Study of the influence of medium composition on motility and aggregation of recombinant Escherichia coli strain BL21(DE3)/pCC90-M9 + 0.5% cassaminic acids, M9 + 0.5% cassaminic acids + 0.2% glucose, M9 + 0.5% cassaminic acids + 0.5% glucose

Microbial motility is a fundamental aspect of many microbial life cycles and is a key survival mechanism that enables microorganisms to navigate diverse and dynamic environmental conditions. This phenomenon becomes particularly important in response to changes in stimuli in time and space. The following experiment aimed to investigate how the composition of the growth medium affects the movement and formation of aggregates of recombinant Escherichia coli strains.
This study focused on several recombinant strains: BL21(DE3)/pCC90, BL21(DE3)/pACYCpBAD, BL21(DE3)/pCC90 Dra D-mut, BL21(DE3)/pCC90 D54-STOP, AAEC191A/pCC90, AAEC191A /pACYCpBAD, AAEC191A/pCC90 Dra D-mut and AAEC191A/pCC90 D54-STOP. The experimental setup involved transferring a small portion of overnight cultures of these recombinant strains to various media compositions. These media include PBS, PBS + 0.2% glucose, PBS + 0.5% glucose, LB, LB + 0.2% glucose, LB + 0.5% glucose, M9 + 0.5% cassaminic acids, M9 + 0.5% cassaminic acids + 0.2% glucose and M9 + 0.5% cassaminic acids + 0.5% glucose.
The catalog contains original video data that can be played using Olympus' CellSense software. The videos contain full layers of data characterizing the image recording process.

微生物运动是诸多微生物生命周期的核心特征，亦是帮助微生物在多样且动态的环境条件中定向移动的关键生存机制。该现象在应对时空尺度上的刺激变化时尤为关键。本实验旨在探究生长培养基的组成如何影响重组大肠杆菌菌株的运动与聚集体形成。

本研究聚焦于以下多株重组菌株：BL21(DE3)/pCC90、BL21(DE3)/pACYCpBAD、BL21(DE3)/pCC90 Dra D-mut、BL21(DE3)/pCC90 D54-STOP、AAEC191A/pCC90、AAEC191A/pACYCpBAD、AAEC191A/pCC90 Dra D-mut及AAEC191A/pCC90 D54-STOP。实验流程为将上述重组菌株的过夜培养物小体积转接至不同组分的培养基中，所用培养基包括：磷酸盐缓冲液（Phosphate Buffered Saline, PBS）、PBS + 0.2%葡萄糖、PBS + 0.5%葡萄糖、LB培养基、LB + 0.2%葡萄糖、LB + 0.5%葡萄糖、M9培养基 + 0.5%酪蛋白氨基酸、M9 + 0.5%酪蛋白氨基酸 + 0.2%葡萄糖，以及M9 + 0.5%酪蛋白氨基酸 + 0.5%葡萄糖。
