Помимо огромной питательной ценности, пластичность метаболизма и высокий КПД фотосинтеза индуцирует активное изучение и оптимизацию условий культивирования хлореллы. Вследствие фототрофного типа питания, наиболее целесообразным будет изучение влияния других факторов в условиях оптимального энергетического обеспечения клетки, иначе данные, полученные при оптимизации роста хлореллы, будут способствовать более быстрому росту в условиях энергетического лимитирования, что далеко не всегда будет воспроизводиться при оптимальных условиях освещения.

В данной статье рассмотрено влияние силы света на рост хлореллы и показано, что максимальную скорость роста хлорелла демонстрирует при культивировании в области 19,0 кЛк, при этом увеличение силы света выше данного диапазона не ведет к увеличению скорости роста хлореллы и значительно изменяет ее пигментный состав.

Так же приведена математическая модель, объясняющая влияние удельной поверхности освещения на продуктивность культивирования и с ее помощью показано, что поверхность освещения более критично, чем сила света влияет на рост микроводорослей.

In addition to the enormous nutritional value, the plasticity of metabolism and the high efficiency of photosynthesis induce active study and optimization of chlorella cultivation conditions. Due to the phototrophic type of nutrition, it would be most appropriate to study the influence of other factors under conditions of optimal energy supply to the cell, otherwise the data obtained when optimizing the growth of Chlorella will contribute to faster growth under conditions of energy limitation, which will not always be reproduced under optimal conditions. lighting conditions.

This article examines the effect of light intensity on the growth of chlorella and shows that chlorella exhibits the maximum growth rate when cultivated in the region of 19.0 kLx, while an increase in light intensity above this range does not lead to an increase in the growth rate of chlorella and significantly changes its pigment composition.

A mathematical model is also presented that explains the influence of the specific surface area of illumination on the productivity of cultivation and with its help it is shown that the surface area of illumination is more critical than the intensity of light on the growth of microalgae.
