Effect of pesticides on total phospholipids of hansenula anomala

Cells of Hansenula anomala were found to contain an altered phospholipid when grown under aerobic or anaerobic conditions in the presence of a fungicide, tilt, insecticide, dimecron and acardicide, Neoron. Experimental results indicate that the level of phospholipids have a significant positive correlation with increasing the concentration of any of the three pesticides under test. Also the level of phospholipids for yeast cells grown aerobically were higher than those grown under anaerobic conditions

Effect of propiconazol on amino acid compositions of some yeasts

Amino acid pool was extracted from Hansenula anomala, Candida guilliermondii and Rhodotorula rubra grown under aerobic and anaerobic conditions in the presence of different concentrations of Propiconazol [Tilt] used as a fungicide. The levels of free amino acids in these yeasts showed remarkable fluctuations and decreases. Higher changes occurred in both quantitative and qualitative levels of the free amino acid pools when the yeasts under investigation were grown in increasing growth-inhibitory concentrations of Propiconazol. However, it was found that the concentrations of total free amino acids are lower when these yeasts are grown on medium containing a fungicide
