In aerobic yeast fermentation for production of citric acid from alkanes using a fed-batch culture, why alkanes are slowly fed to the yeast?

#Section 5: Bioprocess Engineering and Process Biotechnology
  1. Citric acid is toxic to the cells
  2. Alkanes cause foaming
  3. Fast addition of alkanes will inhibit the cells and reduce oxygen transfer rates
  4. Fast addition of alkanes will cause the cells to grow too quickly
