Key role of teichoic acids on aflatoxin B1 binding by probiotic bacteria.
It is a partially deacylated polymer of (3-1, 6-N-acetylglucosamine, which, with the other polymers such as teichoic acids and proteins, can form a major part of the extracellular matrix.
Another 29 reviews consider such topics as mechanisms of acid resistance in Escherichia coli, microbial contributions to phosphorus cycling in eutrophic lakes and wastewater, wall teichoic acids of Gram-positive bacteria, biological consequences and advantages of asymmetric bacterial growth, prions and the potential transmissibility of protein misfolding diseases, and the wonderful world of archaeal viruses.
Teichoic acids and O-specific polysaccharides may be used as adhesins by Gram-positive and Gram-negative bacteria, respectively.
This has been attributed mainly to the abundance of teichoic acids in the Gram positive peptidoglycan layer and the fact that the peptidoglycan layer in Gram negative bacteria is hidden behind the outer membrane which has a lower binding capacity (Beveridge 1988).
