Keywords:
fungi, biomass, lipids, fatty acids, cultivation temperature.Abstract
This study was carried out to determine the influence of cultivation temperature of filamentous fungi Fusarium sp., P. raistrickii, P. anatolicum on the biomass, lipids yield and total fatty acids content. It is shown that more intensive accumulation of biomass and lipids was observed at temperature 18°C. The temperature decreasing from 28 to 18°C tended to increasing FA unsaturation.References
