Importance of Oxygen Availability in Two Plant-Based Bioprocesses: Hairy Root Cultivation and Malting. (Hapen saatavuuden merkitys kahdessa kasvipohjaisessa bioproseeissa: juuriviljelmissae ja mallastuksessa).

摘要

The main aim of this work was to examine the role of oxygen availability in two model processes: the cultivation of Agrobacterium rhizogenes-induced hairy roots of the medicinal plant Egyptian henbane (Hyoscyamus muticus), and barley (Hordeum vulgare) malting. This was accomplished by transferring the vhb gene encoding bacterial haemoglobin (VHb) from Vitreoscilla to H. muticus and to barley with the specific goals of improving the growth and alkaloid production of H. muticus hairy roots and the germination rate of barley.
