した培地 20mL及びパルミチン酸イソプロピルエステル(以下、IPPと略記)4.0mLを入れた500mL容ひだ付き三角フラスコに接種し、26℃にて4日間、210rpmにて振とう培養を行った。
Rhodococcus sp. KSM-T645株を、MSG 15g、酵母エキス2g、K2HPO4 2g、グルコース 15g、MgSO4・7H2O 0.5g、FeSO4・7H2O 15mg、CuSO4・5H2O 1.2mg、MnSO4・5H2O 0.6mgをイオン交換水1Lに溶解した培地30mLを入れた500mL容ひだ付き三角フラスコに1白金耳接種し、30℃にて41.5時間、210rpmにて振とう培養を行いシード培養液を得た。
