Chemical composition of neem and lavender essential oils and their antifungal activity against pathogenic fungi causing ginseng root rot

The aim of this study was to assess in vitro, the antifungal activity and characterize the chemical constituents of the essential oils of Azadirachta indica (neem) and Lavandula angustifolia (lavender).  The essential oils of A. indica and L. angustifolia plants were tested against several isolates of pathogenic fungal genera causing root rot disease of ginseng. Agar plate assay indicated that lavender oil at 10%...

Plant cell suspension culture of Thevetia peruviana (Pers.) K. Schum. in shake flask and stirred tank reactor scale: A comparative study

The aim of this work was to evaluate the effect of changing the shake flask for a stirred-tank bench bioreactor on the performance of Thevetia peruviana cultures. Maximum cell growth of 18.59 and 8.46 g DW/L for shake flask and bench bioreactor at day 14 was obtained, respectively. The end of the exponential growth phase in shake flask was correlated with total sugar consumption, while this behavior was not observed in...
