气味沙雷氏菌是一种拮抗根际细菌，能释放出多种复杂的挥发物。三种不同的体外实验培养体系表明，这些挥发物对拟南芥的生长有促进作用。细菌在密闭培养皿中的CO2捕获和CO2浓度的显著升高(在24 h内为390-3000ppm CO2)证实了根际细菌CO2对海桑生长的增强效应。相反，开放式共培养取消了促进生长的作用，而抑制作用在环境二氧化碳浓度下表现得尤为明显。(C)2009年欧洲生化学会联合会。爱思唯尔出版公司版权所有。
Serratia odorifera, an antagonistic rhizobacterium, emits a diverse and complex bouquet of volatiles. Three different in vitro experimental culture systems indicated that these volatiles promote the growth of Arabidopsis thaliana. CO2 trapping and significant rise of CO2 levels (390-3000 ppm CO2 within 24 h) due to bacterial growth in sealed Petri dishes verified the enhanced effects of rhizobacterial CO2 on A. thaliana's growth. In contrast, open cocultivations abrogated growth promotion, and inhibitory effects come to the fore at ambient CO2 concentrations. (C) 2009 Federation of European Biochemical Societies.
