Several studies have indicated that plants are good sources of antimicrobial agents and pharmaceuticals. The present study is focused to evaluate the antimicrobial potential of 11 citrus essential oils (EOs) and terpenes (T), against 18 bacterial pathogenic strains and 4 Candida sp. strains. Volatile compounds present in the citrus EOs were determined by a gas chromatography analysis, allowing the identification of 79 components. Results highlights that lemon, bergamot oil and terpene were effective against more than 54.5% of tested bacteria. Candida spp. strains resulted very sensitive to all terpenes and EOs. Gram negative bacteria showed lower sensitivity than Gram positive ones. Among Gram negative, fish pathogens were sensitive to oils, so we suggested their use as possible alternatives in aquaculture farms to prevent bacterial fish diseases. Moreover, results suggested that citrus oils could be a useful tool in the food industry to prolong the shelf‐life.

柑橘精油对病原菌和念珠菌菌株抗菌活性的筛选

多项研究表明，植物是抗菌剂和药物的良好来源。本研究的重点是评估11种柑橘精油（EOs）和萜烯（T）对18种细菌致病菌株和4种念珠菌sp。的抗菌潜力。株。通过气相色谱分析法测定柑橘类EO中的挥发性化合物，从而鉴定出79种成分。结果表明，柠檬，佛手柑油和萜烯对超过54.5％的受试细菌有效。念珠菌属spp。菌株导致对所有萜类和EOs非常敏感。革兰氏阴性菌的敏感性低于革兰氏阳性菌。在革兰氏阴性菌中，鱼类病原体对油脂敏感，因此我们建议将其用作水产养殖场的可能替代品，以预防细菌性鱼类疾病。此外，结果表明，柑橘油可能是食品工业中延长货架期的有用工具。
