An algae culture system of the present invention includes a container, an air supply device, a lamp, and a tube unit. The container defines a receiving space. The air supply is used for supplying carbon dioxide to the receiving space. The lamp is used for lighting up the receiving space. The tube unit includes a first tube communicating between the receiving space and the outer environment and a second tube having a valve. The second tube selectively communicates between the receiving space and the outer environment. As such, the elements and the equipment of the present invention are disposed on the container integratedly, sothe whole volume of the present invention can be reduced, thus the present invention does not occupy too much space. Furthermore, the present ionvention is convenient for users to manage, repair, and maintenance, hereby the costs of the present invention are reduced and the convenience of culturing the algae is increased.本發明提供一種微藻培養系統,包含有一容器、一供氣裝置、一燈具及一管路單元。該容器圍構有一容置空間;該供氣裝置用以供應二氧化碳至該容置空間;該燈具用以將光源照射至該容置空間;該管路單元包含一第一管路及一第二管路,該第一管路用以讓該容置空間與外部連通,該第二管路設有一水閥,使該第二管路可選擇性地讓該容置空間與該外部連通。藉此,本發明將各元件設備整合設於容器上,此舉能簡化整體之體積以減少佔用空間,再者,亦方便使用者作後續之管理及維修保養,藉以降低設備成本並增進藻類培養之便利性。1...容器2...供氣裝置3...燈具41...第一管路42...第二管路51...顯示螢幕
