An algae cultivation jar and the algae air conditional machine are disclosed. The algae cultivation jar includes: a tank body and a multi-hole air outlet. The tank body has an air inlet and an air outlet, which are arranged at the upper part or the side part of the tank body. The tank body can store the algae cultivation solution. The side wall of the tank body is made by the transparent material. The multi-hole air outlet is arranged inside the bottom of the tank body, air connected with the air inlet and has a plurality of micro-holes. The air from the air inlet is flow to the multi-hole air outlet and passing through the algae cultivation solution. The algae inside the algae cultivation solution can depends on the air and the light to generate oxygen, then the oxygen can be exhausted out of the air outlet.一種微藻養殖罐及微藻空氣清淨機,微藻養殖罐包含:一槽體,具有一進氣開口、一出氣口,該進氣開口、該出氣口設置於該槽體之頂面或側邊,該進氣開口形成於該槽體的頂面或側邊,該槽體內部用以儲存一藻類培養原液,該槽體的側壁為透光材質製成;及一多孔型出氣部,由該進氣開口連接後配置於該槽體內的底部,該多孔型出氣部具有複數個微小孔洞,該進氣開口所進入的氣體可由該些微小孔洞排出而進入該藻類培養原液中,藉由該出氣口將該藻類培養原液中的微藻所進行的光合作用所產生的氧氣排出。10‧‧‧微藻養殖罐11‧‧‧槽體13‧‧‧內凹側壁14‧‧‧出氣口15‧‧‧提握部21‧‧‧進氣閘22‧‧‧多孔型管路
