Summary
Exopolysaccharides (EPSs) are key to microbial communication and community structure. This review explores how EPSs regulate microbial signaling, quorum sensing (QS), and ecosystem dynamics, offering insights for microbial ecology.
Area of Science:
- Microbial Ecology
- Biochemistry
Background:
- Microbial interactions are fundamental to ecosystem function.
- Exopolysaccharides (EPSs) are crucial extracellular polymers produced by microorganisms.
- The role of EPSs in mediating microbial interactions is complex and multifaceted.
Purpose of the Study:
- To review the diverse roles of exopolysaccharides (EPSs) in microbial ecosystems.
- To elucidate the involvement of EPSs in microbial signaling and quorum sensing (QS).
- To highlight the impact of EPSs on microbial community dynamics and structure.
Main Methods:
- Literature review of existing research on microbial exopolysaccharides.
- Analysis of studies focusing on EPSs in microbial signaling and QS.
- Synthesis of findings related to EPSs' influence on community dynamics.
Main Results:

01:30Bacterial Signaling
31.7K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

14.5K
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...

01:23Overview of Cell Signaling
20.2K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

01:14Glycocalyx and its Functions
3.7K
The glycocalyx is a carbohydrate-rich, fuzzy-appearing layer on the outer surface of the cell membrane. It is highly hydrophilic, because of this it attracts large amounts of water to the cell's surface. This aids the cell's interaction with the watery environment and also helps it to obtain substances dissolved in the water. It is also important for cell identification, self/non-self determination, and embryonic development and is used in cell-to-cell attachments to form tissues.

47.8K
Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.
