It has been reported in the literature that exposure of microalgae cells to audible sound could promote growth. This study examined the effect of sound waves with the frequency of 1100 Hz, 2200 Hz, and 3300 Hz to stimulate the biomass productivity of an Oklahoma native strain, Picochlorum oklahomensis (PO). The effect of the frequency of sound on biomass mass was measured. This study demonstrated that audible sound treatment of the algae cultures at 2200 Hz was the most effective in terms of biomass production and volumetric oil yield.
文献报道称，微藻细胞暴露在可听声中可以促进生长。本研究考察了频率为 1100 Hz、2200 Hz 和 3300 Hz 的声波对俄克拉荷马本土菌株 Picochlorum oklahomensis (PO) 的生物量生产力的刺激作用。测量了声音频率对生物量质量的影响。本研究表明，在藻类培养物中以 2200 Hz 的频率进行可听声处理在生物量生产和体积产油方面最为有效。
