Abstract
The transcriptomes of logarithmic- and stationary-phase Pseudomonas aeruginosa planktonic cultures and static biofilms of different stages of development were compared. Developing and confluent biofilm transcriptomes were found to be related to those of logarithmic- and stationary-phase planktonic cultures, respectively. In addition, a number of novel genes were up-regulated in developing and confluent biofilms, including genes encoding putative solute transport proteins and transcriptional regulators, respectively.
摘要
比较了对数期和稳定期铜绿假单胞菌浮游培养物以及不同发育阶段静态生物膜的转录组。发现发育中的生物膜转录组和汇合生物膜转录组分别与对数期和稳定期浮游培养物的转录组相关。此外，一些新基因在发育中的生物膜和汇合生物膜中上调，分别包括编码假定溶质转运蛋白和转录调节因子的基因。
