Phosphorus limitation was found in the fermentation production of lincomycin based on the phosphorus elemental analysis. Phosphorus was thus fed into the fermentation system to improve the lincomycin production, and 16kg fed-phosphorus increased the lincomycin yield by 14.4% compared to that without the phosphorus feeding. As low concentration of dissolved oxygen limited the growth of mycelia, the...
A crude extract from Fusarium oxysprum caused significant cell apoptosis in suspension cultures of Taxus chinensis var. mairei as determined by transmission electron microscopy, DNA gel electrophoresis and terminal deoxynucleotidyl transferase-mediated dUTP nick labeling (TUNEL) analysis. Cells of T. chinensis var. mairei responded to the fungal elicitors by altering the general phenylpropanoid pathway...
