从韩国农田黄瓜根际分离出的细菌 C1010 可以降解微生物群体感应分子己酰高丝氨酸内酯 (HHSL) 和十八酰高丝氨酸内酯 (OHSL)。形态特征和16S rRNA序列分析将C1010鉴定为不动杆菌属。菌株C1010。该菌株能够降解生物防治细菌绿针假单胞菌 O6 和植物病原细菌荚壳伯克霍尔德氏菌产生的酰基高丝氨酸内酯 (AHL)。共培养研究表明，C1010 使 AHL 失活，抑制了绿针藤 O6 产生吩嗪。在毒力测试中，C1010 菌株减轻了胡萝卜软腐欧文氏菌引起的软腐病症状。胡萝卜科。我们建议不动杆菌属。菌株 C1010 可能是一种有用的细菌，可以操纵各种革兰氏阴性细菌中受 AHL 调节的生物功能。
A bacterium C1010, isolated from the rhizospheres of cucumbers in fields in Korea, degraded the microbial quorum-sensing molecules, hexanoyl homoserine lactone (HHSL), and octadecanoyl homoserine lactone (OHSL). Morphological characteristics and 16S rRNA sequence analysis identified C1010 as Acinetobacter sp. strain C1010. This strain was able to degrade the acyl-homoserine lactones (AHLs) produced by the biocontrol bacterium, Pseudomonas chlororaphis O6, and a phytopathogenic bacterium, Burkholderia glumae. Co-cultivation studies showed that the inactivation of AHLs by C1010 inhibited production of phenazines by P. chlororaphis O6. In virulence tests, the C1010 strain attenuated soft rot symptom caused by Erwinia carotovora ssp. carotovora. We suggest Acinetobacter sp. strain C1010 could be a useful bacterium to manipulate biological functions that are regulated by AHLs in various Gram-negative bacteria.
