Method for cultivating marine microalga

The invention belongs to the technical field of algae culture, and discloses a method for culturing marine microalga. The method comprises the following steps: taking the marine microalga in a logarithmic growth period, inoculating a container containing a culture solution with the 5%-7% marine microalga according to the inoculation amount, controlling light intensity to be 5000-10000 lx, light todark ratio to be 12:12, water temperature to be 25-26 DEG C and pH to be 7.5-8, and culturing the marine microalga for 6-8 days. The culture method is simple and implementable, the algae cell proliferation speed is high, and the cost is low. 本发明属于藻类培养技术领域，公开了种培养亚心型扁藻的方法，其包括如下步骤：取对数生长期的亚心型扁藻，按照5-7%的接种量接种到含有培养液的容器中进行培养，控制光强为5000-10000lx，光暗比为12:12，水温为25-26℃,pH为值7.5-8，培养6-8天。本发明培养方法简单可行，藻细胞增殖速度快，成本低廉。
