It's widely believed that a "bed of nails" surface destroys bacteria through puncturing the cell wall. But new research ... The authors conclude with a diagram comparing the old model of cell death ...

In this simplified diagram of gram staining, bacterial cells are first treated ... A gram-negative cell’s thin wall crumbles in the alcohol wash and releases the dye, he explains.

However, it was not until the early 1950s that scientists started to understand the differences in the chemical composition of bacterial cell walls that makes a difference in the staining.

New transporter for recycling of bacterial cell wall found Date: January 26, 2023 Source: Umea University Summary: A transporter which some bacteria use to recycle fragments of their cell wall has ...

Bacteria are single-celled organisms and the cell wall that surrounds their plasma membrane, is made from a polymer (rather like a mesh) of amino acids and sugars. This wall is a crucial structure ...

For bacteria, the first line of defense is the cell wall, which keeps toxins such as antibiotics out. Now, researchers have discovered a key mechanism that bacteria use to build their cell walls ...

Lehigh's Marcos Pires receives NIH Maximizing Investigators' Research Award (MIRA) for his work on bacterial cell wall changes in response to antibiotics, important for next-generation drug design ...
