Abstract

Green macroalgae Caulerpa racemosa from the waters of Lemukutan Island was isolated to obtain its endophyte fungi. Endophyte fungi were explored to determine their potential as antibacterial. Isolation of endophyte fungi was carried out by dilution method using PDA media. Endophyte fungi with different morphology were obtained as many as 4 isolates, named CRF1, CRF2, CRF3 and CRF4. Antibacterial activity testing was carried out by agar diffusion method. Endophyte fungi isolate CRF3 showed the best activity against Escherichia coli bacteria while CRF2 isolate showed the best activity against Staphylococcus aureus with inhibition zone diameters of 15.83 mm and 11.99 mm, respectively. Keywords:Endophyte Fungi, Caulerpa racemosa, Antibacterial, Lemukutan

利莫顿岛水的内生真菌racemosa的抗菌活动
从Lemukutan岛海域分离出绿色大藻总状茎藻(Caulerpa racemosa),获得其内生真菌。对内生真菌进行了探索,以确定其抗菌潜力。采用PDA培养基稀释法分离内生真菌。不同形态的内生真菌多达4株,分别命名为CRF1、CRF2、CRF3和CRF4。采用琼脂扩散法测定其抑菌活性。内生真菌CRF3对大肠杆菌的抑菌活性最好,CRF2对金黄色葡萄球菌的抑菌活性最好,抑菌带直径分别为15.83 mm和11.99 mm。关键词:内生真菌;总状茎孢;抗菌
