Colletotrichum is the causal agent of anthracnose in passion fruit crops, generating economic yield losses. Antagonistic microorganisms represent highly efficient alternatives for chemical compounds in controlling the anthracnose disease. In this research, 8 yeast strains (M1-M8) were isolated, characterized and their antagonistic activities against Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. were evaluated in vitro. The physiological assessments showed that potential antagonistic morphotypes (M2, M5 and M7) had optimal growth with distinct conditions: 3-5 pH, 30°C, 1-5% NaCl; and assimilated several carbon sources. These morphotypes exhibited low enzymatic activity on plant polymers. According to the physiological and inhibition tests, M2 appears to be a promising biocontrol agent against C. gloeosporioides. M2 was identified as the species Meyerozyma caribbica Kurtzman & M. Suzuki.

具有对抗炭疽菌（Pelet。gloeosporioides）（Penz。）Penz的拮抗活性的酵母菌株。＆Sacc。及其表型表征

炭疽菌是百香果作物中炭疽病的病原体，造成经济产量损失。拮抗微生物是控制炭疽病的高效替代化合物。在这项研究中，分离，表征了8株酵母菌株（M1-M8）及其对Colletotrichum gloeosporioides（Penz。）Penz的拮抗活性。＆Sacc。在体外进行了评估。生理学评估表明，潜在的拮抗形态型（M2，M5和M7）在以下条件下具有最佳生长：3-5 pH，30°C，1-5％NaCl；并吸收了几种碳源 这些形态型对植物聚合物表现出低酶活性。根据生理和抑制测试，M2似乎是有希望的抗球孢梭菌的生物防治剂。
