**Bengaluru, India -** Researchers at the National Centre for Biological Sciences (NCBS) have unveiled a new understanding of how the three-dimensional (3D) structure of environments impacts bacterial growth and survival.
Traditionally, scientists have studied bacteria in simplified environments like liquid cultures or flat plates. However, this research, published on November 13th, 2024, sheds light on the critical role that shape plays in bacterial success in complex, natural settings such as mucus and soil.
Lead author Sreepadmanabh M. highlights the importance of considering environmental factors beyond just chemical and genetic influences: “While past research taught us about mutations and signals, we lacked insight into the impact of physical surroundings on bacterial survival.”
The study, led by Dr. Tapomoy Bhattacharjee, utilized a 3D model mimicking the properties of mucus, created using a thickening agent called Carbomer. Through simulations and microscopy, the researchers observed that rod-shaped bacteria thrive in confined spaces due to their ability to elongate and spread. Conversely, spherical bacteria form clustered colonies, where the center struggles to access air and nutrients, resulting in slower growth.
“This study opens exciting avenues for future research,” says Dr. Bhattacharjee. “Understanding the interaction between physical environments and bacteria could have implications for everything from disease development to the evolution of microbial communities.”
