EVALUATION OF MECHANICAL AGITATION EFFECT ON MICROSCOPIC FILAMENTOUS FUNGI CULTURING EFFICACY
Journal Title: Вісник Національного Авіаційного Університету - Year 2017, Vol 71, Issue 2
Abstract
Goal: to review the existing literature about the effects of agitation modes on viability and productivity of filamentous fungi in submerged cultivation conditions in order to select the cultivation mode with the resulting maximum product yield for different types of micromycetes. To find relationship between agitation speed, cell morphological structure of the filamentous fungi and their ability to biomass accumulation and synthesis of metabolites. Methods: A number of articles describing the agitation modes used in laboratory fermenters with mechanical agitation devices were analysed. The experiments were carried out for the selected agitator type by variation of agitation device rotation frequency in the apparatus. Measurements of accumulated biomass and synthesized metabolites was carried out after a specified period of time throughout the period biosynthesis .Results: The analysis showed that mechanical agitation intensity in the submerged cultivation plays an important role in productivity and morphological structure of the filamentous fungi. The recommended average stirrer rotation frequency is 120-180 rpm. A direct relationship between agitation speed between cell structure and level of synthesized metabolites of micromicetes was found but studies which would describe the mechanism of agitation of the cells of filamentous fungi were not revealed.
